Protein synthesis in eukaryotes is similar to the process in prokaryotes in that both eukaryotes and prokaryotes:   have introns use methionine as the "start" amino acid use codons to determine polypeptide sequences

The genetic code is Random in that the codons for the same amino acid are structurally unrelated Read by pairing codons in TRNAS with anticodons in mRNAs Read by pairing anticodons in TRNAS with codons in MRNAS Redundant in that each codon can code for multiple amino acids

of the following determines the amino acid sequence of the protein produced during the process of translation? ribosomes ribosomal RNA transfer RNA messenger RNA ATP

A protein had the amino acids leu-gly at codons 10 and 11. A deletion of the 5’ base of the leu codon (i.e. the first base) changed the protein so that it now reads ser-ala at codons 10 and 11. The original Leu codon must have been: (hint: make use of a codon table to answer this question)   CUG AUG CUA CUC      CUU

Rank from left to right the compound with the most reactive chemical linkage: peptide bond, ester, ether, acid anhydride, aminoacyl-TRNA How many bacterial translation factors are "G" proteins? How many proteins are involved in the nucleotide-dependent steps of protein synthesis?

All of the following statements about translation are true except: Release factors recognize stop codons and prompt-cleavage of a peptide bond. Initiation factors are involved in ribosome assembly. In prokaryotes, initiator transfer RNA (tRNAf) is attached to formylmethionine. Each messenger RNA contains a start codon and a stop codon.

What is the correct sequence in translation? a   tRNA attaches to start codon, ribosome attaches to mRNA in P site, new tRNA enters on A site, peptide chain moves to old tRNA in P site, old tRNA moves to E and new tRNA to P. b   tRNA attaches to start codon, ribosome attaches to mRNA in P site, new tRNA enters on A site, peptide chain moves to new tRNA, old tRNA moves to E and new tRNA to P. c   tRNA attaches to start codon, ribosome attaches to mRNA in A site, new tRNA enters on P site, peptide chain moves to new tRNA, old tRNA moves to E and new tRNA to A. d   tRNA attaches continuously to mRNA without the need of a ribosome. Proteins are: a   the direct translation of a single gene b   in most cases, the results of post-translation control c   first transcribed from DNA by an operon d   transcription factors Which of the following statements is false? a   In the lytic cycle, new phage are produced and released into the environment. b…

Enzymes in which the catalytic portion is not made of protein include all of the following except: the large ribosomal subunit self-splicing introns peptidyl transferase infectious viroids tRNA synthetase
