Which best describes the structure of dna

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.

small, big, or no change could occur in the phenotype. it could cause something as simple as a cats ears to curl backwards or something as frighting as death. it could also occur in the protien-coding area and have an effect on that but no effect on the amino acids. what has to occur is a changing in the hox gene or the control gene.

the answer would be knowledge about cars!
