Flashcards in Mitosis & Meiosis Deck (41):
Stages of mitosis
Interphase (3 parts- g1, S, g2), prophase, metaphase, anaphase, telophase and cytokinesis
Mitosis - Site of process
Somatic cells (body cells)
Meiosis- site of process
Gonad cells (sex cells)
Mitosis- are parents cells haploid or diploid?
Meiosis- a parent cells diploid or haploid?
Mitosis-Chromosome replication occurs
Meiosis - chromosome replication occurs?
Mitosis - line up in homologous pairs?
Meiosis- line up in homologous pairs?
Yes metaphase 1
Mitosis- spindle fibres pulp chromosomes apart?
Meiosis- spindle fibres pull chromosomes apart?
Yes anaphase 2
Mitosis- number of daughter cells?
Meiosis - number of daughter cells?
Mitosis- daughter cells are haploid or diploid?
Meiosis - daughter cells are haploid or diploid?
What are the two types of cell division?
Mitosis and meiosis
Where in interphase do the chromosomes replicate?
Stages of mitosis- interphase
G1,S,G2 chromosome replicate to have two chromatids
Stages of mitosis- prophase
Chromosomes and their chromatids become visible
Stages of mitosis- metaphase
Replicated chromosomes line up on the equator of the cells
Stages of mitosis- anaphase
the chromatids seperate and move to different sides of the cells
Stages of mitosis- telophase
Two nuclei form, both with the same number of chromosomes as the parent cell
Stages of mitosis- cytokinesis
Cell membranes form making two daughter cells, each with a nucleus
Stages of meiosis- metaphase 1
Replicated chromosomes form homologous pairs, attached to spindle fibres and line up in the middle
Stages of meiosis- anaphase 1
One replicated chromosome of each pair move to opposite poles
Stages of meiosis- telophase 1
Two cells are formed, each with one replicated chromosomes
Stages of meiosis- metaphase 2
Chromosomes line up on the equator attached to spindle fibres
Stages of meiosis- anaphase 2
Chromatids seperate and move to poles
Stages of meiosis- telophase 2
Four cells result with one copy of each chromosome, haploid gametes
Difference between haploid and diploid cells
Haploid cells have half the number of chromosomes as a diploid cells (N). Diploid cells contain a full set of chromosomes (2n).
What are gametes? Are they haploid or diploid?
They are the sex cells ( egg and sperm). They are haploid
What are somatic cells? Are they diploid or haploid cells?
Somatic cells are body cells. They are diploid.
Difference between mitosis and meiosis
Mitosis is the reproduction of body cells and there daughter cells contain a full set of chromosomes. Meiosis is the reproduction of gonad cells and there daughter cells are haploid cells
Define DNA replication
DNA replication is the copying of DNA resulting in two strands of DNA
One of the strands of a chromosome after replication
The cell division that produces two daughter cells identical to the parent cell
Define asexual reproduction
Is where the offspring produced using mitosis without any union of gametes
Define homologous chromosome
Chromosomes with genes for certain characteristics at the same location
The type of cell division that produces cells with half the number of chromosomes as the parent cell
Define sexual reproduction
The production of new organisms by combing the genetic information of two organisms
