What is transcription?

First stage of protein synthesis

1 of 6

Describe the start of transcription

RNA polymerase ataches to the DNA double-helix. Hydrogen bonds between DNA strands break, seperating strands, DNA molecule uncoils. Makes a template to make a mRNA copy. RNA polymerase lines up free RNA nucleotides alongside the template strand.

Describe the rest of transcription

RNA nucleotides pair with bases, forms mRNA. RNA moves along the DNA seperating them and reassembling mRNA. h20 bonds reform. Moves out through nuclear pore

What is translation

Second stage of protein synthesis

4 of 6

Describe the start of translation

Translation takes place on the ribosomes in the cytoplasm, or found on the rough Endoplasmic Reticulum (ER)the ribosomes are the sites of protein synthesis, the mRNA strand attaches to a ribosome

5 of 6

Describe the rest of transcription

tRNA molecules transport specific amino acids to the ribosome each mRNA codon codes for a specific amino acid the anti-codons and codons match up and form base pairs peptide bonds form between the adjacent amino acids to form the polypeptide (prote
