Definition
tRNA (transfer RNA) functions in translation by transporting specific amino acids to the ribosome, where it pairs with corresponding codons on the mRNA (messenger RNA) strand, facilitating the synthesis of polypeptides. The ribosome acts as a molecular machine that orchestrates the decoding of mRNA and the assembly of amino acids into a protein chain.
Summary
tRNA and ribosomes play crucial roles in the process of translation, which is the synthesis of proteins from mRNA. tRNA molecules transport specific amino acids to the ribosome, where the ribosome reads the mRNA sequence and assembles the amino acids in the correct order to form a protein. This process is essential for cellular function and the expression of genetic information. Understanding how tRNA and ribosomes work together helps us grasp the fundamental mechanisms of biology. This knowledge is not only vital for studying genetics and molecular biology but also has practical applications in fields like biotechnology and medicine, where manipulating protein synthesis can lead to innovative treatments and technologies.
