In animals, somatic cell are produced by mitosis and ______ are produced by meiosis.
Gametes
Clones
Zygotes
Spores
"The cell's DNA replicates', This event occurs in cell cycle during ______
M phase
G1 phase
S phase
G2 phase
At the following of cell division the chromosome composed of two chromatid,
The G1 phase of the mitotic cycle
Late anaphase of mitosis
Late anaphase 2 of meiosis
Telophase 1 one meiosis
How does mitosis in plant cells differ from that in animal cell?
Animal cells does not form spindle
Animal cells lack of cytokinesis
Plant cell lacks of cell plate
Plant cell lacks of centrioles
The phase of cell division in which the nuclear envelope and nucleolus are disappearing as the spindle fibers are appearing is called
Metaphase
Telophase
Anaphase
Prophase
All of the following occur during prophase of mitosis in animal cells EXCEPT
The centrioles move toward opposite poles
Chromosomes are duplicated
The nucleolus can no longer be seen
The spindle is organized
The containing 92 chromatid at metaphase of mitosis would, at its completion, produce two nuclei containing how many chromosomes on each of them?
12
16
23
46
Cytokinesis usually, but not always, follows mitosis. If a cell completed mitosis but not cytokinesis, the result would be a cell with
A single large nucleus
High concentration of actin and myosin
Two nuclei
Two nuclei but half the amount of DNA
During meiosis the formation of four nuclei occurs at_____
Prophase 1
Anaphase 2
Metaphase 1
Telophase 2
During prophase, a homologous pair of chromosome consists of____
4 chromosomes and 2 chromatids
2 chromosomes and 2 chromatid
2 chromosomes and 4 chromatid
1 chromosomes and 2 chromatid
After telophase 1 of meiosis, the chromosomal makeup of each daughter cell is____
Diploid and the chromosomes are composed of a single chromatid
Diploid and the chromosomes are composed of the two chromatid
Haploid and the chromosomes are composed of a single chromatid
Haploid and the chromosomes are composed of two chromatid
When comparing prophase 1 of meiosis with prophase of mitosis, which of the following occurs only in meiosis?
The chromosomes condense
Tetrads form
The nuclear envelope disassembles
A spindle forms
When pairs of homologous chromosomes separate during anaphase 1
The maternal chromosomes all move to one daughter cell, and the parental chromosomes cell all move to the other daughter
The sister chromatids remain linked to one another
Most of the recombination has already occurred, with the remainder taking place during prophase 1
Separation of sister chromatid
An important outcome of meiosis 2 is the
Random assortment of homologous chromosomes
Separation of homologous chromosomes
Provision of crossing over during prophase
Separation of chromatids
In animal cells, cytokinesis takes place by
Cytoplasmic contraction
Furrowing process
Membrane fussion
Formation of cell plate
