Front

What is a missense mutation?

Back

A type of point mutation that results in a completely different amino acid being produced.

Front

What is a nucleotide?

Back

The basic building block of DNA and RNA, consisting of a phosphate group, a nitrogenous base, and a five-carbon sugar.

A type of point mutation that results in the same amino acid being produced.

Front

What is the role of DNA?

To store and transmit genetic information.

Front

What is the role of RNA?

Back

To help in the synthesis of proteins based on the genetic information in DNA.

Front

What is a frameshift mutation?

Back

A type of mutation that shifts the reading frame of the genetic code, potentially altering all subsequent amino acids.

Front

What is a nonsense mutation?

Back

A type of point mutation that creates a premature stop codon, leading to incomplete proteins.
