Chromosomes Interphase Stages of Mitosis 1 Stages of Mitosis 2 Checkpoints
100
What are kinetochores?
This protein holds sister chromatids together.
100
What is G1?
The first phase in which a cell grows is known as this.
100
What is the cell cycle?
____ allows for the reproduction, growth, and tissue repair of cells.
100
What is telophase?
During this phase, two daughter nuclei form, nucleoli reappears, and chromosomes become less condensed.
100
What is apoptosis?
During the G2 checkpoint, if damage to a cell cannot be repaired, the cell will undergo ____.
200
What is chromatin?
Chromosomes are an organized and condensed form of this.
200
What is the S phase?
In ____ phase, DNA replicates.
200
What is prophase?
In this phase, chromatin condensed, nucleoli disappear, mitotic spindles begin to form, and centrosomes move apart.
200
What is cytokinesis?
____ is the name of the stage in which a cell divides into two daughter cells.
200
What is the M (spindle) checkpoint?
This checks for microtubule attachment to chromosomes at the kinetochore during metaphase.
300
What are sister chromatids?
When two copies of the same chromosome join together, they become known as this.
300
What is G2?
In this phase, a cell grows more, and prepares for mitosis
300
What is prometaphase?
In this phase, the nuclear envelope fragments and microtubules enter the nuclear area and attach to kinetochores.
300
What is prophase, prometaphase, metaphase, anaphase, and then telophase and cytokinesis?
Mitosis goes in this order.
300
What is the G1 checkpoint?
This is the most important checkpoint, and it checks for cell size, growth factors, and DNA damage.
400
What are the protein histones?
DNA wraps around ___ to form nucleosomes, which then form chromatin.
400
What is the S phase?
In this phase, chromosome duplication occurs.
400
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.
400
What is a plant cell?
In this type of cell, a cell plate forms during cytokinesis.
400
What is DNA replecation?
During the G2 checkpoint, the cell checks for the completion of ____.
500
What is 46?
Humans have ____ amount of chromosomes.
500
What is interphase?
____ is the longest portion of the cell cycle.
500
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.
500
What is a somatic cell?
This type of cell is diploid, and divides by mitosis.
500
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.
