Question

a page is to a book as a ______ is to the genome.
gene
protein
double helix
nucleotide

part d
how many polynucleotides are found in one molecule of dna?
four
two
three
one

Explanation:

A page is a part of a book, and a gene is a part of the genome. A genome is the complete set of genetic material in an organism, and genes are segments of DNA that code for specific traits or functions. DNA is a double - helix composed of two polynucleotide chains. So, for the first question, a gene is the correct analogy. For the second question, a DNA molecule consists of two polynucleotide chains that wind around each other to form a double - helix structure.

Answer:

A. gene
B. two
