Front

What is the role of mRNA in protein synthesis?

Back

mRNA carries the genetic information from DNA to the ribosomes.

Front

What is a mutation?

Back

A mutation is a change in the DNA sequence that can lead to changes in protein synthesis.

Front

What is the process of transcription?

Back

Transcription is the process of copying a segment of DNA into RNA.
