Humans and Mice Differ Because of Which of the Following

Question

Humans and mice differ because of which of the following?
A)Their cells have different small organic molecules.
B)Their cells make different types of large biological molecules.
C)Their cells make different types of lipids.
D)Their cells have some differences in the sequence of nucleotides in their nucleic acids.
E)Their cells make different types of proteins.

Accepted Answer

Humans and mice have differences in their DNA sequences, which leads to differences in the proteins produced by their cells. This is because DNA provides the instructions for making proteins through the sequence of nucleotides in the DNA code. While the basic structure of proteins is the same in all organisms, the specific amino acid sequence that makes up each protein can vary, leading to differences in their function and overall biology.
