Which best describes the role of translation in helping cells code for proteins?

• The nucleotides in RNA and DNA determine the sequence of amino acids in proteins.

• The bases in messenger RNA code for the sequence of amino acids in proteins.

• The bases in transfer RNA code for the sequence of amino acids in

  proteins.

Where are proteins made?

• mitochondrion

• nucleus

• ribosome

What happens during transcription?

• DNA is used as a pattern to write mRNA

• amino acids are carried to the ribosome

• DNA is copied before cells divide
