To transcribe DNA into mRNA.

To assemble amino acids into a polypeptide chain based on the mRNA sequence.

To replicate DNA prior to cell division.

To transfer mRNA from the nucleus to the ribosome.

To synthesise mRNA from a DNA template.

It binds to the ribosome to facilitate the attachment of amino acids.

It matches with the complementary mRNA codon to ensure the correct amino acid is added.

It synthesises amino acids to add to the polypeptide chain.

It serves as a signal to terminate translation.

It acts as a binding site for mRNA synthesis during transcription.

The ribosome shifts one codon down the mRNA (translocation).

A new tRNA enters the E site.

The polypeptide chain is released from the ribosome.

The ribosome detaches from the mRNA.

A peptide bond forms between the tRNA in the E site and the polypeptide chain.

Provide a site for polypeptide synthesis.

Transport amino acids to the ribosome.

Travel to the ribosome to direct the assembly of polypeptides.

Transcribe DNA.

Translate DNA.
