How would a change in the sequence of
nucleotides in a DNA molecule affect the
mRNA transcribed from the DNA molecule?
Any change in the DNA would cause a
change in the mRNA molecule
The diagram below shows a codon chart. A codon
chart shows which codons code for which amino acids.
This chart shows the amino acids coded for by each
of the 64 possible mRNA codons. To find which
amino acid the codon CAA codes for, follow these
steps. (1) Look on the left side of the chart to
find the large row of codons that begin with C. (2)
Move across this row until you get to the column of
codons whose second
base is A. (3) Move
down this column until
you get to the row of
codons whose third
base is A. The codon
CAA codes for the
amino acid glutamine.
Suppose a DNA
mutation led to a
change in a single
mRNA codon. Now
suppose this codon
changed from GCC
to GCG.
By looking at the codon chart, you can see that
both of these codons code for the amino acid
alanine. So even though the DNA and mRNA have
changed, there is no change in the protein!

folded sheet,
start at one of the

the fold between the
two marks.
Take the cut sheet
from step 3 and
fold it like a
