Which of the following best describes a sequence of events that happens during the elongation phase of translation? Group of answer choices A charged tRNA enters the P site of a ribosome; a tRNA bound to a peptide moves to the A site; an tRNA bound to a peptide exits the E site.   None of these is an accurate description   A charged tRNA enters the A site of a ribosome; a tRNA bound to a peptide moves to the P site; an uncharged tRNA exits the E site.   An uncharged tRNA enters the A site of a ribosome; a tRNA bound to a peptide moves to the P site; a charged tRNA exits the E site.   A charged tRNA enters the A site of a ribosome; a tRNA bound to a peptide moves to the E site; an tRNA bound to a peptide exits the A site.

Which of the following statements about tRNA molecules is TRUE? Multiple Choice TRNA assumes a double helical shape Every base in a tRNA molecule pairs with another base in the same tRNA strand, leading to its higher levels of structure Bases in the tRNA loops do not pair with any other bases The amino acid is attached to the central loop region of the tRNA molecule All of the answers are correct.

The antibiotic kasugamycin blocks the binding of methionine to tRNA. From this information, you can conclude that kasugamycin prevents: transcription in prokaryotes mRNA-ribosome binding in eukaryotes the synthesis of ribosomes by rRNA in eukaryotes the initiation of the synthesis of a protein in prokaryotes             e. RNA polymerase from binding to a promoter

Which one of the following options is NOT a step in RNA processing? Addition of the 5’ G cap Addition of the 3’ poly A tail Splicing to remove exons and connect the retained introns Splicing to remove introns and connect the retained exons

A __________ molecule is characterized by having a peptide-binding site, a modified 5’ guanine, and an anticodon.   _____________ molecules are encoded by multiple gene copies in both prokaryotes and eukaryotes, and they catalyze critical reactions functions during translation.  Group of answer choices mRNA; rRNA   rNA; aminoacyl tRNA synthase   tRNA; rRNA   rRNA; precursor RNA   mRNA; tRNA

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…
