Question

question 5 of 25
which statement best describes how a gene carries the information for a specific trait?
a. a gene is composed of a chromosome that has multiple alleles for the trait.
b. a gene is a sequence of proteins the cell uses to produce different alleles.
c. a gene is a protein that determines the sequence of nucleotides in dna.
d. a gene is a section of dna with instructions for assembling amino acids to make proteins.

Explanation:

A gene is a segment of DNA. DNA has the code (instructions) for making proteins. Proteins are made by assembling amino acids. Option D correctly describes this relationship. Option A is wrong as a chromosome has genes, not the other way around. Option B is incorrect as genes are made of DNA (nucleotides), not proteins. Option C is wrong as proteins don't determine DNA nucleotide sequence; DNA determines protein sequence.

Answer:

D. A gene is a section of DNA with instructions for assembling amino acids to make proteins.
