How many chromosomes are in a daughter cell after mitosis?
How many chromosomes are in a daughter cell after mitosis?
30 chromosomes
How many chromosomes will each daughter cell have if a parent cell has 16 chromosomes?
Assuming that the organism is diploid, if a parent cell has 16 chromosomes and undergoes meiosis, the resulting cells will have exactly 8 chromosomes…
How many chromosomes are in each daughter cell at the end of meiosis?
By the end of meiosis, the resulting reproductive cells, or gametes, each have 23 genetically unique chromosomes. The overall process of meiosis produces four daughter cells from one single parent cell. Each daughter cell is haploid, because it has half the number of chromosomes as the original parent cell.
How many chromosomes are in parent cells in mitosis?
46 chromosomes
How many chromosomes did each of your daughter cells contain?
46
What happens to chromosomes during mitosis?
Mitosis is the process of nuclear division, which occurs just prior to cell division, or cytokinesis. During this multistep process, cell chromosomes condense and the spindle assembles. Each set of chromosomes is then surrounded by a nuclear membrane, and the parent cell splits into two complete daughter cells.
How many chromosomes are there before mitosis?
How many times do chromosomes separate during the process of mitosis?
Finally, once anaphase is complete, the cell enters the last stage of the division process — telophase. During telophase, the newly separated chromosomes reach the mitotic spindle and a nuclear membrane forms around each set of chromosomes, thus creating two separate nuclei inside the same cell.
Why do chromosomes condense during mitosis?
Why do chromosomes condense during mitosis? Chromosomes condense in order to make chromosomes which consists of sister chromatids. What do CDK’s do during the cell cycle? Active enzyme to start cell activity.
Does chromatin condense during mitosis?
Chromatin condensation begins during prophase (2) and chromosomes become visible. Chromosomes remain condensed throughout the various stages of mitosis (2-5). However, when eukaryotic cells are not dividing — a stage called interphase — the chromatin within their chromosomes is less tightly packed.
Why do chromosomes coil during mitosis?
In eukaryotic cells, the nucleus divides before the cell itself divides. The process in which the nucleus divides is called mitosis. It is this coiled structure that ensures proper segregation of the chromosomes during cell division. During other phases of the cell cycle, DNA is not coiled into chromosomes.
Which of the phases of mitosis has the shortest duration?
In anaphase, the shortest stage of mitosis, the sister chromatids break apart, and the chromosomes begin moving to opposite ends of the cell. By the end of anaphase, the 2 halves of the cell have an equivalent collection of chromosomes.
How long does it take to grow the first 20 cells?
The rate of cell growth is increasing,its takes about 20 hours to grow 10 ells ,but it only takes 2-3 hr to grow the last 20 cellsExtend your thinking: In living organisms, the cell cycle is closely regulated.
Which phases were the most difficult to distinguish between?
# Since prophase and prometaphase are difficult to distinguish, classify these cells as prophase.
What happens when less mature cells divide too rapidly?
DNA damage can turn off genes involved in cell-signaling pathways. Turning off. cause less-mature cells to divide too rapidly, often leading to the development of jyfye9775 is waiting for your help.
Why is important that cells have a control system to regulate the timing of cell division?
Why do you think it is important that cells have a “control system” to regulate the timing of cell division? It is important that cells have a “control system” because without it cells would either divide too fast or cause tumors to grow (cancer), or divide too slow and not be able to perform their cellular functions.
Which phase of mitosis is shown in the photomicrograph quizlet?
Meta-phase
Which phase of the cell cycle is most affected by cytarabine?
Its mode of action is due to its rapid conversion into cytosine arabinoside triphosphate, which damages DNA when the cell cycle holds in the S phase (synthesis of DNA). Rapidly dividing cells, which require DNA replication for mitosis, are therefore most affected.
What cell is most affected by cytarabine?
This drugs affect the cell cycle at the synthesis or S phase. The cytarabine causes the rapid conversion of cytosine into cytosine arabinoside triphosphate that plays an important role in the S phase of cell cycle. Thus, the correct answer is S phase.
Which part of the cell is most affected by cytarabine?
The “normal” cells most commonly affected by chemotherapy are the blood cells, the cells in the mouth, stomach and bowel, and the hair follicles; resulting in low blood counts, mouth sores, nausea, diarrhea, and/or hair loss. Different drugs may affect different parts of the body.
What part of the cell cycle does cytarabine affect?
Cytotoxicity is highly specific for the S phase of the cell cycle. Cytarabine acts through direct DNA damage and incorporation into DNA.
