Test This Thursday

Hi All,

I wanted to give you a reminder about what to expect on the test this coming Thursday, February 28. If some of you missed school this week, please get back up to speed ASAP. So what's on the test? The following:

1. Cell Theory
2. The basic organelles of the animal cell, as detailed in the ANIMAL CELL THEATER, and how they work together in the functioning of a cell
3. The basic differences between the organelles in plant and animal cells
4. Information on chromosomes in the nucleus of human cells (22 number pairs + the XX or XY = 23 pairs or 46 total chromosomes)
5. Dominant and recessive traits (more to come this week)
6. DNA - sugar and phosphate backbone, nucleic acid bases (adenine, thymine, cytosine, guanine)
7. The importance of the Y chromosome in males, mitchondrial DNA in females, and how mutations (markers) enable us to trace our ancestors from east Africa to where we are today.

I think that is enough. Please email me with any clarifying questions that you have about this information, or bring them to class on Monday. If you are missing notes, please check in with a classmate ASAP.
