Mitosis/Meiosis Lecture Quiz Ch 6+7
What is the chromosome number found in a human cell just after meiosis I is completed?
22 autosomes and a sex chromosome
Telophase
After the chromosome seperates, the cell seals off, Final Phase of Mitosis.
prophase
Chromosomes become visable, nuclear envelop dissolves, spindle forms
metaphase
Chromosomes line up in the middle of the cell
In meiosis, how does prophase I differ from prophase II?
During prophase I there is one diploid cell; during prophase II there are two haploid cells.
anaphase
Phase of mitosis in which the chromosomes separate and move to opposite ends of the cell
Which of the following statements are true regarding homologous pairs of chromosomes?
They are the same size Their presence indicates a cell is diploid They line up next to each other during metaphase I of meiosis They are separated in anaphase I of meiosis
How much genetic material is present in a cell during prophase I compared to a cell that has completed meiosis II?
four times as much
During anaphase I ________.
homologous chromosomes randomly separate and migrate to opposite poles
2n=4 cell
is diploid(has homologous chromosomes), has 4 chromosomes, that can have 1 or 2 chromatids each
This diagram of the human life cycle shows that ______
meiosis produces haploid sperm and egg cells
Interphase
period of the cell cycle between cell divisions
Plant cell cytokinesis differs from animal cell cytokinesis because ______
plant cells form a cell plate and animal cells do not
The cells that result from the mitotic cell cycle can be described as _______
two cells, each with the same amount of genetic material and the same genetic information
