Question

characteristics such as widows peak or attached earlobes are determined by the genetic code. what components of dna are referred to as the genetic code? hydrogen bonds phosphate groups deoxyribose sugars nitrogenous bases

Explanation:

The genetic code is determined by the sequence of nitrogenous bases in DNA. These bases (adenine, thymine, guanine, cytosine) form codons that code for amino - acids and thus determine the traits. Hydrogen bonds hold the two strands of DNA together, phosphate groups and deoxyribose sugars form the backbone of the DNA molecule but do not represent the genetic code itself.

Answer:

Nitrogenous bases
