There are 64 codons and 20 amino acids. Which of the following is true?

• Several different codons can specify the same amino acid.

• Each codon specifies a different amino acid.

• Some amino acids have no link to a codon.

• Each amino acid is specified by only one codon.

A promoter is a

• binding site for DNA polymerase.

• binding site for RNA polymerase.

• start signal for replication.

• stop signal for transcription.

During translation, the type of amino acid that is added to the growing polypeptide depends on the

• codon the mRNA and the anticodon on the rRNA.

• anticodon on the mRNA and the anticodon on the tRNA.

• anticodon on the rRNA and the codon on the mRNA.

• codon on the mRNA and the anticodon on the tRNA.
