Cell Division Flashcards
Cell cycle
Divides Rep of cells genetic matrial At of ends of sphase twice as much Copy is chromatid 2 chromosomes have struc of centromere
Cell division and mitosis
Multicellular organism
Increase no of cells 2 new daughter cells
Cc
M phase has 2 new daughter cells
1 inherits copy chromosomes
Called mitosis
After s and m starts to rep
Cc
1 inherits copy chromosomes
Called mitosis
After m and s starts to rep
Control of cell division
Cell different tissue
Cells in gut
Replace in gut
Nerve cells are non dividing
Reproduction
Single organism reproduce by cell division
Asexual, only single parent and more complex. Plants are a sexual
Gametoggenesis
Silo mature
DNA duplicated in mitosis and meiosis
Mitosis rep chromosomes separates spindle
Meiosis rep chromosomes together as homologous lines up
Mutations
Silent. Coding regions. Same change protein. Inherited. Subsition.
Deletion
Insertation
Mono hybrid inheritance
Offspring are heterogous
Same chacterisic
Dihybrid
Different characteristics
Cross is illustrated
Linkage
Genes are linked
Crossing over
Homologous chromosomes
Fall apart
Fingerprinting
DNA has same Sequence
