Answer:

The double helix describes the structure of DNA.

Explanation:

A self-replicating material that is present in most of the living organisms as the carrier of genetic information. Double helix refers to the structure created by double-stranded molecules of nucleic acids.

Think of the double helix structure like a spiral ladder. The sugar and phosphate molecules would be the two sides of the ladder, while the nitrogenous bases would be the rungs. Guanine pairs with cytosine, and adenine pairs with thymine.

Thus, the correct answer is a double helix.

A. What color do you want your insects to be?
Scrat [10]
Well, in terms of the science of artificial selection, mutations will be useful in achieving your goal as a genetic mutation that happens often in insects, particularly fruit flies, is a change of color. A strategy that could be used would be a Punnet square to simulate the possible crosses between the insects and which is most likely to bring out the recessive gene (the desired color). Finally, the breeding of dogs can be explained by humans breeding tall dogs with other tall dogs to ensure that the outcome would most likely be another recessive gene (tallness) and a similar set of events would explain the Pomeranian (short dogs being breed with other short dogs)  <span />
