Cell division Flashcards
what are the four stages of mitosis in order
1.prophase 2.metaphase 3.anaphase 4.telophase
what is the difference between plant cell and animal cell cytokinesis?
Animal cells have a cleavage Furrow and plant cells have a cell plate.
what type of asexual reproduction occurs in prokaryotes
binary fission
what is the difference between mitosis and cytokinesis
Mitosis is the division of nucleus. in cytokinesis is the division of cytoplasm.
what must happen to DNA before mitosis occurs
growth and a copy of itself
where do sister chromatids connect to each other to form a chromosome
centromeres
what is the final result of prophase
mitotic spindle fibers finishes forming between centrioles and chromosomes.
what is the final result of metaphase
chromosomes are aligned at the metaphase plate of the equator of the cell.
what is the final result of anaphase
sister chromatids go to the middle of the cell
what is the final result of telophase
the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells.
what does a cell check for at the G1 checkpoint
decides whether or not to proceed with division based on factors
what does a cell check for at G2 checkpoint
ensures that all the chromosomes have been replicated.
what does a cell check for at the mitosis checkpoint
the cell examines whether sister chromatids are correctly attached to the spindle microtubes.
what are three reasons cells undergo mitosis
- development of growth
- cell replacement
- asexual reproduction
what happens to the chromosomes after a cell undergoes mitotic cell division
the cell duplicates its chromosomes
a normal body cell of a fruit fly contains eight chromosomes each normal gamete of this organism contains
reproduction and development
how are mitosis and meiosis similar how do they differ
mitosis has two diploid somatic cells. meiosis has four haploid gametes
during sexual reproduction why are the process of spermatogenesis and oogenesis and fertilization that serve food genetically healthy offspring
because sexual reproduction has the potential to produce tremendous variation in The Offspring.
changes to the genetic code of a human can be transmitted to The Offspring only if they occur and what type of cells
sperm cells
how do you determine if chromosomes are homologous
if two chromosomes have the same size.
how does crossing over affect the genetic diversity
because the two chromosomes are exchanging DNA
play photograph of a human chromosomes that may be studied to determine possible genetic disorders is known as a
karyotype
what type of reproduction results in the greatest degree of genetic variation in offspring
sexual reproduction
in animals the process which results in a haploid gametes is known as
meiosis
what two type of gametes are formed as a result of meiosis.
sperm and egg cell
I want to carry a types of male and female different from one another
female XX chromosome
male XY chromosomes
