Investigating Enzymes

Today we spent the first half of class completing the investigating enzymes lab.  Tomorrow you will collect the data and we will discuss experimental design.  On Saturday you will have a test.

What's going to be on the test? You spent the second half of the lab working in groups to review what we have learned since the first test.  Here's some of the things that you came up with:


Lab:
Gel Electrophoresis - placed in wells, the PO4 group is negatively charged so when you run an electric current through it the (starting at the negative side) the DNA segments move towards the positive side. Smaller pieces of DNA move to the positive side of the gel more quickly.

DNA Extraction

Articles:
William's Syndrome (lack of trust)
Stathmin & Timid Mice (fear)
Sports Gene - gene is ACTN3 and the protein is Alpha Actinin.  The traits are fast twitch or endurance.


Vocab and Concepts:
Chromosomes (homologous chromosomes)
Loci
Allele
Genotype
Phenotype
Recessive
Dominant
Punnet Square
Restriction Enzymes
Protein shape (how to build a protein)
Plasmids
Functions of proteins (for example receptors - PTC)
Homozygous and Heterozygous



An important note about dominance and recessive:  Read this article to help you understand what dominant and recessive really means.
