Which is NOT true about translation? Option A Introns are not translated. Option B The first amino acid that is translated is methionine. Option C rRNA is the translator molecule, containing an anticodon that can recognize a specific mRNA codon and bring the corresponding amino acid into place Option D Translation takes place in the ribosome.

Q1: On the ribosome, the mRNA is read from 5' to 3' in a series of three nucleotides called codons. Q2: Which of the following features of eukaryotic ribosomes in translation initiation is FALSE? a. It uses an initiator tRNA that carries a methionine. b. The large subunit of the ribosome is important for binding to the mRNA. c. The large and small subunits of the ribosome combine once the initiation complex recognizes the AUG start codon. Q3: Which of the following methods is NOT used by eukaryotic cells to regulate the amount of protein in the cell? a. Operons b. Riboswitches c. miRNAs

Which of the following statements is false? Group of answer choices - Translation consists of initiation, elongation, and termination. - rRNA of the large ribosomal subunit is also called ribozyme. - During translation initiation, the small ribosomal subunit recognizes the region on the mRNA near the start codon and attaches to it. - The start codon can be different depending on what kind of protein is to be translated.

1.Ribosomes select the correct tRNAs via interactions between the codon in the mRNA, the anticodon in the tRNA and bases of the small ribosomal RNA in the base of the A site. This describes: A. Bacterial translation B. Eukaryotic translation C. Bacterial translation and eukaryotic translation 2.The Listeria monocytogenes prfA transcript contains a riboswitch that regulates its translation. This and other bacterial riboswitches are generally characterized by the presence of: A. a short 3' untranslated region following the termination codon B. a short 5' untranslated region preceding the initiation codon C. a long 5' untranslated region preceding the initiation codon D. a long 3' untranslated region following the termination codon 3.What is the first step in the initiation of translation in bacteria? A. the 70S ribosome binds to the initiation codon on the mRNA molecule B. the small subunit of the ribosome binds to the ribosome binding site on the mRNA molecule C. the large subunit of the ribosome binds to the ribosome binding site on the mRNA molecule D. the small subunit of the ribosome binds to the 5' cap of the mRNA before scanning across the UTR until the initiation codon is reached 4.The final step of the initiation phase of translation occurs when A. A complete ribosome is formed with initiator tRNA bound to the initiation codon B. Initiation factors attach to the initiation codon C. The cap binding complex assembles around the 5' cap of the mRNA D. The aminoacyl (A) site of the ribosome occupied by the initiator tRNA 5.In the absence of high levels of steroid (e.g. glucocorticoid, estrogen), a steroid receptor would likely be found A. Bound to Hsp90 in the cytoplasm B. Bound to Hsp90 in the nucleus C. Interacting with nucleosome remodeling complexes in the nucleus D. Bound to Gal3 in the cytoplasm 6.Antennapedia is an homeotic transcription regulator and its homeodomain binds DNA via A. an alpha helix interacting with DNA in major groove B. beta strands interacting with DNA in minor groove C. an alpha helix interacting with DNA in minor groove D. beta strands interacting with DNA in major groove
