Gene Expression

Front

What is the purpose of transcription?

Back

To copy DNA into a molecule of mRNA.

Front

What process does mRNA occur during?

Back

Transcription.

Front

What is a missense mutation?

Back

A mutation that results in the change of ONE amino acid.

Front

Can mutations be spontaneous?

Back

True.

Front

Where does RNA turn into protein?

Back

At the ribosome.

Front

What is the role of mRNA in gene expression?

Back

mRNA serves as a template for protein synthesis.

Front

What is the difference between transcription and translation?

Back

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

Front

What are the three types of RNA involved in protein synthesis?

Back

mRNA, tRNA, and rRNA.

Front

What is a frameshift mutation?

Back

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

Front

What is the function of tRNA?

Back

tRNA transports amino acids to the ribosome during protein synthesis.
