How many sites in the large subunit of the ribosome are available for subsequent amino acids to bind to during translation?
Options
- AOne
- BTwo
- CThree
- DFour
Correct answer
B. Two
Step-by-step solution
The cellular factory responsible for synthesizing proteins is the ribosome. The ribosome consists of structural RNAs and about 80 different proteins. In its inactive state, it exists as two subunits; a large subunit and a small subunit. When the small subunit encounters an mRNA, the process of translation of the mRNA to protein begins. There are two sites in the large subunit, for subsequent amino acids to bind to and thus, be close enough to each other for the formation of a peptide bond. The ribosome also acts as
