Question
During the elongation phase of translation, the aminoacyl-tRNA carrying the next amino acid to be added to a growing polypeptide chain
in the ribosome, first binds the E site.
in the ribosome, first binds the P site.
binds the ribosome so that its anticodon is positioned in the 30S subunit (in bacteria) to base pair with the matching codon of the mRNA.
never associates with the EF-Tu factors (as this factor only associates with tRNAs that are not charged).
binds to the ribosome so that its anticodon is positioned in the 50S subunit.
A.in the ribosome, first binds the E site.
B.in the ribosome, first binds the P site.
C.binds the ribosome so that its anticodon is positioned in the 30S subunit (in bacteria) to base pair with the matching codon of the mRNA.
D.never associates with the EF-Tu factors (as this factor only associates with tRNAs that are not charged).
E.binds to the ribosome so that its anticodon is positioned in the 50S subunit.
Explanation / Answer
Option C.
Aminoacylated tRNA binds to the smaller subunit of ribosome (30S) to Base pair with the matching codon of the mRNA, this site on larger subunit is called as A site (Aminoacylated site).
At the P site bond formed between two amino acids and at E site tRNA exit the ribosome complex.
But at the beginning of translation, first tRNA binds to P site directly
