Before a cell can enter the active phases of mitosis, however, it must go through a period known as interphase, during which it grows and produces the various proteins necessary for division.
What process must take place before meiosis can begin?
Before meiosis actually begins, the DNA that is packaged into chromosomes must be fully copied. Previous to replication, a germ cell contains two copies of each chromosome, a maternal copy, and a paternal copy.
Which of the following must occur before mitosis or meiosis can begin?
Answer Expert Verified. What MUST occur before mitosis and meiosis can occur is B) DNA replication. DNA replication is a process of copying DNA into an identical copy. Before mitosis, the genetic material of the mother cell must duplicate so that each daughter cell have the same amount as the mother cell.
Which process must occur before mitosis can occur quizlet?
Which process MUST occur before mitosis and meiosis can occur? the final phase of cell division, between anaphase and interphase, in which the chromatids or chromosomes move to opposite ends of the cell and two nuclei are formed.
What is process of mitosis?
Mitosis is a process of nuclear division in eukaryotic cells that occurs when a parent cell divides to produce two identical daughter cells. During cell division, mitosis refers specifically to the separation of the duplicated genetic material carried in the nucleus.
What is the difference between mitosis and meiosis?
Cells divide and reproduce in two ways, mitosis and meiosis. Mitosis results in two identical daughter cells, whereas meiosis results in four sex cells. Below we highlight the keys differences and similarities between the two types of cell division.
What is uncoiled stringy DNA called?
What is uncoiled, stringy DNA called? It is called chromatin.
What are the four steps of mitosis in order?
These phases are prophase, prometaphase, metaphase, anaphase, and telophase.
What is mitosis important for?
Mitosis is a process where a single cell divides into two identical daughter cells (cell division). … The major purpose of mitosis is for growth and to replace worn out cells.
