Chromosomes | Interphase | Stages of Mitosis 1 | Stages of Mitosis 2 | Checkpoints |
---|---|---|---|---|
What are kinetochores?
This protein holds sister chromatids together.
|
What is G1?
The first phase in which a cell grows is known as this.
|
What is the cell cycle?
____ allows for the reproduction, growth, and tissue repair of cells.
|
What is telophase?
During this phase, two daughter nuclei form, nucleoli reappears, and chromosomes become less condensed.
|
What is apoptosis?
During the G2 checkpoint, if damage to a cell cannot be repaired, the cell will undergo ____.
|
What is chromatin?
Chromosomes are an organized and condensed form of this.
|
What is the S phase?
In ____ phase, DNA replicates.
|
What is prophase?
In this phase, chromatin condensed, nucleoli disappear, mitotic spindles begin to form, and centrosomes move apart.
|
What is cytokinesis?
____ is the name of the stage in which a cell divides into two daughter cells.
|
What is the M (spindle) checkpoint?
This checks for microtubule attachment to chromosomes at the kinetochore during metaphase.
|
What are sister chromatids?
When two copies of the same chromosome join together, they become known as this.
|
What is G2?
In this phase, a cell grows more, and prepares for mitosis
|
What is prometaphase?
In this phase, the nuclear envelope fragments and microtubules enter the nuclear area and attach to kinetochores.
|
What is prophase, prometaphase, metaphase, anaphase, and then telophase and cytokinesis?
Mitosis goes in this order.
|
What is the G1 checkpoint?
This is the most important checkpoint, and it checks for cell size, growth factors, and DNA damage.
|
What are the protein histones?
DNA wraps around ___ to form nucleosomes, which then form chromatin.
|
What is the S phase?
In this phase, chromosome duplication occurs.
|
What is metaphase?
In this phase, centrosomes are at opposite poles, chromosomes line up in the center on the metaphase plate, and microtubules fully attach to each kinetochore.
|
What is a plant cell?
In this type of cell, a cell plate forms during cytokinesis.
|
What is DNA replecation?
During the G2 checkpoint, the cell checks for the completion of ____.
|
What is 46?
Humans have ____ amount of chromosomes.
|
What is interphase?
____ is the longest portion of the cell cycle.
|
What is anaphase?
During this phase, sister chromatids separate and move to opposite ends caused by the shortening on the microtubules. The cell also elongates.
|
What is a somatic cell?
This type of cell is diploid, and divides by mitosis.
|
What is a muscle/nerve cell?
This type of cell stops at the G1 checkpoint, and stays in G0 for the rest of it’s life.
