Reproduction
one parents
offspeing genetically identical to the parent
asexual
two parents
offspring not identical to parent
sexual
found in nucleus
contains code for organism genes
DNA
thin twisted from DNA
dna takes when cell is resting
chromatin
rod shaped structures of DNA
formed during cell divison
a chromosome may be single or double stranded
chromosomes
one strand of a double stranded chromosome and each one is identical
chromatids
region of attachment between two chromatids
centromere
why does asexual use the process of mitosis?
to make genetically identical cells
the process of cell division that produces 2 identical daughter cells
mitosis
O<-- 10 ----> 0--> 10 --> O ---> 10
parent cells have to produce identical daughter cells with the same #
resting phase
non dividing stage
identical copies
interphase
chromosomes are visible and *replicated*
asters (around centrioles) are long and spindle fibers form
prophase
chromosomes at equator
asters are at the poles
spindle spans between asters
metaphase (EQUATOR)
spindle *separates* chromatids and pulls them to poles
anaphase (away stage)
2 identical daughter cells divided by cell plate
telophase (two cell stage)
use IPMAT
animal amd plant
use mitosis for growth and repair
plant and animal
no aster
no centrioles
animal
form a cell plate to divide cytoplasm
plant
a diease of uncontrolled cell divison of abnormal cells
cancer
cancer causes
genetic link
enviodnment link
infectious agents
treatment for cancer
sugery
chemotherapy
radiation
prevention of cancer
live a healthy life
prevent use of radiation and drugs
trade off
DNA located at the end of chromosomes
controls number of cell divisons
shortens with every cell divison
when runs out cell stops dividing
telomeres
