Front

What is a missense mutation?

Back

A mutation that results in the replacement of one amino acid with another in a protein.

Front

What are the three main types of mutations?

Back

Substitution, insertion, and deletion.

Front

What is the role of ribosomes in protein synthesis?

Back

Ribosomes facilitate the translation of mRNA into a polypeptide chain.

Front

What is the difference between transcription and translation?

Back

Transcription is the process of synthesizing RNA from DNA, while translation is the process of synthesizing proteins from mRNA.

Front

What is an example of a gene mutation?

Back

A change in the nucleotide sequence that alters the function of a gene.
