In which process does the transfer of genetic information occur?

Which of the following $RNAs$ is not required for the synthesis of protein?

Which of the following characteristics is not applicable to $tRNA$?

The sequential events that occur during protein synthesis are:

If a certain group of cells utilizes the amino acid glycine exclusively for protein synthesis,and if a growing culture of these cells is fed radioactive glycine,radioactivity will be found first in the

$A$: Peptidyl transfer site is contributed by the larger subunit of the ribosome.
$R$: The enzyme peptidyl transferase is contributed by both $23S$ and $16S$ ribosomal subunits.
