During transcription, the adenine on the left side of the sequence was the last nucleotide added to a portion of the mRNA.

When RNA polymerase crosses the stop (termination) sequence in the gene, transcription is terminated, marking the end of the process.After the mRNA strand is complete, it is separated from the DNA. A strand of RNA that is complementary to the DNA template is made by RNA polymerase. The three phases of translation are initiation, extension, and termination. When the DNA template strand is read in the 3' to 5' direction, the RNA strand in the 5' to 3' direction is synthesized.

Translation (from mRNA to protein) and transcription (DNA to mRNA) are so closely linked in prokaryotic cells that translation often begins before transcription is complete.

Answer:

the kind of material it is moving through

Explanation:

Sound wave is a type of mechanical wave, which requires a medium to travel, unlike longitudinal waves that can travel through vacuums. Since, sound waves travel through mediums, the KIND OF MEDIUM/MATERIAL it is traveling through has a role to play on how fast it moves.

Sound waves move faster in materials whose molecules are closely packed together than those with loosely packed molecules. This is why sound waves naturally travel faster in SOLID materials. Therefore, the the kind of material the sound wave is moving through affects how fast it moves.

Answer: They don’t have microvili because they don’t need it.

Explanation:

Animal cells have this because it increase surface area and helps absorb food and water molecules.

Plant cells do not have microvilli because they do not require the same type of surface area enlargement as animal cells.

Microvilli are small, finger-like projections that extend from the surface of animal cells. They help to increase the surface area of the cell, which is important for functions such as absorption and secretion.

Whereas plant cells have a rigid cell wall that provides structural support and protection. They have evolved unique structures to meet their specific needs, such as chloroplasts for photosynthesis and a cell wall for support and protection.

So, the absence of microvilli in plant cells is not a disadvantage since they do not require the same surface area enlargement as animal cells.

Therefore, the absence of microvilli in plant cells is due to their unique structural and functional needs.

One EPSP at the postsynaptic neuron would produce a positive 2mV change in the membrane potential.

One IPSP at the postsynaptic neuron would produce a negative 2−mV change in the membrane potential. When all 12 EPSP neurons are stimulated, the total potential produced at the postsynaptic membrane is: +24mV. When all 8 IPSP neurons are stimulate the total potential produced at the postsynaptic membrane is: -16mV. If the threshold of the postsynaptic neuron is 10mV and all eight inhibitory neurons are stimulated, there are not enough excitatory neurons to generate an action potential. The answer is no.

Given that:Twenty neurons synapse with a single receptor neuron.Twelve neurons release neurotransmitters that produce EPSPs at the postsynaptic membrane, and the other eight release neurotransmitters that produce IPSPs.Each time one of the neurons is stimulated, it releases enough neurotransmitter to produce a 2−mV change in potential at the postsynaptic membrane.To solve the given questions:15. The EPSPs would produce a positive change in the membrane potential. Therefore, one EPSP at the postsynaptic neuron would produce a positive 2mV change in the membrane potential. The IPSPs would produce a negative change in the membrane potential. Therefore, one IPSP at the postsynaptic neuron would produce a negative 2−mV change in the membrane potential.

When all 12 EPSP neurons are stimulated, the total potential produced at the postsynaptic membrane can be calculated by multiplying the amplitude of one EPSP by the number of EPSPs:

12 EPSPs × 2 mV = 24mV

The total potential produced at the postsynaptic membrane is: +24mV. Wen all 8 IPSP neurons are stimulated, the total potential produced at the postsynaptic membrane can be calculated by multiplying the amplitude of one IPSP by the number of IPSPs:

8 IPSPs × 2 mV = -16m

The total potential produced at the postsynaptic membrane is: -16mV.19. The threshold for generating an action potential is 10mV. Therefore, if the inhibitory signals from the IPSPs exceed the excitatory signals from the EPSPs and prevent the membrane potential from reaching the threshold potential of 10mV, then there won't be enough excitatory neurons to generate an action potential. Thus, if the threshold of the postsynaptic neuron is 10mV and all eight inhibitory neurons are stimulated, there are not enough excitatory neurons to generate an action potential.

Hence, the answer is no.

Chemical modification of histones regulates the chromatin structure and gene expression at various stages.

Histones are proteins that help in DNA organization and packaging into chromatin. Chemical modifications of histones, such as acetylation, methylation, phosphorylation, and ubiquitination, regulate the chromatin structure and gene expression at various stages, including transcriptional activation, repression, and maintenance of chromatin states. These modifications can affect the accessibility of DNA to transcription factors and the recruitment of co-activators or co-repressors, leading to changes in gene expression. Thus, histone modifications play a crucial role in regulating the stage of gene expression.
These modifications can either promote or inhibit gene expression by allowing or preventing the binding of transcription factors and RNA polymerase to the DNA. This process is known as epigenetic regulation and plays a crucial role in gene expression control during various cellular processes, development, and disease states.

