Mitosis
The process that results in new cells with genetic material that is identical to the original cell?
Mitosis.
The process by which the chromosome number is halved?
Meiosis.
The end product of mitosis is the cell having two sets of chromosomes. What is the term used to describe two sets of chromosomes?
Diploid.
What occurs before mitosis and after mitosis?
Before = interphase
After = cytokinesis.
The phase that is considered the opposite of prophase?
Telophase.
The number of phases in mitosis?
Four phases.
The number of cycles that meiosis goes through?
Two.
What are used to arrange and pull the chromosomes?
Spindle fibers.
What happens during interphase?
Make new organelles, cell growth, and DNA is duplicated.
The phase when chromosomes pull apart toward the poles?
Anaphase.
The longest phase in mitosis where chromosomes condense?
The process in meiosis that ensures more genetic variation? Which phase does it occur in?
Crossing over (prophase I).
The part of the chromosome that the spindle fiber attaches to.
Centromere.
What are three things that happen during prophase of mitosis?
1. Spindle fibers form.
2. Nuclear membrane break downs.
3. Chromatin condenses into chromosomes.
the phase where chromosomes reach the poles and decondense/uncoil into chromatain?
Telophase.
This is the location in your body where mitosis takes place?
Body cells or autosomes.
What is the pairing up of homologous chromosomes called? Which phase does it occur in?
Synapsis (prophase I).
The name of reproductive cells
What is the appearance of the daughter cells (when compared to parent cells) during mitosis and meiosis?
Mitosis = genetically identical
Meiosis = genetically different.
the phase where the cytoplasm pinches off
Cytokinesis.
The purpose of mitosis?
Replacement of damaged cells, growth, or asexual reproduction.
What is the difference between anaphase I and anaphase II of meiosis?
Anaphase I = homologous chromosomes separate.
Anaphase II = sister chromatids separate.
What is the difference between metaphase I and metaphase II of meiosis?
Metaphase II = chromosomes individually line up on the center of the cell.
What is the difference between prophase I of meiosis and prophase of mitosis?
Prophase I of meiosis has synapsis and crossing over. Prophase of mitosis does not.
The phase where chromosomes become visible
