Steps
in Protein Synthesis - 3
DNA transcription: (cont=d)
“ when the exon is activated a copy is made in
the form
of mRNA through the
process of transcription
Translation:
“ mRNA
carries units of 3 bases (triplets) and are these triplets are called codons
“ the codon
specifies the order of amino acids thus the protein formed
“ there are
20 amino acids used to make up proteins
“ there are 4
nucleotides (A, G, T, C of DNA) (and U of RNA) which results in 64 different codon
possibilities
