Stages of Meiosis
Random
100
What is the correct order of stages in mitosis?
Prophase, Metaphase, Anaphase, Telophase Remember: (P-MAT)
100
What are the 3 checkpoints of mitosis that occur in interphase? List in order.
G1 phase, S phase, G2 phase
100
What are the four phases of mitosis? list them in order.
Prophase, Metaphase, Anaphase, and Telophase
100
In which phase do the cells actually separate to form two separate cells?
Cytokinesis
100

What type of cell division produces gametes?

Meiosis

200
Explain what occurs during Interphase.
The cell grow and replicates its DNA and centrioles. Also, it carries out normal cell activities.
200

What phase (of interphase) in the cell cycle does a cell spend the majority of its life?

G1 – Growth phase

200
True or False. Mitosis have two divisions, while meiosis has one.
False, Meiosis has two divisions and Mitosis has one.
200

Are all the cells produced by meiosis identical?

No : because of crossing-over and independent assortment that happens during meiosis.

In which phase does chromatin condense to form chromosomes?
Prophase
300

What occurs in the S phase? 

In the S phase, the chromosomes are replicated and DNA molecules are synthesized. 

300
What type of process does asexual reproduction involve?
Mitosis.
300
In which phase do spindle fibers attach to the chromosomes?
Metaphase 1 and Metaphase 2
300

What are the two identical copies of DNA that make up a chromosome?

Chromatids

400

During mitosis, what attaches to the chromosomes and helps to pull them to opposite ends of the cell?

Spindle Fibers

400

What occurs in the G2 phase? Is it the shortest or longest among the 3 checkpoints/phases of interphase?

During the G2 phase, the cell "double checks" the duplicated chromosomes for errors, making needed repairs. The G2 phase is the shortest checkpoint out of all the checkpoints/phases in Interphase.

400
Is it meiosis or mitosis that produces somatic cells?
Mitosis
400
In which phase do tetrads form?
In prophase of meiosis I.
400

What type of chromosomes are not associated with determining gender in an organism?

Autosomes

500
True or False. In Anaphase, the two sister chromatids separate into individual chromosomes and move apart. In telophase, the chromosomes gather at opposite ends of the cell and the cell splits.
False, it is not in Telophase that the cells split, it is in Cytokinesis. However, everything else stated is correct.
500

What is a cell called that  only has one set of chromosomes?

Haploid cell

500
What types of cells do both process (mitosis and meiosis) result in?
Mitosis- 2 genetically identical diploid daughter cells. Meiosis- 4 genetically different haploid daughter cells.
500
True or False. In Anaphase 1 and Anaphase 2 the homologous chromosomes move toward the opposites ends of the cell.
False, In anaphase 2 the SISTER CHROMATIDS move toward opposites ends of the cell. However, in Anaphase 1 the homologous chromosomes do move toward the opposites ends of the cell.
