DNA synthesis (or replication) occurs during this phase. At the beginning of the phase, each chromosome is single. At the end, after DNA replication, each chromosome consists of two sister chromatids.
What is S phase?
100
A human bone marrow cell, in prophase of mitosis, contains 46 chromosomes. It will also contain 92 of these.
What are chromatids?
100
During metaphase these are located at opposite poles of the cell.
What are centrosomes?
100
During this stage in Mitosis two daughter nuclei and nuclear envelopes form, along with the uncoiling of chromosomes, this stage completes the Mitosis, the division of one nucleus into two genetically identical nuclei.
What is Telophase?
100
An organic process in the cell cycle consisting of the division of the cytoplasm of a cell, following karyokinesis, (division of the nucleus) bringing about its separation into two daughter cells.
What is cytokinesis?
200
Cell division occurs during this short phase, which generally involves two discrete processes: the contents of the nucleus (mainly the duplicated chromosomes) are evenly distributed to two daughter nuclei, and the cytoplasm divides in two.
What is the Mitotic phase.
200
In this phase of mitosis, the chromatin condenses into discrete chromosomes. The nuclear envelope breaks down and spindles form at opposite poles of the cell
What is prophase?
200
A structure located at a plane equidistant between the two spindle's poles of a cell in metaphase on which the centromeres of all the duplicated chromosomes are located.
What is the metaphase plate?
200
During this stage of Mitosis centromeres divide, sister chromatids become full-fledged chromosomes, and begin moving towards opposite ends of the cell as their kinetochore microtubules shorten.
What is anaphase?
200
The terms "Migration, Shortening and Thickening, Cytokinesis, Centrioles Forming," can be directly associated with these different stages of Mitosis.
What is Anaphase, Prophase, Telophase, Prophase?
300
During this stage in the cell cycle, it difficult to observe individual chromosomes with a light microscope because they have uncoiled to form long, thin strands.
What is interphase?
300
During this phase spindle fibers attach to kinetochores, (a specialized structure at the centromere) and the chromosomes break the nuclear envelope, and attach to microtubules.
What is prometaphase?
300
DAILY DOUBLE!!
1.) The ________ of each pair of chromatids becomes attached to two spindle fibers-one from each side of the cell
2.) This action occurs when a cell phone goes off in class.
1.) What is the centromere?
2.) What is Professor Butler dancing?
300
Somatic cells that do not replicate, or otherwise divide or reproduce.
What are nerve cells or neurons?
300
Dark round bodies where ribosomes are synthesized, these are broken down during prophase.
What are Nucleoli?
400
This is when division of the nucleus occurs. The chromosomes that have been replicated are distributed to two daughter nuclei.
What is Mitosis
400
During Prophase these two small structures move to opposite ends of the cell; it is between these structures that the spindle fibers stretch across the cell.
What are centrioles?
400
Two identical strands joined by a common centromere as a result of a chromosome that duplicated during the S phase of the cell cycle.
What are sister chromatids?
400
When these proteins are cleaved, sister chromatids parts and becomes a chromosome.
What are cohesin proteins?
400
During cell division, vesicles containing cell wall material go to the middle of the cell and start growing outwards forming a new cell wall separating the new daughter cells
What is the cell plate?
500
This depends on what the parent cell looks like since the daughter cells are identical. The daughter cells will be haploid if the parent cell is haploid, or diploid if the parent cell is diploid.
What contributes to composition of the daughter cells?
500
Signals within a cell that tell whether the cell is ready for the next stage in the cell cycle, this occurs during Interphase sub-phases: G1, G2, and Mitosis.
What is cell cycle checkpoints?
500
During cell division, vesicles containing cell wall material go to the middle of the cell and start growing outwards forming a new cell wall separating the new daughter cells.
What is the cell plate?
500
A star-shaped structure formed in the cytoplasm of a cell having fibers like rays that surround the centrosome during mitosis.
What is an Aster or Asters?
500
Caving in of membrane as microfilaments tighten to pinch apart the cell into two daughter cells.
