Question

4 4pts. Match the following phrases with either OPERONS or FEEDBACK INHIBITION. Do this by writing two lists, one with OPERONS at the top and the other with FEEDBACK INHIBITION. • Regulation at the protein level • Conserves energy, nucleotides, amino acids • Regulation at the DNA or gene level • Conserves some energy • Goes into effect fairly quickly . Eventually shuts down gene expression • Uses end product to regulate enzymes . Can allow bacteria to respond to changes in their environment 5 1pts. Provide one reason why gene expression occurs quickly in prokaryotes 6 2pts. Explain how both spontaneous and induced mutations caused by mutagens) involve DNA polymerase

Answer 1

Question (4) Match the following phrones with either OPERONS 07 FEEDBACK INHIBITION - Answer= OPERONS - Regulation at the DNA or gene level. Conserver Some Energy Eventually shuts down gene expression. Can allow bacteria to serpond to change in their environment. FEEDBACK INHIBITION - - Regulation at the protein level. -> Conserves energy, nucleotider, aminoacids. Goex in to effect quickly. User end product to regulate enzymer. Question (5) Provide one reason why gene expression occurs quickly in prokaryotex. Answer = There ix no mRNA Processing ( 5 capping, splicing 3 polyadenylation) in prokaryotes and the site of Transcription and Translation are also the same liie. in the cytoxol) that's the major reason.
