Mendel
Mendels three laws
Dominance
Segregation
Independent Assortment
What is Meiosis?
Germ cells/ 1/2 cell
What is Mitosis?
Cell body
2 identical cells
g1 phase
singling factors
growth factors
cell division
is the cell big enough?
Does it have the right nutrition
What is tissue renewal
Dividing bone marrow cells
Law of Independent Assortment is
One gene doesn't affect the other gene
Meiosis cell cycle
2 rounds of mitosis
Prophase 1
metaphase 1
Anaphase 1
Telophase 1
Meiosis II
Prophase II
Metaphase II
Anaphase II
Telophase II
What is binary fission?
-DNA replication
-DNA segregation
-Cytokinesis- cell elongates
---mother cell-> two daughter cells
s phase
Monitored by P53
DNA damaged checkpoint
turns on genes
Activates cell, stabilizes
What phase is the segregation of chromosomes happen?
Telophase
What is the difference between segregation and dominance
Segregation is two allées placed in separate gametes- meiosis
(alleles for different traits segregate independently during the formation of gametes, ensuring genetic variation.)- google
Dominance- When two alleles are present, one is dominant and one doesn't show- mitosis
What are the gender chromosomes
male-y
Mitosis cell cycle
Interphase - cell grows
Interphase
Prophase
Metaphase
Anaphase
Telophase
g2 phase
cell growth
protein synthesis
Preparation for mitosis
How many autosomes
46 chromosomes
44 autosomes
22 pairs
Who is Mendel
Monk
Mid 1800's
Worked with pea plants
Father of genetics
Why are human's diploid organisms
have to copies of every chromosome
What is cytokinesis
Cytoplasm division
How many checkpoints are there?
3
RB is ?
retina blastoma
e2f- activator, transcription, binds to promote
Theory of Inheritance
You inherit traits from your parents
How many rounds are there in meiosis?
2
What phase is the spindle formed
Pro metaphase
What are the 4 cyclin and what does it do
D
E
A
B
all have a CDK,
tell the CDK to phosphorylate
What happens when P53 is not working correctly
cells gain multiple mutation
can lead to cancer at a young age
