Cells and such Flashcards
mitosis is done by your body cells. what type of cells do NOT undergo mitosis
sperm cells, and egg cells.
in mitosis the cells that are created are
identical
describe 2 ways that mitosis is important for your body
helps you grow, helps you repair/replace
mitosis is only 10% of the cell cycle if cells were in mitosis more than they were interphase, what would occur.
uncontrolled cell growth = cancer
what is chromosomes made up of
DNA and proteins
mitosis starts and ends with what
diploid cells
how many chromosomes should be in each diploid cells after mitosis?
46
how many chromosomes are in sperm and egg
23 each 46 divided by 2
what would happen if interphsase didnt occur first
Uncontrolled rapid cell growthj
how would you know if two chromosomes were homolugus (father and mother)
same size, same genes in same place
what happens in profase of meiosis during cross over whats the significance
trade geneitic material making recombinant chromosomes, which allows for genitic diversity
meiosis does what twice
PMAT
how would u know if the cells are undergoing metaphase one or metaphase 2
In metaphase 1, the chromosomes are in pairs
describe what occurs during nondisjunction and the effect on the resulting cells
cells dont divide evenly, cells have more or less than 23 chromosomes genetic = disorders
know all stages PMAT
yes
study the meiosis chain
yes
what is mitosis
Mitosis is the process by which a cell divides to form two identical cells, helping with growth, repair, and replacing damaged cells.
what is meiosis
Meiosis is the process by which a cell divides to form four unique sex cells, each with half the number of chromosomes, and is important for sexual reproduction.
how are mitosis and meiosis the same
they r both ways that cells divide both have PMAT both start with one cell and make new cells
how are mitosis and meiosis different
mitosis makes identical cells, meiosis makes diff cells for reproduction
