Question

!!! Three Medal Question !!!

- Identify the phases of the eukaryotic cell cycle.

- What happens during interphase?

- Describe binary fission

Answer 1

Binary fission single reproduction in which a single cell divides into 2 by simple means. Usually it's obeserved in bacteria. @tanya123

Answer 2

and where are phases to identify?

Answer 3

yup yup, @khadeeja

Answer 4

-Interphase, which consists of G1, Synthesis (S), and G2The Mitotic phase, which consists of mitosis.Cells that do not divide go into the G0 phase, or "cell cycle arrest."

-Interphase is the phase of the cell cycle in which the cell spends the majority of its time and performs the majority of its purposes.
During interphase the cell obtains nutrients, and it is considered as the living phase of the cell.
Most eukaryotic cells spend most of their time in interphase. Interphase is a resting phase.
This is the longest part of the cell cycle.
There are 3 stages of interphase:
G1, in which the cell grows and functions normally.
During this time, a lot of protein synthesis occurs and the cell "grows" - more organelles are produced and increasing the volume of the cytoplasm.
If the cell is not to divide again, it will remain in this phase.
synthesis (S), in which the cell duplicates its DNA (via semi-conservative replication).
G2, in which the cell ensures that its chromosomes and organelles are ready for mitosis.
The proteins necessary for cell division are also made (e.g. the proteins needed for the microtubules to form the spindle fibres).
Duration is variable and depends on the function of the cell.
Some human cells divide every 24 hours; in this case interphase takes about 22 hours and
Interphase is the period during which the cell's organelles carry out their functions, causing the nucleolus to increase in size.
The time that mitosis takes therefore depends on the variety and size of the cell.
In interphase, the cell gets itself ready for Mitosis or Meiosis.
Somatic cells go through mitosis and gametes go through meiosis.
Interphase is not the first stage of mitosis but prophase is, due to contrary belief.

-Binary fission is a kind of sexual reproduction. This kind of a sexual reproduction is best represented by protozoa. It is a precursor to the mitosis process in higher organisms.

Answer 9

did it help @tanya123

Answer 10

----> The eukaryotic cell cycle is somewhat more complex than the prokaryotic
growth cycle. In large part this is because eukaryotic cells contain multiple chromosomes
within a membrane-bound nucleus, rather than a single circular chromosome within the
cytoplasm. Because of this, the processes of DNA replication and partitioning are
somewhat more complex. During cell division, eukaryotic chromosomes follow a very prescribed series of events, almost like a choreographed dance, as they replicate and move from one parent cell into two daughter cells.
----> During Interphase the cell grows to its mature size, makes a copy of its DNA, and prepares to divide into two cells.
----> prokaryotes multiply by simple cell division. The DNA of the chromosome is replicated and then the cell divides with usually half of the cytoplasm going to each daughter cell. One of the replicated chromosomes goes to each daugther as well.

Binary fission is a kind of sexual reproduction. This kind of a sexual reproduction is best represented by protozoa. It is a precursor to the mitosis process in higher organisms.
