Summary Introduction

To explain: The function of tRNAs in building polypeptides in the context of the ribosome.

Introduction:

DNA contains genetic information which is encoded in nucleotide base sequences. These sequences are transcribed into mRNA codons and are then translated into polypeptides by tRNA molecules in the ribosome. During translation, the codon of the mRNA sequence is paired with its complementary anticodon of the tRNA, and the codon-specific amino acid is delivered to the other end of the tRNA. The amino acids are then linked together to form the polypeptide chain.
