What molecule catalyzes the formation of proteins?
a.) tRNA
b.) ribsomal proteins
c.) rRNA
The protein synthesis process is a process where amino acids are formed by reading the frame of the RNA chain. The process starts at the position of the initiation codon 'AUG' that codes methionine amino acid. This a chemical reaction that uses the stored energy of adenosine triphosphate to form the peptide bond. Ribosomes are used as a catalyzing agent in this reaction.
The ribosomal RNA catalyzes the peptide bond formation and growth of the polypeptide chain. The ribosomal RNA form the ribosomes of larger subunit where the protein synthesis takes place. Hence, (c) is the correct answer.
tRNA or transfer RNA carries the amino acid molecules by charging step of tRNA with the help of adenosine triphosphate. This charged or high energy is being transferred to form the peptide bond inside the ribosome formed by the rRNA molecule. Hence, option (a) is incorrect.
Ribosomal proteins are mainly eukaryotic proteins that interact with the ribosomal RNA molecules to form enough subunits of the ribosome to perform the translation process. Hence, option (b) is incorrect.
