Does the cell spends most of the cell cycle in mitosis?

Does the cell spends most of the cell cycle in mitosis?

​Cell Cycle A cell spends most of its time in what is called interphase, and during this time it grows, replicates its chromosomes, and prepares for cell division. The cell then leaves interphase, undergoes mitosis, and completes its division.

Where does a cell spend 90% of its life?


How many hours does a cell spend in mitosis?

2 hours

How many cell cycles are there in mitosis?

four stages

Why an increase in the amount of DNA is important in the cell cycle?

The S-phase portion of interphase is when the DNA content of a cell increases. During the S phase, the cell replicates its genetic material so that each chromosome will contain two molecules of DNA. Thus, upon completion of the S phase, the cell has the same number of chromosomes, but its DNA content has doubled.

What does DNA polymerase do in DNA replication?

DNA polymerase is responsible for the process of DNA replication, during which a double-stranded DNA molecule is copied into two identical DNA molecules. Scientists have taken advantage of the power of DNA polymerase molecules to copy DNA molecules in test tubes via polymerase chain reaction, also known as PCR.

How does DNA polymerase bind to DNA?

DNA polymerase “reads” the existing DNA strands to create two new strands that match the existing ones. DNA polymerase’s rapid catalysis is due to its processive nature . In the case of DNA polymerase, the degree of processivity refers to the average number of nucleotides added each time the enzyme binds a template.

What is the difference between the functions of DNA polymerase III and DNA polymerase I?

DNA polymerase 3 is essential for the replication of the leading and the lagging strands whereas DNA polymerase 1 is essential for removing of the RNA primers from the fragments and replacing it with the required nucleotides. These enzymes cannot replace each other as both have different functions to be performed.
