What is the role of RNA in relation to DNA?

• RNA is a type of protein that builds tissues.

• RNA stores genetic information like DNA.

• RNA replicates itself independently of DNA.

• RNA acts as a messenger and translator of genetic information from DNA to proteins.

What is a mutation in DNA?

• A mutation in DNA is a type of protein synthesis.

• A mutation in DNA is a change in the nucleotide sequence of the genetic material.

• A mutation in DNA is a process of cell division.
