Protein Synthesis
In the nucleus
-
DNA is split by DNA helicase
-
as it is split, free nucleotides bind to the exposed bases of the NON-CODING
STRAND (this is because it is complementary – it is the opposite of what will be
on the tRNA – which is the actual amino acid)
-
this process is helped by RNA polymerase
-
the nucleotides join together to form mRNA (messenger RNA)
-
the DNA closes back together
-
the mRNA formed is then spliced:
o in this process, the introns (which are NON-CODING) are removed
o the exons (which are CODING) are kept
