tRNA
Q1: Where is tRNA located?
Answer:
Transfer RNA is present in the cytoplasm of the cell.
Q2: What does it mean when tRNA is charged?
Answer:
tRNA carries amino acid on its arm and transfers it to the A site. tRNA carrying amino acids is known as changed tRNA.
Q3: What is the function of tRNA?
Answer:
tRNA has dual functions, first, it reads the codons and second, it binds with specific amino acids.
tRNA – the Adapter Molecule
tRNA is also known as transfer RNA is a subtype of RNA, tRNA help in the protein synthesis process. tRNA carries the amino acid to the ribosome, which is the molecular machine that assembles the protein, and ensures that the amino acid is incorporated into the growing protein chain in the correct order. Different types of tRNA present, each with a different sequence and structure allow it to recognize a specific amino acid. Specific amino acids are incorporated in the protein sequence via specific tRNA.
What is RNA?
Ribonucleic acid (RNA) is a single-stranded, non-hereditary (except-retroviruses) molecule that helps in the synthesis of proteins. The nitrogenous bases present in RNA are A (Adenine), U (Uracil), G (Guanine), and C (Cytosine), in which A pairs with U and G with C. The function of ribonucleic acid is to convert genetic information from genes into amino acid sequences of protein. It is classified into three types- messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA) on the basis of the function and molecular size of the nucleic acids.
