Question

Responses
A This DNA would only be found in a human or fungus because bacteria do not have DNA.This DNA would only be found in a human or fungus because bacteria do not have DNA.
B This DNA would not be found in fungus, because fungus DNA is not made of nucleotides.This DNA would not be found in fungus, because fungus DNA is not made of nucleotides.
C All DNA has the same structure, so the modeled DNA could be found in any living organism.All DNA has the same structure, so the modeled DNA could be found in any living organism.
D This DNA would not be found in bacteria because bacteria only contain the nitrogen bases adenine, cytosine, and guanine.

Answer 1

The correct response is:

C. All DNA has the same structure, so the modeled DNA could be found in any living organism.

DNA, regardless of whether it is from bacteria, humans, or fungi, is composed of the same fundamental building blocks: nucleotides, which include a sugar, a phosphate group, and a nitrogenous base (adenine, thymine, cytosine, and guanine in eukaryotes, and adenine, uracil, cytosine, and guanine in prokaryotes). Therefore, while the specifics of the DNA sequence and organization may vary between different types of organisms, the structural components of DNA are universal across all forms of life.
