set prev As the chromosomes of a parent cell are duplicated and distributed to the two d Answer the three questions for each phase of the cell cycle by dragging the yes and no labels to the appropriate locations in the table. Note: Assume that by the end of the M phase, the parent cell has not yet divided to form two daughter cells. View Available Hint(s) daughter cells during cell division, the structure of the chromosomes changes Reset Help Beginning of M End of M Question early anaphase) telophase) 1. Are sister chromatids present in all or no part of this phase? yes 2. Is the DNA condensed in all or part of no this phase? 3. Does the cell contain twice as much DNA in this phase as it did in the Gi phase?Explanation / Answer
Ans.1. Sister chromatids are fully formed during S (sunthesis) phase of interphase and a full set of chromosome is transferred to each daughter cell. Thus,
Yes, sister chromatids will present at S phase.
Yes, sister chromatids will present at G2 phase.
Yes, sister chromatids will present at beginning of M phase.
Yes, sister chromatids will present at end of M phase.
Ans.2. DNA condenstaion also starts with S phase, however DNA remains least condensed at this state and becomes fully condensed at metaphase. Thus,
Yes, DNA is condensed at S phase.
Yes, DNA is condensed at G2 phase.
Yes, DNA is condensed at beginning of M phase.
Yes, DNA is condensed at end of M phase.
Ans.3. During cell division, DNA replication occurs at S stage of interphase and cell contains twice of DNA of that present in G1 phase. Each daughter cell gets half amount of DNA at the end of mitosis. Thus,
Yes, cell contains twice of DNA as present in G1 phase at S phase.
Yes, cell contains twice of DNA as present in G1 phase at G2 phase.
Yes, cell contains twice of DNA as present in G1 phase at beginning of M phase.
Yes, cell contains twice of DNA as present in G1 phase at end of M phase.
Ans.B
The correct options are:
Vesicles from the Golgi apparatus move along microtubules, coalesce at the plane of cell division, and form a cell plate.
The cell plate consists of the plasma membrane and cell wall that will eventually separates two daughter cells.
