

Gene –
Chromosome –
1 molecule of DNA = 1 chromosome
What are the building blocks of DNA?
What are the building blocks of protein?
How do genes code for genetic traits?

Answer:
1 gene  code for  one protein!

Examples:



Eye color
Hair color
Normal Blood clotting vs. hemophilia
We know how the code works!

CCCGATATTACGCTTAGGTACCGTC
