Rb pathway | Gel electrophoresis | PCR | Neuralation (embryo development) pt. 1 | Neuralation (embryo development) pt. 2 |
---|---|---|---|---|
What is e2f
A common protoncogene
|
What is farther toward the positive end of the plate
Smaller fragments move
|
What is dénaturation, 95 degrees, hydrogen bonds break, and dna is split into 2 strands (unzipped)
Step one of PCR
State name, temp, bonds made/broken, and what happens |
What is Ectoderm, mesoderm, endoderm
The 3 parts of the early embryo
|
What is The neural tube
Made of Ectodermal cells - will become the central nervous system
|
What is Rb
Natuaral inhibitor of e2f
|
What is DNA ladder
helps us count number of base pairs
|
What is Anealing, very cold (55), primers are bonded to DNA where we want to amplify, Hydrogen bonds are formed
Step 2 of PCR
State name, temp, bonds made/broken, and what happens |
What is endoderm
goes on to be cells of the intestine lining and airway lining
|
What is Notochord
made of mesodermal cells that release noggin
|
What is adding phosphates
way to turn off Rb
|
What is Negative
DNA has this charge
|
What is synthesis (intermediate temp)
Tach pol uses nucleotides to build new dna, H bonds form, dntps are used by enzymes, and phosphodiester bonds form
Step 3 of PCR
State name, temp, bonds made/broken, and what happens |
What is Neural
default state of the ectoderm
|
What is neural
noggin is present cell will become
|
What is Genes always being expressed and moving from G1 to S when they are not supposed to
mutant Rb causes
|
What is Wells
Holes in agar plate
|
What is DNA, nucleotides, tach pol, primers, (maybe dntps unclear notes on this)
Starting material for PCR
|
What is noggin
Helps change from default to something else
|
What is Skin
BMP4 present cell will become
|
Binds to a promoter on a sequence of dna and recruits rna pol and the gene immediately following that promoter is transcribed
how does e2f work
|
What is phosphodiester bonds
Bonds that NEVER break in PCR
|
What is Noggin
highly concentrated close to the notochord
|
What is Pluripotent
What is the cell fate at gastrolation
|
