What happens during during DNA replication?

Replication occurs in three major steps: the opening of the double helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment. During separation, the two strands of the DNA double helix uncoil at a specific location called the origin.

What is the purpose of DNA replication in mitosis?

The purpose of DNA replication is to produce two identical copies of a DNA molecule. This is essential for cell division during growth or repair of damaged tissues.

What happens during mitosis?

Mitosis is the process of nuclear division, which occurs just prior to cell division, or cytokinesis. During this multistep process, cell chromosomes condense and the spindle assembles. … Each set of chromosomes is then surrounded by a nuclear membrane, and the parent cell splits into two complete daughter cells.

What happens during 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

What two processes happen during mitosis?

This process involves replication of the cell’s chromosomes, segregation of the copied DNA, and splitting of the parent cell’s cytoplasm.

How is the replication of DNA is important in mitosis and meiosis?

If a single cell dies it can be replaced through mitosis. The two daughter cells are identical to the original cell whose DNA was copied. … Life is dependent on the information stored on the DNA. Without replication of the DNA the information would not be passed on and life would cease to exist.
