Question

21) Choose the correct answer.

How exactly does DNA determine a person's unique characteristics?
O Sections of DNA match other individuals, so you can compare and see the traits.
When machines read the physical appearance it matches it with a stored DNA of someone who had
the same code.
O
Sections of DNA, genes or chromosomes, contain instructions for making specifice proteins. These
proteins determine human traits.

Answer 1

DNA determines a person's unique characteristics through genes and proteins.

Step-by-step explanation:

Sections of DNA, genes or chromosomes, contain instructions for making specific proteins. These proteins determine human traits. Each gene on a DNA molecule codes for a protein, and different combinations of genes can lead to variations in traits. For example, a gene may code for eye color, and different variations of that gene can result in different eye colors. Therefore, DNA determines a person's unique characteristics by influencing the production of proteins that contribute to various traits.
