Define the following: chromosome, centromere, centrosome, kinetochore, mitosis, cytokinesis, syncytium.
A cell in G1 of interphase has 8 chromatins. How many chromosomes and how many DNA molecules will be found per cell as this cell progresses through the following stages:
a) metaphase
b) anaphase
c) after cytokinesis in mitosis
d) metaphase I
e) anaphase I
f) metaphase II
g) anaphase II
h) after cytokinesis of meiosis II
Indicate the stage of mitosis (interphase = I, prophase = P, metaphase = M, anaphase = A, telophase = T) during which each of the following events occur.
chromatid doublets separate to individual chromosomescentriole replicatesreplicated chromosomes (chromatid doublets) are arranged in single file next to one another at the cell's equatornuclear membrane is disappearingspindle fibers form and become visiblecell plate (plant) or cleavage furrow (animal) forms and is visiblechromosomes are at opposite poles of the cell; cytokinesis is almost completedchromosomes (chromatids) first become visible as long thin strandsDNA (chromosome) replication occurs

- create a Venn diagram of the following types of cell division processes: mitosis, meiosis, and binary fission.arrow_forwardCompare and contrast mitosis and cytokinesis by sorting the choices below. Some choices may apply to both.

- Which of the following best describes the difference between interphase and mitosis? a) During interphase, DNA has a loose structure that condenses during mitosis. b) During interphase, histones help compact DNA into chromosomes. And once mitosis starts, histones are destroyed. c) During interphase, DNA is tightly packed into chromosomes that uncoil once mitosis starts. d) During interphase, DNA is packed as chromosomes. And during mitosis, DNA is called chromatin. Please I need a surely answer and a quicker responsearrow_forwardThe cell division process that cells in culture undergo includes the following stages in temporal order: O a) Telophase, anaphase, prophase, metaphase O b) Anaphase, metaphase, prophase, telophase O c) Metaphase, prophase, telophase, anaphase O d) Prophase, metaphase, anaphase, telophasearrow_forwardDescribe the movements of chromosomes and the status of microtubule spindle during interphase, prophase, metaphase, anaphase and telophase?arrow_forward
- Explain what happens at each phase of cell cycle: -DNA replication (when, where, how? Use terms such as DNA polymerase, complimentary base pairs) -Interphase (G1, S, G2) -Mitosis (overall goal of prophase, metaphase, anaphase, telophase, cytokinesis)arrow_forwardDescribe the cell cycle using the following words: Interphase G1 G2 S phase M phase (mitosis) Prophase Metaphase Anaphase Telophase Cytokinesis Apoptosis Check Points feedbackarrow_forwardEven though cytokinesis is included with Mitosis, we generally consider it to be its own phase. Why? by the time cytokinesis occurs, the cell has already split by the time cytokinesis occurs, the cytoplasm has already split by the time cytokinesis occurs, the nucleus has already split by the time cytokinesis occurs, the cell has copied all of its chromosomesarrow_forward
- Describe the following stages of the cell cycle: interphase and mitosisarrow_forwardDraw diagrams for each phase of Mitosis in the correct order. Including Mitosis as part of the cell cycle is beneficial but not required. Identify the most important relevant details about each phase. There are at least 2 details or terms associated with each phase. Please use the proper names for parts such as centromeres, spindle fibres, etc.arrow_forwardSister chromatids separate and the new chromosomes begin to move toward the poles. Name: The chromosomes reach the poles, the nuclear envelope reforms, chromatin decondenses, and now the cell is ready for cytokinesis. Name: 101arrow_forward
