Question

the genetic code is composed of what? a a sequence of nitrogen bases. b a sequence of phosphates. c a sequence of sugars.

Explanation:

The genetic code is carried by DNA. DNA is composed of nucleotides, and the specific sequence of nitrogen bases (adenine, thymine, cytosine, guanine in DNA) encodes genetic information. Phosphates and sugars form the backbone of the DNA structure but do not carry the genetic code itself.

Answer:

A. A sequence of nitrogen bases.
