100

What is a ligand 

A chemical messenger that binds to the receptor 

100

What happens during the S phase of the cell cycle 

DNA synthesis/replication

100
T/F all cells have different DNA to produce different proteins 

False 

100

Where does Spermatogenesis and Oogenesis occur?

Testes and Ovaries 

200

What are the two proteins in eukaryotic transcription that Enhance transcription or Inhibit transcription 

Activator Proteins and Repressor Proteins

200

T/F a lipid insoluble ligand can bind to intracellular receptor 

False 

200
What phase during mitosis are chromosomes lying along the midline attached to spindles for separation 

Metaphase 

200

What is the developmental process that kills cells.

Example: Removing webbing between fingers

Apoptosis (Programed Cell Death)

200

What structure in the brain releases LH and FSH to the gonads 

Anterior Pituitary 

300

How can DNA wrap tightly around histone proteins 

DNA is negative charged Histone proteins positive 

300

What is the name of the receptor that is a dimer and when active is phosphorylated 

Enzyme Linked (RTK)

300

What Gene is activated when DNA is damaged at the G1 check point 

p53 tumor suppressor 

300

Morphogens set up what in development

Axes (anterior and posterior)

300
A spike in what hormone causes the release of the egg in the menstrual cycle 

LH I will take Estradiol too if you explain why 

400

What does the TBFII protein do in transcription?

Binds the RNA polymerase II to the Promoter region 

400

When a G-protein is off what is bound to the protein?

GDP 
400

What is dimer that peaks at the beginning of the M-phase 

MPF

400

Hox genes allow for what to be set up during development

Segmentation and identity (Abdomen, Head, Hands, Legs) 

400

Progesterone does what to LH and FSH hormones 

Negative feedback (Inhibits) 

500

We want to transcribe DNA to make a protein what is one method we can decondense Chromatin 

Acetylation or Chromosome Remodeling complex  

500

What is the role of cAMP and what does it bind to

Secondary messenger that binds to Kinases

500

What is the Oncogene that produces a mutated protein that permanently binds GTP 

Ras 

500

What is the name of the Hox gene mutation that allows for multiple appendages 

Example: Fly with 3 wings 

Homeotic 

500

What mechanism does Birth control pills use to prevent pregnancy 

Synthetic version of progesterone and estradiol suppresses the release of GnRH, FSH, and LH from the Anterior pituitary. Prevents Ovulation.
