true or false: a dna mutation will always affect the protein.

• false
• true

Explanation:

Question 1

A mutation is defined as a change in the DNA base sequence. Cells are the basic units of life, personality is a psychological trait, and gametes are reproductive cells; mutations are specifically changes in DNA.

Not all DNA mutations affect proteins. Silent mutations, for example, change the DNA base but not the amino acid coded for, so the protein remains unchanged. Thus, the statement is false.

Answer:

A. DNA base sequence
