What differs among DNA structures of different species?

Question

Responses
A the base pairsthe base pairs
B the nucleotide structurethe nucleotide structure
C the types of amino acids used to make proteinsthe types of amino acids used to make proteins
D the arrangement of the nucleotides within genesthe arrangement of the nucleotides within genes

Answer 1

The correct response is:

D: the arrangement of the nucleotides within genes

While the basic structure of DNA itself (including the nucleotide structure and base pairs) is generally consistent across all species, what differs is the specific sequence of nucleotides within genes, which determines the genetic information and coding for proteins in different species.
