Questions and Answers

What is the shape of a DNA molecule?

Double helix (correct)

Triple helix

Single strand

Circular structure

What role do histones play in the structure of DNA?

They act as the genetic code of DNA.

They are the proteins that DNA wraps around to create nucleosomes. (correct)

They form the backbone of the DNA structure.

They are the enzymes that replicate DNA.

How are genes and alleles different?

Genes are forms of traits; alleles are the genes themselves.

Genes refer to physical traits; alleles refer to the genetic code.

Genes describe traits while alleles represent variations of that trait. (correct)

Genes are specific locations on a chromosome; alleles are versions of a gene.
