Number the following steps of protein synthesis in order in which they occur, starting with 1 and ending with 9. a. ____ the stop codon is reached, and the polypeptide is released b.____ the small ribosomal subunit finds the start codon, and the large ribosomal subunit joins. c.____ the end of the gene is reached, and the pre-mRNA is released and then edited. d. ____ The transcription factor bonds the promoter. e. ____ the protein is folded and modified to become functional. f. ____ RNA polymerase builds the mRNA transcript. g. ____ mRNA and initiator tRNA bind the small ribosomal subunit. h. ____ new tRNAs are brought into the A site successively, and the peptide chain of the tRNA in the P site is joined to the amino acid of the tRNA in the A site. i. ____ mRNA exits the nucleus via a nuclear pore.
Why is regulating transcription the main way that cells control gene expression? A. Because transcription is the last step in gene expression, stopping here ensures that the cell has a stockpile of proteins to prepare them from all unexpected environmental changes. B. Because transcription involves interactions with DNA, preventing transcription reduces the changes of mutation in the cell’s genome. C. Because transcription is the first step in gene expression, stopping at transcription reduces the amount of energy and resources used by producing unnecessary gene products. D. Because transcription is the shortest step in gene expression, preventing transcription has little effect on the rate of protein production.
How is translation different in prokaryotes and eukaryotes? a. In prokaryotes, because they do not have a nucleus, the translation of mRNA occurs while it is being transcribed b. In prokaryotes, pre-mRNA translation before transcription occurs within the cell c.In prokaryotes, reverse trancriptase simultaneously translates and transcribes mRNAd.In prokaryotes, functional mRNA allows for translation to be skipped, and proteins are made during transcription
