Amino acid attaches at which site of RNA:
Correct answer: C. 3'-site with terminal OH
- A. Anticodon site
- B. Ribosomes recognition site
- C. 3'-site with terminal OH
- D. Activation enzyme recognition site
Explanation
[A] At anticodon site is complementary to a corresponding codon in mRNA and binds to that specific complementary codons[B] Ribosome recognition site plays an important role in translational initiation [C] Amino acids are attached to the tRNA 3'-end as a prerequisite for entering the ribosome for protein synthesis.[D] Activation enzyme site is imp for binding of speecfic enzymes required for translation

About Ribonucleic Acid (RNA)
Ribonucleic acid is generally a single-stranded nucleic acid containing ribose and uracil instead of thymine. Coverage includes mRNA, tRNA and rRNA, complementary base pairing, transcription and translation, and the differences between RNA and DNA in structure, location and biological function.
