Transcription Vs. Translation KEY
Objective: Differentiate between the processes and products of transcription and translation.
Transcription
Translation
Purpose
Make a copy of the genetic code
contained in the DNA sequence
into mRNA which can leave the
nucleus.
Synthesize proteins using the
genetic code copied from the
DNA in the nucleus by the
mRNA stand.
Process
Enzymes transcribe or copy
one strand of the DNA into a
single-stranded mRNA
molecule. These enzymes
bind the following bases to
form the mRNA strand:
U binds with A, A binds with
T, C binds with G, and G
binds with C.
mRNA binds to a ribosome,
and tRNA brings in an amino
acid and anticodon to build
the amino acid chain
(polypeptide chain or protein).
Location in Cell
Occurs in the nucleus
Occurs in the cytoplasm
End Product
End product is a strand of
mRNA.
End product is a protein
molecule.
