Which process must occur before mitosis can occur?

Which process must occur before mitosis can occur quizlet?

During the cell cycle, specifically interphase, a cell must reach a sufficient size and produce enough ATP in order to replicate its chromosomes.. Most of interphase is spent in G1.

What must happen to DNA before mitosis occurs?

The genetic material, DNA, must undergo replication before a cell enters mitosis. DNA replication results in two identical copies of the DNA.

Which of the following must take place before cell division can occur?

Before division can occur, the genomic information that is stored in chromosomes must be replicated, and the duplicated genome must be separated cleanly between cells.

Which process must occur first before any cell?

Before cells can divide, either through mitosis or meiosis, they must go through interphase.

What happens immediately before mitosis?

Before mitosis starts, all the chromosomes in the nucleus replicate their DNA to make identical copies. The nucleus now contains two sets of replicated chromosomes, twice as many as a normal body cell.

What happens in the stage before mitosis in the cell cycle?

The first stages of the cell cycle involve cell growth, then replication of DNA . The single strand of DNA that makes up each chromosome produces an exact copy of itself. All of the organelles inside the cell are also copied. These processes happen in a stage of the cell cycle called interphase .

What processes occur in interphase cell prior to the onset of mitosis??  G1,S,G2 Cell grows, DNA doubles, and chromatin condenses

What occurs just before the cell enters the G2 stage?

After cell growth during the G1 phase and DNA replication during the S phase, the cell is ready to enter the G2 phase. G2 is called a gap phase because no further cell division-specific progress takes place.

What occurs in each phase of mitosis?

There are four stages of mitosis: prophase, metaphase, anaphase and telophase.1) Prophase: chromatin into chromosomes, the nuclear envelope break down, chromosomes attach to spindle fibres by their centromeres 2) Metaphase: chromosomes line up along the metaphase plate (centre of the cell) 3) Anaphase: sister …
