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
