1. To extract and
2. To describe how bases
code for proteins
3. To explain how DNA
was discovered to be
Starter: From last lesson,
remember which base
pairs with which, and
then complete the
% of each base
A sequence of 3 bases is known as a triplet and
codes for 1 amino acid.
The order of the bases in DNA determines the order of amino
acids, which then codes for a protein. **Link to BIOL1
levels of protein structure**
1. Decode these triplets to read a message:
ATG ATA TCT TCC
TCA GCA TAT TCG
2. Then write a message back!
Key Features of the Genetic Code
• It is universal
• It is non-overlapping
• It is degenerate
Complete as many of the 27 terms as you can!
Hint: The glossary is in alphabetical order
1. What do you know now that you didn’t
know 60 mins ago?
2. How could you best demonstrate your
new knowledge about DNA?
3. What do you think we might learn next
