DNA Adenine Thymine Guanine Cytosine Nitrogen
bases Mutation/alteration synthesis
|
DNA is a large molecule composed of 4 nitrogen bases – A,T,G,C. |
|
The information stored in DNA is used to direct the synthesis of proteins required by the cell. |
|
Topic: The Genetic
Code |
|
The sequence of bases on DNA determines the sequence of amino acids in the protein molecule produces. |
|
Any alteration in the DNA sequence is a mutation. The alteration is passed to all cell derived from the mutated cell. |

Enduring Understanding (s): An organisms characteristics are determined by its DNA. Offspring resemble their parents because they inherit similar genes that code for the production for proteins that form similar structures and do similar functions.
Essential Question (s): Why do children often resemble their
parents? Why does a genetic mutation
cause such a significant change in the structure or function of an
organism?
