An example of Central Dogma is when DNA makes RNA through transcription, and RNA makes protein through translation.

DNA → RNA → protein.

The greatest revolution in the Central Dogma was the discovery of retroviruses that transcribe RNA into DNA using a specialized enzyme called reverse transcriptase, making an exception to the Central Dogma.

A central tenet of molecular biology is the theory that genetic information flows in only one direction, either from DNA through RNA to proteins or from RNA directly to proteins.

The central dogma of molecular biology is that DNA encodes RNA, and RNA encodes proteins. At The Central Dogma, learn about the critical roles of messenger, transfer, and ribosomal RNA in the protein assembly process.

Answer:

B. refraction

Explanation: hope this helps!

The shadow zone exists due to the effect of seismic waves is the refraction. Thus, the correct option will be B.

Refraction can be defined as the redirection of a wave as it passes from one medium to another medium. The redirection of the waves in a medium can be caused by the wave's change in speed or by a change in the medium of wave.

Seismic waves are the waves which follow the same law of refraction at the compositional boundaries. If the seismic wave velocity in the rock below a boundary is increasing then, the waves will be refracted in the upward direction and this speed up relative to their original path of movement.

Therefore, the correct option will be B.

Long and single-stranded, mRNA is made up of nucleotides joined together by phosphodiester bonds. It includes adenine, guanine, cytosine, and uracil, four nitrogenous bases.

What is the definition of mRNA?

mRNA molecules, also known as messenger RNA, transport the genetic information required to produce proteins. They transport the data from the DNA in the cell's nucleus to the cytosol, where proteins are produced.

Sizes of mRNA are determined by the amount of nucleotides in each strand. For example, the GFP protein has a quantity between 300 and 1,000 nucleotides. Alternatively, mRNA molecules such as the COVID-19 mRNA vaccine and Cas-9 have sizes between 2,000 and 4,000 nucleotides.

The base and sugar between DNA nucleotides are linked by hydrogen bonds. Option c.

DNA stands for Deoxyribonucleic acid which is a long molecule that carries genetic information and is found in the nucleus of a cell. It is composed of nucleotides that are linked together. Each nucleotide is composed of three components; a nitrogenous base, a sugar (deoxyribose), and a phosphate group. The base is attached to the sugar and the sugar is attached to the phosphate group.Hydrogen bonds are weak bonds that exist between a hydrogen atom of one molecule and the oxygen or nitrogen atom of another molecule. They occur when a hydrogen atom is covalently bonded to an electronegative atom and is also attracted to another electronegative atom. In DNA, the hydrogen bonds exist between the nitrogenous bases of nucleotides. There are four types of nitrogenous bases found in DNA; adenine (A), thymine (T), guanine (G), and cytosine (C). Adenine always pairs with thymine through two hydrogen bonds and guanine always pairs with cytosine through three hydrogen bonds. These hydrogen bonds hold the two strands of the double helix structure together.

Answer:

The body has levels of organization that build on each other. Cells make up tissues, tissues make up organs, and organs make up organ systems. The function of an organ system depends on the integrated activity of its organs. The survival of the organism depends on the integrated activity of all the organ systems, often coordinated by the endocrine and nervous systems.

Explanation:

In the human body, cells are the basic units of life. Groups of cells working together for a specific function form tissues. Organs are two or more tissues operating together. Even separate organs work together, forming body systems.

Hope this helps :) !!!

Cells form tissues, tissues combine to form organs, and organs work together to create organ systems, collectively maintaining the overall functioning of the human body.

Inside the human body, cells are the fundamental building blocks of life. They're arranged to form tissues. Organs are structures composed of different types of tissue, which perform certain functions. These organs are formed by the combination of tissues.

Organs, in turn, work together to create organ systems. Organ systems are groups of organs that work together in order to perform more extensive functions that allow a body to survive and function properly.

Transplanting the nucleus of an epithelial cell into an egg cell lacking genetic information leads to the formation of a clone with the genetic information of the donor epithelial cell.

This is because the nucleus contains genetic material in the form of DNA, which carries the instructions for the development and functioning of an organism. In the process of cloning, the nucleus of a somatic cell (such as an epithelial cell) is removed and transferred to an egg cell that has had its own nucleus removed. This egg cell then develops into an embryo that is genetically identical to the donor organism, as the genetic information comes solely from the somatic cell used in the process.

Thus, the resulting cloned organism would have the same genetic information as the epithelial cell that provided the nucleus. This process is known as somatic cell nuclear transfer (SCNT) and has been used in a variety of applications, including the cloning of animals and potentially in human therapeutic cloning in the future.

Answer: It could have a temperature difference or could be the same temperature

Explanation:

If all enzymes work at different temperatures some enzymes might work at 38 degrees C or 37 degrees c etc.

Based on the information provided, it can be inferred that Enzyme 2 is most active at a temperature different from 37 degrees Celsius, the body temperature of humans.

Enzyme activity refers to the ability of an enzyme to catalyze a chemical reaction. Enzymes are proteins that facilitate chemical reactions in the body, and they do so by lowering the activation energy required for the reaction to occur. This allows the reaction to proceed more quickly and efficiently.

Enzyme activity can be affected by various factors, including temperature, pH, and the presence of specific substrates or inhibitors. Different enzymes have optimal temperatures at which they function most efficiently, and these can vary widely depending on the enzyme and the organism in which it is found.

Some enzymes are more stable and can function over a wide range of temperatures, while others are less stable and may be denatured or become inactive at higher or lower temperatures

Pharyngeal arches found in all vertebrate embryos are homologous and the bones that support the wings of birds, pterosaurs and bats are homologous.

Pax6 gene is homologous at least to the level of a Bilateria. It is responsible for both insect compound eyes and vertebrate eyes. But the Pax6 gene originated before the origin of eyes in both lineages and must have been independently adopted by both lineages. So it is not homologous, despite seemingly appearing that it is resulting in different organs with the same origin. Pharyngeal arches found in all vertebrate embryos are homologous. The gill supports in fish and the throat structures in mammals originate from pharyngeal arches. The ability to fly using elongated wings in birds, bats, and pterosaurs is not homologous. All these wings despite having some purpose originated independently from one another. The bones that support the wings of birds, pterosaurs and bats are homologous and have the same origin despite having been used for supporting different kinds of wings.

Inactivation of a transporter in the presynaptic membrane would be expected to increase the levels of the transmitter in the synapse.

The presynaptic membrane contains transporters. The synaptic cleft is the place where the transporter works. Neurotransmitter is transported back into the cell and recycled. Because of the inactivation of a transporter in the presynaptic membrane, the transporter is no longer functional. As a result, neurotransmitters are not recycled and are trapped in the synapse. The concentration of neurotransmitters in the synapse is therefore raised.

The synaptic cleft is a gap between the presynaptic neuron and the postsynaptic neuron. When the presynaptic neuron is activated, it releases neurotransmitters into the synaptic cleft. Neurotransmitters travel from the presynaptic neuron to the postsynaptic neuron via the synaptic cleft. Transporters are in the presynaptic membrane and serve to transport neurotransmitters back to the cell to be recycled. If the transporter is inactivated, it will no longer be able to transport neurotransmitters back to the cell.
