Protein Synthesis and Enzymes

The monomers units of DNA and RNA are

• amino acids

• monosaccharides

• nucleotides

The signal that marks the end of a gene and causes transcription to stop is

• polymerase

• ligase

• a terminator

• methionine

Which of the following enzymes catalyzes the linkage together of RNA nucleotides to form RNA?
