Summary Introduction

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

Concept introduction:

The genetic information of DNA is based in the nucleotide base sequences. These sequences are transcribed into mRNA triplets and are called codons. After transcription, mRNA sequences are read by tRNA in the ribosome to synthesize polypeptides and the process is known as translation. tRNA molecules have an anticodon that pairs with its complementary codon during translation. As a result, the codon-specific amino acid comes through the other end of the tRNA. These amino acids form a polypeptide chain.
