AUG is the most common start codon found in translated genes. Which of the following is true of these codons? The ribosome usually starts on the last AUG codon it reaches along the mRNA. An mRNA can only have one AUG codon, otherwise it might be possible to make different proteins from the same mRNA. AUG will always be used to start translation, regardless of the nucleotides immediately surrounding it. O Sometimes and AUG can be skipped because an internal ribosome entry site (IRES) can initiate translation without requiring elF4E.

Which of the following events would NOT result in ribosomes stalling on an MRNA during translation? The MRNA in a given region is very highly folded, and the ribosome stalls because the RNA structure blocks its movement. O The correct tRNA is scarce because it is not transcribed very much in the prevailing conditions. The ribosome stalls while waiting for one of the scarce tRNAS to diffuse into the A site. O the release tactor enters the A site, decodes a stop codon and transfers an oxxYgen from water to the carboxyl group of the peptidyl-tRNA in the P site, causing stalling O Starvation for amino acids will reduce the amount of amino-acylated (charged) tRNA the ribosome will stall while waiting for a charged tRNA to enter the A site to decode the next codon
Which of the following is NOT an event associated with translation termination? A stop codon enters the A site on the ribosome. A Release Factor enters the A site A terminal amino acid is added to the polypeptide to signal the end of translation. Release Factor mediates the hydrolysis of the polypeptide from the tRNA at the P site. The polypeptide and tRNA are released and the ribosomal subunits are separated.
