Rb pathway Gel electrophoresis PCR Neuralation (embryo development) pt. 1 Neuralation (embryo development) pt. 2
100
What is e2f
A common protoncogene
100
What is farther toward the positive end of the plate
Smaller fragments move
100
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
100
What is Ectoderm, mesoderm, endoderm
The 3 parts of the early embryo
100
What is The neural tube
Made of Ectodermal cells - will become the central nervous system
200
What is Rb
Natuaral inhibitor of e2f
200
What is DNA ladder
helps us count number of base pairs
200
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
200
What is endoderm
goes on to be cells of the intestine lining and airway lining
200
What is Notochord
made of mesodermal cells that release noggin
300
What is adding phosphates
way to turn off Rb
300
What is Negative
DNA has this charge
300
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
300
What is Neural
default state of the ectoderm
300
What is neural
noggin is present cell will become
400
What is Genes always being expressed and moving from G1 to S when they are not supposed to
mutant Rb causes
400
What is Wells
Holes in agar plate
400
What is DNA, nucleotides, tach pol, primers, (maybe dntps unclear notes on this)
Starting material for PCR
400
What is noggin
Helps change from default to something else
400
What is Skin
BMP4 present cell will become
500
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
500
What is phosphodiester bonds
Bonds that NEVER break in PCR
500
What is Noggin
highly concentrated close to the notochord
500
What is Pluripotent
What is the cell fate at gastrolation
