MatchList IwithList II
| List I (Binding site of ribosome) | List II (Substances associated) |
|---|---|
| (A). P-site | (I). Amino-acetyl tRNA |
| (B). A-site | (II). Peptidyl tRNA |
| (C). E-site | (III). Exit |
Choose thecorrectanswer from the options given below:
Options:
Answer:
B
Solution:
The ribosome has three binding sites for tRNA during translation:
The P-site (peptidyl site) holds the tRNA carrying the growing polypeptide chain. Thus, (A) matches with (II).
The A-site (aminoacyl site) holds the tRNA carrying the next amino acid to be added to the chain. Thus, (B) matches with (I).
The E-site (exit site) is where discharged tRNAs leave the ribosome. Thus, (C) matches with (III).
The correct matching is (A) - (II), (B) - (I), (C) - (III).
Answer: (A) - (II), (B) - (I), (C) - (III)
