Mitosis and Cancer

DNA is replicated during the during interphase of the cell cycle

when a cell has become so specialized that it will never reproduce, it enters the phase of the cell cycle.

a chromosome has 2 sister chromatids

is the process where the homologous pairs of chromosomes come together to form a tetrid

cell division takes place during the

the phase of the cell cycle that has primarily for growth , development and specialization is the G1 Phase

the cell prepares for division by growing and reproducing during the G@ phase of the cell cycle

formation of the cell plate occurs during in plant cells

the first phase of mitosis is

chromosomes are captured and moved by a series of microtubulose called the that cross the equator of the cell

the nuclear membrane reforms, chromosomes uncoil and nucleolus reappears during

in animal cells cytokinesis occurs when a protein surrounds the cell and tightens eventually dividing the cell in two

are the root cause of all cancers

genes that keep cancerous cells in check are called suppressor genes

traditional cancer treatments are and by killing rapidly dividing cells

new therapies include activity and the use of that seek out and selctivly destroy malignent cells

5% of cancers are hereditary caused in part by mutations in genes

a is any physical,chemical or biological agent that elevates the risk of cancer

2 viruses associated with increased cancer risks are and

is when blood vessels form around a tumor

the advantage to crossing over is

the first stage of mitosis is where chromatin coils up into dyad chromosomes and the nuclear membrane breaks apart the nucleolus disappears and the spindle starts to form

the 2nd phase of mitosis where the spindle is completed the dyads line up along the metaphase plate

the 3rd phase of mitosis is the centromere holding the two sister chromatids together splits the newly separated chromosomes are pulled to opposite poles of the cell

the 4th phase of mitosis where the chromosomes uncoil the nuclear membrane reforms the nucleolus reappares cytokineses occurs

lines up pairs , separating homogulous pairs and meosis 2 is just like

division reduces the number of chromosomes

Xy is a

XX is a

humans have autosomal pairs, sex chromosomes which is total

in human cells, the N is the number of haploid cells which is 23

in human cells the is 46 diploid cells

cytokinesis in plant cells use a

cytokenisis in animals cells use a protein
