For those individuals who have an allergic reaction to cats, a company in Los Angeles promises relief. They offer a new line of cats genetically modified to eliminate or reduce their allergy-causing properties. The development of this new line of cats most likely involved A. using natural selection to produce a new variety of cat B. altering the reproductive rate of cats C. changing the behavior of cats D. manipulating the DNA of cats

Answers

Answer: D. manipulating the DNA of cats.

Explanation:

Deoxyribonucleic acid (DNA) refers to the organic chemical which consists of genetic information. The DNA can be found in the cells of organisms.

Since the new line of cats are genetically modified to eliminate or reduce their allergy-causing properties, then we can infer that the DNA of the cats have been manipulated. In this case, the allergy causing property won't be passed across to the offspring since the DNA has been manipulated.

Answer:

Explanation:

hope this make sense:)

Macromolecules like proteins and nucleic acid are large structures that are essential for biochemical processes. The figure shows the structure of DNA.

What is DNA?

DNA is deoxyribonucleic acid that is a nucleic acid and is an important genetic material found in living organisms. It is composed of a double helix structure.

The nucleotide structure of the DNA constitutes deoxy sugar, phosphate groups, and nitrogenous bases like adenine, thymine, guanine, and cytosine.

It cannot be RNA as in RNA, uracil is present at the place of thymine. It cannot be an amino acid or protein as well because they are not composed of the amine, carboxylic, and the R group.

Therefore, the given figure is option A. DNA molecule.
