Mitosis + Meiosis Flashcards
What is the best explanation for why chromosomes line up in the center of the cell before starting to split apart during mitosis.
To make sure each daughter cell gets the correct amount of DNA.
Centromeres divide in which phase of mitosis
Anaphase
The nuclear envelope breaks down in ______ during mitosis
Prophase
What happens during meiosis 1
Homologous chromosomes separate into two different cells
What happens before meiosis occurs (pre-meiosis)
DNA replicates
Which of these events occur during Meiosis 2:
A. DNA replicates
B. Homologous chromosomes separate into two cells
C. Replicated chromosomes are separated into sister chromatids and segregated into daughter cells
C.
What is the difference between the parent cell (pre-meiosis) and one of the four daughter cells
The daughter cells have half as much genetic information as the parent cell; one copy of each chromosome instead of a pair of each chromosome
During which phase of meiosis, meiosis 1 or 2, can homologous chromosomes exchange some genetic information
Meiosis 1
At what stage in meiosis, meiosis 1 or 2, would you consider the cells undergoing meiosis haploid cells
After meiosis 1
What is the correct order of phases during mitosis
Prophase, metaphase, anaphase, telophase
What stage of mitosis does the nuclear membrane break down
Prophase
The phase in cell division, in which the parent cell splits into two new daughter cells, is called…
Cytokinesis
In mitosis, during prophase, the ______ move towards the poles of the cell, and a spindle begins to form between them
Centrioles
In which phase of mitosis does the membrane around the nucleus disappear
Prophase
What is the phase of mitosis in which spindle fibers attach to the centromeres of sister chromatids
Metaphase
