Question 1 (1 point) Initiation of translation always starts with the large subunit of the ribosome binding to the mRNA first. both subunits of the ribosome binding to the mRNA together. an amino acid binding to the mRNA first. the small subunit of the ribosome binding to the mRNA first. Question 2 (1 point) Initiation of translation is dependent on the presence of ________ in eukaryotes. a TATA box a 5' methylated G-cap a Shine-Dalgarno sequence a 3' poly A-tail Question 3 (1 point) The Shine-Dalgarno sequence is used in initiation of translation in eukaryotes. termination of translation in prokaryotes. termination of translation in eukaryotes.

Step 1
So the answer is: $\boxed{\text{the small subunit of the ribosome binding to the mRNA first}}$ For Question 2, initiation of translation in eukaryotes is dependent on the presence of a 5' methylated G-cap. So the answer is: Show more…

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

A significant difference between prokaryotes and eukaryotes in the initiation of translation is that: 1. GTP hydrolysis is required for prokaryotic initiation, but not eukaryotic initiation. 2. In prokaryotes, the large subunit of the ribosome binds after the mRNA; in eukaryotes, the large subunit binds before the mRNA. 3. In prokaryotes, base-pairing between the mRNA and an rRNA determines which start codon to use; in eukaryotes, the small subunit begins scanning the mRNA at the 5' cap until it reaches the first start codon. 4. Many more initiation factors are required for prokaryotes than for eukaryotes.
