Effect of diminished activity of methionine adenosyl transferase on the bacteria’s DNA. Concept introduction: Methionine adenosyltransferase is an enzyme that catalyzes the synthesis of S-adenosylmethionine (SAM), by using methionine and ATP as the substrates. AdoMet acts as a methyl donor for the transmethylation reaction and propylamine donor in polyamine biosynthesis. Synthesis of SAM is the rate-limiting step in the methionine cycle.

Need help. Contrast DNA replication with gene expression (transcription→translation)—when does each occur? What molecules are involved? How much of the DNA is utilized?

Question 8 Review translation. Match the term and its description. Each term can only be used once. This site holds the tRNA that carries the growing polypeptide chain | Choose ) This site holds the tRNA that carries the next amino acid to be | Choose J added to the chain This site is the exit site, where discharged tRNAS leave the [ Choose ) ribosome Initiation, elongation and termination | Choose J >

True or False. Explain. A) At no time during protein synthesis does an amino acid make direct contact with the mRNA being translated. B) Because the two strands of DNA are complementary, the mRNA of a gene can be synthesized using either strand as a template.
