Tell the story of DNA replication
*Helicase* unzips double helix at the beginning. *Single-strand binding protein* coat individual strands to prevent re-annealing. They are then fed through replication complex that contains all necessary proteins for replication. *Primase* (RNA polymerase) then constructs short primers on both strands of DNA. Two DNA polymerase molecules then begin building new complementary DNA strands. They are read in the 3' to 5' direction, and build the new strands in 5' to 3' direction. *Sliding Clamp* is a protein that helps keep DNA polymerase tightly associated with the strand. Both enzymes move in opposite direction in the 3' to 5' direction. The enzyme working on the *Lagging Strand* must copy short segments downstream, release from strand, move upstream, and copy another short segment. *Leading Strand* requires only a single primer, while the lagging strand requires multiple primers, one for each of the *Okazaki Fragments*. *RNase H* removes all RNA primers after replication. DNA polymerase then fills in the gaps. *DNA Ligase* creates the last necessary phosphodiester bond.

Non-aggressive models played quietly with non-aggressive toys. Control group with no models Children were then allowed to play in a similar room after watching the models. Those exposed to the aggressive models mimicked the violent behavior toward Bobo, while those exposed to non-aggressive model did not. Boys were more aggressive than girls. Children were more likely to model the behavior of a same-sex model. Girls were more likely to model the aggressive language, and boys were more likely to model the physical violence.

Why is hemophilia more common in males?
Because it is an X-linked recessive disorder. All X-linked recessive disorders are easier for males to get than females because they only need a single "bad X". There is no such thing as a male-carrier for an X-linked disease.
What is repolarization
Because there are more K+ inside the cell (due to Na+/K+ pump), opening of the potassium channels causes K+ to flow out of cell This causes a sudden decrease from +40mV to -70mV
Tell the story of translation
Begins when small subunit attaches __mRNA__ strand at 5' end. Small subunit will begin scanning mRNA until it reaches start codon, AUG. The first __tRNA__, which will always carry methionine, will have the anticodon 3'UAC5' (complements 5'AUG3'. The process up to this point is considered __initiation__. Complete ribosome then begins moving along mRNA strand from 5' to 3'. There are aminoacyl (A), peptidyl (P), and exit (E) sites on the ribosome. New tRNA molecules carrying associate amino acid enter the A site driven by hydrogen bonding. A peptide bond then forms between the amino acid on the new tRNA and amino acid on the previous tRNA, adjacent to the P site. New tRNA shifts over the P site, and previous tRNA moves to the E site, dissociates from the protein, and exits the ribosome. Another new tRNA enters the A site and the process repeats. This process is called __elongation__. Finally at some point the ribosome will reach a stop codon, stimulating a release factor. This process is called __termination__
Describe the process of the menstrual cycle and the hormones involved
Begins with FSH stimulating the maturation of ovum and follicle in the ovary LH then stimulates cells in ovaries to secrete estrogen which signals the uterine wall to proliferate and prepare for potential pregnancy Just before ovulation, a surge in level of estrogen released causes a subsequent surge in levels of LH (Luteal surge), which signals ovulation and development of corpus luteum Corpus luteum then begins secreting estrogen and high levels of progesterone to signal uterine lining to prepare for implantation If no fertilization occurs, corpus luteum degrades and menstrual lining sloughs off If fertilization does occur, corpus luteum continues to secrete estrogen and progesterone, maintaining pregnancy

Describe the role of proline in secondary structure
Causes a kink/turn Usually the first residue at the end of alpha helices, but is rarely found on the inside of the helix Also desirable at the end of beta sheets to make the 180 degree turn to the next row
How is ATP produced by the mitochondria
Cellular respiration starts with glycolysis and results in NADH and FADH2 as the electron carriers. These electrons move down the electron transport chain (series of enzymes on the inner mitochondrial membrane). The H+ ions are then transferred out into the mitochondrial intermembrane space. An increased concentration gradient between the intermembrane space and the matrix forces the electrons through the ATP synthase enzyme channel (into the matrix) The turning of the ATP synthase enzyme results in the phosphorylation of ADP to ATP.

Describe the sliding filament mechanism for muscles
Default low-energy position of myosin heads is bent. Between contractions, ATP hydrolysis provides energy required to straighten these myosin heads into their straight positions They are always attracted to and bind readily with actin (regardless of straight or bent configuration) They are not bound because tropomyosin is covering myosin binding site on actin filament Tropomyosin is clamped down by troponin, and when Ca is released from the SR, it binds to Troponin, releasing the clamp and freeing the binding site The higher energy straight position binds to actin, and relaxes back to bent position: ultimately dragging actin filaments with them (This is the power stroke of contraction) After the power stroke, ATP binds to the myosin head again facilitating it's release from actin filaments; tropomyosin will rebind to binding site and the attached ATP is hydrolyzed providing necessary energy to put the head back in straight position

What is the difference between medical model of disability and social model of disability?
Medical model: Sees the illness or impairment as the problem. The illness or disability is the target of cure and individuals are the passive receivers of services. Diagnosis and treatment is the primary approach Social model: sees the structures within society as the problem. The ill or people with disability are active participants working in partnership with others. Prevention and integration are the primary approach rather than treatment. This approach benefits everyone and pushes society to evolve.

Phenotype is the expression of the gene in terms of its visible or observable characteristics. Genotype refers to the specific alleles held by that individual
Describe phosphorylation and dephosphorylation in regulation
Phosphorylation is catalyzed by protein kinases and works by transferring a phosphoryl group from ATP to another molecule. This will turn the molecule "on" or "off". Dephosphorylation also functions to turn a molecule "on" or "off", but dephosphorylation doesn't usually result in recreating ATP. This is done using phosphatases and releases a free Pi. Phosphorylation and dephosphorylation are NOT reverse reactions
