Question
For each of the following statements about translation, choose if it is true for eukaryotes only, bacteria only, or both e ARibosome has a 60S subunit and a 40S subunit (80S total). B. A Shine-Dalgamo consensus sequence is required for the altachment of the B. Bacteria only A Eukaryotes only mRNA to the ribosome. C. Uses initiation factors, elongation factors, and release factors during A Y The ribosome attaches to the mRNA using proteins that interact with the5 C Both Eukaryotes and Bacteria translation cap and the poly(A) tail of the mRNA. A A Kozak consensus sequence helps the ribosome identify the correct B. Ribosome has a 50S subunit and a 30S subunit (70S total). A. The first AUG encodes N-formylmethionine. C.T During elongation, charged tRNAs enter the A site of the ribosome, a peptide initation codon. 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. B. Transcription and translation occur simultaneously QUESTION 14 uestions and 1 The numbered circles represent amino acids Structures A,BExplanation / Answer
60S and 40S - Eukaryotes only A
Shine Delgarno - Prokaryotes only B
Initiation, elongation and release factors - Both prokaryotes and eukaryotes C
Poly A tail - Eukaryotes only A.
Kozak sequence - Eukaryotes only A.
Ribosomes 50 s and 30 s - Prokaryotes only B.
N formyl methionine - Prokaryotes only B.
A ,E and P sites - Both prokaryotes and eukaryotes B
Polyribosome - Both eukaryotes and Prokaryotes C.
Transcription and translation occurs simultaneously- Prokaryotes only B
