Cancer |
Uncontrolled cell growth |
|
Benign |
"non cancerous" growth- remains in tissue of origin |
|
Malignant |
cancerous, is able to spread from tissue of origin into another tissue type |
|
MPF= Mitosis promoting facor |
2 proteins: cyclin & cyclin dependent Kinase Cyclin levels are extremely low at the beginning of cell cycle as it is produced, attached to MPF and is phosphorylated which inactivates it At the end of G2 (MPF) are very high |
|
Activated MPF |
-triggers prophase -causes centrioles to dissemble cytoskeleton, creates spindle fibers -causes the nuclear membrane to disintegrate |
|
Meiosis |
-cell replication of the gametes(sex cells) -end product: 4 haploid daughter that are all genetically different -function: reduce # of chromosome in half, create genetic varation |
|
Haploid |
1 copy of every chromosome |
|
Diploid |
2 copies of every chromosome |
|
Egg(haploid) |
23 chromosomes |
|
Sperm(haploid) |
23 chromosomes |
|
Homogenous chromosomes |
matching chromosomes made of the same gene type |
|
Tetreid |
2 homologs pair up at chiasma |
|
Chiasma |
point of connection between homologs |
|
Crossing over |
exchange of genes between non-sister chromatids |
