How are mRNA and tRNA used in protein synthesis within a cell?

Posted April 19, 2024


Answer

mRNA carries genetic information from the DNA in the cell's nucleus to the ribosomes in the cytoplasm. At the ribosomes, the genetic information encoded in the mRNA is translated into a specific sequence of amino acids to form a protein. tRNA plays a crucial role in protein synthesis by transporting specific amino acids to the ribosome. Each tRNA molecule is linked to a specific amino acid, and its anticodon sequence pairs with the codon sequence on the mRNA, ensuring that the correct amino acid is added to the growing protein chain.
