Question

in which of the following chromosomal entities are an individuals traits specified?
rna molecules
proteins
genes
nucleotides

Explanation:

Genes are segments of DNA located on chromosomes that carry the instructions for building and maintaining an organism, specifying an individual's traits. RNA molecules are involved in protein - synthesis but do not directly specify traits. Proteins are the products of gene expression and carry out functions but do not specify traits on their own. Nucleotides are the building blocks of nucleic acids (DNA and RNA) and are not the entities that specify traits.

Answer:

C. Genes
