DOK Level 1: Recall

During transcription, this type of ribonucleic acid is responsible for copying the DNA and brining it out of the nucleus.

• tRNA

• mRNA

• rRNA

• dRNA

If there is an error in transcription, what could happen as a result?

• The nucleotides that make up the protein will change.

• The protein that is made will not be affected.

• New amino acids will be created to make a new protein.

• The protein that is made may have a different structure or function.
