Question

13) Among the following statements, which one IS CORRECT regarding ribosome and translation?

A. The release factor is an empty tRNA which binds to A site to terminate translation
B. The charged tRNAs enter from A site then translocated to the P site during elongation
C. During initiation, the large ribosomal subunit binds first to the mRNA, then the small subunit and then the initiator tRNA
D. The initiator tRNA first binds in the A site of the ribosome then it is translocated to the P site during elongation

Answer 1

Answer:

Ribosomes exist in the cytoplasm in prokaryotes and in the cytoplasm and on rough endoplasmic reticulum membranes in eukaryotes. Mitochondria and chloroplasts also have their own ribosomes, and these look more similar to prokaryotic ribosomes (and have similar drug sensitivities) than the cytoplasmic ribosomes. Ribosomes dissociate into large and small subunits when they are not synthesizing proteins and reassociate during the initiation of translation.E. coli have a 30S small subunit and a 50S large subunit, for a total of 70S when assembled (recall that Svedberg units are not additive). Mammalian ribosomes have a small 40S subunit and a large 60S subunit, for a total of 80S. The small subunit is responsible for binding the mRNA template, whereas the large subunit sequentially binds tRNAs.
