Which type of RNA shows enzymatic activity by catalyzing peptide bond formation between amino acids?
A) mRNA
B) tRNA
C) rRNA
D) all types of RNA
E) no RNA shows enzymatic activity
Enzymatic Activity
The catalytic action of enzymes in facilitating biochemical reactions without being consumed in the process.
Peptide Bond
A covalent bond formed between amino acids during the synthesis of proteins.
rRNA
Ribosomal RNA, a type of RNA that, together with proteins, makes up the ribosomes, where protein synthesis occurs.

Final Answer :
C
Explanation :
rRNA (ribosomal RNA) has been shown to have enzymatic activity and is responsible for catalyzing peptide bond formation between amino acids during protein synthesis. mRNA (messenger RNA) carries the genetic information from DNA to the ribosome, and tRNA (transfer RNA) delivers the amino acids to the ribosome, but neither of these types of RNA has enzymatic activity. Therefore, the correct answer is (C) rRNA.
