Front

What is the difference between homozygous and heterozygous genotypes?

Back

Homozygous has two identical alleles, while heterozygous has two different alleles.

What is a mutation?

Back

A change in the DNA sequence that can lead to changes in protein structure and function.

Front

What is the role of RNA in protein synthesis?

Back

RNA acts as a messenger carrying instructions from DNA for controlling the synthesis of proteins.
