Why is the s phase so important?
With twice the amount of chromosomes in the parent cell, each daughter cell can have a normal number of chromosomes after the cell splits in mitosis.
In which phase do chromosomes become visible?
The DNA of a cell condenses to form chromosomes during cell division or mitotis, called the M phase of the cell cycle. Specifically, chromosomes acquire their characteristic X shape in the metaphase stage of mitotis. Each chromosome consists of two sister chromatids joined at the centromere.
What stage are Chromosomes duplicated?
technically the chromosomes copy during interphase right before metaphase I of meiosis I so during Meiosis I the chromosomes are duplicated and not until metaphase II during meiosis II are the sister chromatids separated.
What is a list of the four phase of mitosis in order?
Phase 1- Mitosis begins. Chromosomes condense from long strands into rodlike structures. Phase 2- The nuclear membrane is dissolved. Paired chromatids align at the cell's equator. Phase 3- The paired chromatids separate and move to opposite sides of the cell. Phase 4- A nuclear membrane forms around each set of chromosomes, and the chromosomes decondense. Mitosis is complete.
Chromosomes are duplicated during?
Organelles and chromosomes are copied during S phase and G2 phase of Interphase in Mitosis. More particuarlly, the S phase is where DNA replication occurs and the G2 phase synthesizes proteins and organelles needed in Mitosis.
Why do chromosomes in parent cell duplicate during mitosis?
Chromosomes doubles during the S phase of inter-phase, which occurs before Mitosis. During the process of mitoses cell divides into 2 daughter cells from a single parent hence, before mitoses cells must duplicate so that each new cell has a sufficient set of genetic material.
What occurs during the phase of the cell cycle?
A cell's DNA is copied during this phase. At the end of this phase, each chromosomes consists of two chromadtids attached at he centromere.
What is the phase when there is one set of single stranded chromosomes at each end of the cell?
telophase

During Mitosis the cell is performing its special job?
No, the cell performs its special job during inter phase. During mitosis, the membrane around the cell's nucleus dissolves and the chromatids of each chromosome are separated and pulled to each end of the cell. As the nuclear membrane re-forms around each set of chromosomes, the cytoplasm of the parent cell begins to divide to form two daughter cells.www.answers.com/topic/mitosis

How are sex cells produced and how many chromosomes are present at each stage?
Starts as a germ cell- 46 chromosomes Goes through phase 1 meiosis- 2 daughter cells each 46 chromosomes Goes through phase 2 meiosis- chromosomes are sorted randomly and recombined (crossing over)- gametes (sex cells) 23 chromosomes
Chromosomes are only present in the cell cycle during?
Chromosomes can be seen during cell divison, Reference Before a cell gets ready to divide by mitosis, each chromosome is duplicated (during S phase of the cell cycle
During telophase a nuclear envelope usually surrounds each new set of chromosomes?
Yes it is true that during telophase, a nuclear envelope surrounds each new set of chromosomes. It is also true that cells spend most of their lifetime in inter-phase.
