What is the part of the cell cycle process by which chromosomes in a cell nucleus are separated into two identical sets of chromosomes each in its own nucleus?
In the context of the cell cycle, mitosis is the part of the division process in which the DNA of the cell’s nucleus is split into two equal sets of chromosomes.
Which nutrient is responsible for cell growth?
Amino acids, the building blocks of proteins, are also essential nutrients for cell growth. Amino acids can also be used for the synthesis of nucleic acid, glucose, and ATP.
What occurs when more cells are needed?
Mitosis occurs whenever more cells are needed. It happens throughout the entire lifespan of a living organism (human, animal or plant) but most rapidly during periods of growth.
What is the part of the cell cycle process by which chromosomes?
The mitotic phase is a multistep process during which the duplicated chromosomes are aligned, separated, and move into two new, identical daughter cells. The first portion of the mitotic phase is called karyokinesis, or nuclear division.
How does cell growth happen?
Cellular growth is ensured by alternation of DNA duplication and cell division cycles. This alternation is coordinated by the interplay between enzymatic activities, called kinases, and transcription factors, to keep the cell cycle timing.
In which phase of the cell cycle do cells spend most of their time?
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.
Which of the following is a function of mitosis in human?
Mitosis is a process where a single cell divides into two identical daughter cells (cell division). During mitosis one cell? divides once to form two identical cells. The major purpose of mitosis is for growth and to replace worn out cells.
