To verify that you understand the relationship between
DNA, RNA and proteins, you will complete the following
- Print out Activity 3 Worksheet in Show Your Stuff.
Write out the complementary mRNA nucleotide sequences
that correspond to the first 45 bases of each DNA strand
in the space provided on the worksheet. Separate
nucleotides into discrete codons.
- Use the codon/amino acid chart in Access
Excellence to determine the sequence of the first 15
amino acids in each protein molecule coded for by the
- In general terms, explain how the proteins that
result from the translation of the two genes will differ
from one another-address size, number and sequence of
amino acids, and why they would have different chemical
properties. Check out the shapes of some different
(this page has several different proteins--select GIF to
see diagrams of them).
