Question
For each of the following statements about translation, choose if it is true for eukaryotes only, bacteria only, or both eukaryotes and bacteria.
Eukaryotes only
Bacteria only
Both Eukaryotes and Bacteri
Ribosome has a 60S subunit and a 40S subunit (80S total).
A Shine-Dalgarno consensus sequence is required for the attachment of the mRNA to the ribosome.
Uses initiation factors, elongation factors, and release factors during translation.
The ribosome attaches to the mRNA using proteins that interact with the 5' cap and the poly(A) tail of the mRNA.
A Kozak consensus sequence helps the ribosome identify the correct initation codon.
Ribosome has a 50S subunit and a 30S subunit (70S total).
The first AUG encodes N-formylmethionine.
During elongation, charged tRNAs enter the A site of the ribosome, a peptide bond is formed between amino acids in the A and P sites, and the ribsosome translocates along the mRNA to the next codon.
Each mRNA may be simultaneously translated by several ribosomes, producing a structure called a polyribosome.
Transcription and translation occur simultaneously.
A.Eukaryotes only
B.Bacteria only
C.Both Eukaryotes and Bacteri
