Front

What is the function of DNA?

Back

To store genetic information.

Front

What is the role of RNA in protein synthesis?

Back

To transfer genetic information from DNA to the ribosome.

Front

What are mutations?

Back

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

Front

What is the difference between transcription and translation?

Back

Transcription is the process of copying DNA to RNA; translation is the process of synthesizing proteins from RNA.

Front

What is a codon?

Back

A sequence of three nucleotides in mRNA that codes for a specific amino acid.
