A DNA Molecule is A

Question

A DNA molecule is a:
A)gene.
B)chromosome.
C)genome.
D)gamete.

Accepted Answer

A DNA molecule is a long, double-stranded, helical molecule that carries genetic information. It is the basic unit of a chromosome, which is a structure in the cell nucleus made up of DNA, RNA, and protein. Each chromosome contains many genes, which are segments of DNA that code for specific proteins. Therefore, while a DNA molecule is not a gene or a genome, it is the building block of a chromosome. A gamete, on the other hand, is a reproductive cell that carries half the genetic information of an organism and is produced during meiosis.
