Mitosis in Real Cells
What is the chromosome number found in a human cell just after meiosis I is completed?
22 autosomes and a sex chromosome
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
Interphase
period of the cell cycle between cell divisions
telophase
the chromatids or chromosomes move to opposite ends of the cell and two nuclei are formed.
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
