Protein Introduction


Objective: DNA is an organic compound that contains genetic information that is written in the "language of life".  You need to understand the components that make up DNA molecules, and how information is coded.  In other words, you must be "fluent" with the "language of life" and tell what it all means.

Specifically, be able to...


Label the components of a nucleotide


Distinguish a DNA molecule from a RNA molecule


Explain DNA replication


Transcribe a strand of DNA onto mRNA


Apply the mRNA code to translate mRNA, listing the sequence of amino acids


 Find and classify mutations from altered amino acid sequences
