Laboratory Midterm Exam
October 14th and 15th, 2013
Several of these labs had PowerPoint presentations associated with them, as well and they
can be found on EduCAT, along with copies of handouts, etc. that may be useful for study. The
DNA (Deoxyribose Nucleic Acid):
Hereditary molecule that is passed down from parents to offspring
All organisms have the same genetic codes
DNA is the instruction manual for how to build an individual organism
Found in the nucleus of eukaryotic cells

Earths Six Major Extinctions
Periods in Earths history when many species go extinct at the same time, resulting in an
influence in diversity, are classified as mass extinctions (Hallam). Many individua

Interphase: G1, S (replication), G2
Metaphase: Spindle fibers (from the centrioles) pull chromosomes to the center
of the cell
Anaphase: Spindle fibers (from the centrioles) pull chromosomes apart to each

Meiosis: Only happens when sperm and egg cells are being made.
Different from mitosis in that homologous chromosomes divide, not chromatids.
Cells go from Diploid (2n) to Haploid (n)
Homologous Chromosomes: Responsible

Cell Division and Cancer
Stages of Cell Division
Interphase ( most cells in the human body are in this stage):
S-Phase (if there is damage, the cell will go through apoptosis)
G2-Phase (checkpoint to make sure that chromosomes replicated)

We began class with an activity to review the plasma membrane Re:
The plasma membrane is made from phospholipids.
Phospholipids are made from hydrophilic heads (water loving) and hydrophobic tails

Transcription: copies the coding sequence of DNA to the mRNA sequence
No T in RNA it is replaced by U
This nitrogenous base still binds with the A. So, in RNA U=A
When the RNA is made, it is mRNA (messenger RNA

Science begins and ends with questions!
This process occurs in many orders during one single study
Science is MESSY!
