DNA polymerases add nucleotides to the 3' end of a growing DNA strand during DNA replication. The 3' end of the strand contains a free hydroxyl (-OH) group.

During DNA replication, the DNA double helix is unwound at the replication fork, and the two strands are separated to create a single-stranded template for DNA synthesis. The leading strand is synthesized continuously in the 5' to 3' direction, while the lagging strand is synthesized in short fragments called Okazaki fragments in the opposite direction.

In both cases, DNA polymerases add nucleotides to the 3' end of the growing DNA strand. The incoming nucleotide base-pairs with the complementary base on the template strand, and the polymerase adds the new nucleotide to the 3' end of the growing strand by forming a phosphodiester bond between the 3' hydroxyl (-OH) group of the last nucleotide in the strand and the 5' phosphate group of the incoming nucleotide.

The statement about exotoxins that is generally false is C) They are resistant to heat.

In the field of science, exotoxins can be described as toxic compounds that are produced by microorganisms and can diffuse to a host cell in order to produce toxicity.

Exotoxins are protein molecules that are secreted by a bacteria in order to protect itself. Exotoxins are heat liable, which means that they can be degraded by heat just like normal proteins. Hence, exotoxins are not compounds that are considered to be resistant to heat.

The exotoxins are produced by gram-positive as well as gram-negative bacteria and have a specific mode of action too.

Explanation:

A: Limb C is not homologous to limbs A and B, indicating structural differences.

B: Limbs A and C are analogous, as they have similar functions but distinct skeletal structures.

A: The limb that is not like the other two limbs is limb C. Limb C is not homologous to limbs A and B. The reason for this is that limb C is structurally different from limbs A and B. Limb A and limb B share similar bone structure, joint arrangement, and overall organization, indicating homology. However, limb C has a different number of digits and a distinct bone structure, suggesting that it is not homologous to limbs A and B. Instead, limb C is likely analogous, meaning it evolved independently to serve a similar function in a different organism.

B: Limbs A and C are analogous to each other. Although they have similar functions, they are not homologous. Limb A and limb C belong to different organisms and have different underlying skeletal structures. They evolved independently in their respective lineages to perform similar tasks, like grasping or locomotion. The presence of five digits in limb A and three digits in limb C further indicates their distinct origins. Despite the functional similarity, the differences in their anatomy and evolutionary history classify limbs A and C as analogous rather than homologous.

The diameter of a capillary tube is 2.5135m

Capillary tubes are those with very small diameters (narrow cylindrical tubes). When these small tubes are immersed in a liquid, the liquid in the capillary either rises (or lowers) relative to the surrounding liquid level. This phenomenon is known as capillary action, and such tubes are known as capillary tubes.

Rise in capillary is given by

h = \(\frac{2\times \sigma \times cos\theta}{\rho \times r\times g}\)

σ = surface tension

ρ = density of liquid

r = inner radius

h = height

θ = contact angle made by the liquid meniscus with the capillary’s surface.

Given,

h = 1.21 cm

σ = 540 × 10 N/m

θ = 140°

ρ = 13.6 × 10³ Km

Substituting the value in equation,

h = \(\frac{2\times \sigma \times cos\theta}{\rho \times r\times g}\)

r = \(\frac{2\times 540\times10\times cos140}{13.6\times10^3\times1.21\times10^-^2\times10}\)

r = 50.27 × 10⁻¹m

According to the research, the correct answer is genetic cloning. This technology is used by scientists to manipulate heritable information by producing large amounts of identical recombinant DNA molecules.

It is the technological process by which a cell population with identical phenotype is obtained, producing genetically exact copies of the original DNA molecules.

In this sense, the genes are responsible for the characteristics of an individual being transmitted to the offspring, being the DNA sequence of the organism necessary to manipulate and clone the cells.

Therefore, we can conclude that genetic cloning is the technology through which exact copies of cells are obtained, whose heritable information is stored in dna molecules.

Answer: each water molecule attracts other water molecules because of the opposite charges between them, forming hydrogen bonds

Because of their significant influence on the characteristics of water, hydrogen bonding and polarity are essential to water molecules.

Hydrogen bonds can form between adjacent water molecules due to the polarity of water, with the oxygen atom being slightly negative and the hydrogen atom being slightly positive. Water's high surface tension, cohesive properties, and ability to dissolve various compounds are all affected by these hydrogen bonds.

Additionally, water has a large heat capacity due to hydrogen bonding, which allows it to slowly absorb and release heat, thereby regulating the temperature of both living things and their environment. Hydrogen bonding also contributes to the anomalous density of water, which reaches its greatest density at 4 °C.

The roles do restriction enzymes, vectors, and host cells play in recombinant dna studies is cut DNA at specific sites

Restriction enzymes play a crucial role in recombinant DNA studies by cutting DNA at specific sites, which allows for the manipulation of DNA sequences. These enzymes are used to create fragments of DNA that can be inserted into vectors, which are typically plasmids, bacteriophages, or cosmids that receive foreign DNA through ligation. Vectors act as delivery vehicles for the foreign DNA, allowing it to be introduced into a host cell.

Host cells are another key component in recombinant DNA studies, they are used to express the foreign genes introduced in the recombinant DNA. The host cell's machinery is used to transcribe and translate the foreign genes, producing the desired protein product. In summary, restriction enzymes are used to cut DNA, vectors are used to deliver foreign DNA into host cells, and host cells are used to express the foreign genes. Together, these three  components are essential in recombinant DNA studies, which are used for a wide range of applications, including the production of recombinant proteins, gene therapy, and genetic engineering.

Explanation:

A pair of chromosomes that are similar but genetically different is known as homologous chromosomes. Homologous chromosomes are pairs of chromosomes that are similar in size, shape, and genetic content. They are found in diploid organisms, which have two sets of chromosomes in each of their cells. Homologous chromosomes are important because they help ensure that an organism's genetic information is correctly inherited and passed down to its offspring.

During meiosis, the process of cell division that produces gametes (sex cells), homologous chromosomes pair up and exchange genetic material through a process called recombination. This process helps to create genetically diverse offspring, as it allows for the shuffling and mixing of genetic information from both parents. Homologous chromosomes are a key feature of eukaryotic cells and play an important role in the development and function of organisms.

The osmosis diagram is the one that most accurately represents how a plant cell might change in appearance after spending thirty minutes in a concentrated sugar solution.

Osmosis is the process by which water molecules move from an area with a lower concentration of solutes to an area with a higher concentration of solutes across a semi-permeable membrane.

If a concentrated sugar solution were present, the solute concentration outside the plant cell would be higher than that inside.

Water from inside the plant cell would naturally try to exit the cell as it is submerged in the concentrated sugar solution in an effort to balance the solute concentration on either side of the cell membrane.

The DNA of eukaryotic organisms being present in the nucleus while the protein-synthesizing organelle, the ribosome being present in the cytoplasm poses a spatial problem. It means that transcribed DNAs (messenger RNA) in the nucleus would have to somehow be transported to the ribosome in order for the cell to successfully synthesize proteins.