As α increases in the Lotka-Volterra competition equations, the population growth rate of species 1 decreases due to the intensified competition with species 2. The population growth rate of species 1 is determined by the difference between its birth rate and death rate.

In the Lotka-Volterra competition equations, if α increases, it affects the population growth rate of species 1. The parameter α represents the effect of species 2 on species 1. When α increases, it means that the interspecific competition between the two species becomes stronger.
The population growth rate of species 1 is determined by the difference between its birth rate and death rate. In this competition model, the birth rate of species 1 is reduced as the competition with species 2 intensifies. As a result, the population growth rate of species 1 decreases.
To understand this concept better, let's consider an example. Imagine a forest where species 1 and species 2 compete for the same food resources. If the competition between the two species becomes more intense due to an increase in α, species 1 will face more difficulty in finding enough resources to reproduce and survive. This leads to a decrease in the population growth rate of species 1.
In summary, as α increases in the Lotka-Volterra competition equations, the population growth rate of species 1 decreases due to the intensified competition with species 2.

The alteration of pseudomonas bacteria's DNA to enable them to consume oil could have both positive and negative impacts on the environment and society.

Firstly, the potential benefits include the ability to mitigate oil spills and minimize damage to marine flora and fauna. These genetically modified bacteria could be used in oil spill cleanup efforts, helping to break down and digest the spilled oil more effectively, thus reducing the environmental impact.

On the other hand, there are also potential risks associated with this biotechnology. If the modified bacteria were released into the environment unintentionally or without proper control, there could be adverse consequences. The uncontrolled spread of these bacteria could result in unintended pollution as they consume not only spilled oil but also other hydrocarbon sources, leading to the release of toxic gases and further environmental damage.

Moreover, the introduction of such bacteria could disrupt natural ecosystems, potentially affecting other microorganisms and organisms that depend on oil for survival. The long-term effects on the balance of ecosystems are uncertain and would require thorough evaluation before any large-scale implementation.

In terms of society, the development of these bacteria could have economic implications. The cleanup of oil spills could become more efficient and cost-effective, potentially reducing the financial burden on affected industries and governments. However, it is important to consider the potential risks and unintended consequences of relying solely on this biotechnology, as it may discourage the development of alternative, cleaner energy sources.

Overall, the impact of genetically modified pseudomonas bacteria with oil-consuming abilities on the environment and society would depend on how the technology is deployed, regulated, and monitored. It is crucial to carefully evaluate the potential risks and benefits to ensure responsible and sustainable implementation.

To promote a closer association of nucleosomes, heterochromatin protein 1 (HP1) recognizes the histone modification found in H3K9me3.

Heterochromatin protein 1 (HP1) is a chromatin-associated protein that plays a key role in the organization of chromatin structure. HP1 binds to chromatin via its chromodomain, which specifically recognizes histone modifications. One of the main modifications recognized by HP1 is the methylation of histone H3 at lysine 9 (H3K9me3). This modification is associated with transcriptional repression and the formation of heterochromatin, which is a more compact and condensed form of chromatin.

In conclusion, the recognition of the histone modification H3K9me3 by HP1 promotes a closer association of nucleosomes and plays a crucial role in the organization of chromatin structure.

Before transcription can begin, a process known as DNA unwinding and unzipping must take place.

Transcription is the process by which genetic information encoded in DNA is copied into a complementary RNA molecule. However, before transcription can occur, the DNA double helix must undergo unwinding and unzipping.

During DNA unwinding, the hydrogen bonds between the complementary nucleotide bases (adenine, thymine, cytosine, and guanine) are broken, causing the DNA double helix to separate into two strands. This separation exposes the DNA template strand, which serves as a template for RNA synthesis.

Once the DNA strands are unwound, the process of DNA unzipping occurs. Enzymes, such as helicase, help in separating the DNA strands by breaking the hydrogen bonds between the base pairs.

As a result, the DNA molecule is "unzipped" into two separate strands, with the template strand serving as a template for RNA synthesis.

After DNA unwinding and unzipping, the stage is set for transcription to begin. The RNA polymerase enzyme can then bind to the DNA template strand and initiate the synthesis of an RNA molecule using complementary RNA nucleotides.

Thus, DNA unwinding and unzipping are essential steps that precede the initiation of transcription.
