The process by which a cell divides into two new daughter cells.
What is cell division?
100
This is the phase that prepares the cell for mitosis.
What is interphase?
100
This happens to the chromosome number during the early phases of meiosis.
What is, "It Doubles"?
100
Spindle fibers attach to the chromosomes.
What is Metaphase I?
100
Organisms that reproduce asexually may do so through cell division. This process is called what?
What is mitosis?
200
A chromosome consists of two identical sister ______?
What are chromatids?
200
The first phase of mitosis. The chromosomes become visible.
What is prophase?
200
In this phase of meiosis, the chromosome number reduced.
What is Anaphase I?
200
Each chromosome pairs with its corresponding homologous chromosome to form a tetrad.
What is Prophase I?
200
In eukaryotes, what are the single celled organisms called?
What are protists?
300
During this phase, DNA is replicated.
What is S-Phase?
300
The chromosomes begin to disperse into a tangle of dense material. A nuclear envelope forms around the chromosomes.
What is Telophase?
300
A diploid human cell contains _____ pairs of homologous chromosomes, or a total of ______ chromosomes.
What is 23 and 46?
300
Chromosomes line up.
What is Metaphase II?
300
Chromatids attached to each other at this part.
What is the centromere?
400
This means that each of the chromosomes that came from the male parent has a corresponding chromosome from the female parent.
What is homologous?
400
The chromosomes line up across the center of the ell.
What is Metaphase?
400
As a cell enters meiosis 2, the cell contains ______ chromosomes, or ______ chromatids.
What is 46 & 92?
400
As homologous chromosomes pair up and form tetrads in meiosis I, they exchange portions of their chromatids in a process called ________?
What is crossing-over or recombination?
400
A normal cell is ___________ .
What diploid?
500
Where PMAT happens.
What is the nucleus?
500
Centromeres split. Sister chromatids separate and become individual chromosomes.
What is Anaphase?
500
A reproductive cell, containing 46 chromosomes will yield cells with _____ chromosomes each after meiosis.
What is 23?
500
The fibers pull the homologous paired chromosomes towards opposite ends of the cell.
