The original cell is a parent cell, the two new cells are daughter cells

• They are genetically identical 

• The cell cycle involves 

  • Cell growth 

  • Chromosome replication 

  • Chromosomes segregation 

  • Cell division 

G1 and 2 allow for the cell to grow to an appropriate size, they also help with the synthesis of proteins. 

• S phase between G1 and G2 is when DNA replicates and chromosome duplication occurs. 

Chromosomes is a continuous strand of DNA before replication 

Chromatids are after DNA replication 

• They are connected by a centromere 

• It is only when cell division that takes place is when they equal two daughter chromosomes

Haploid cells have one set of chromosomes

• Like gametes (eggs and sperm) 

  • N = 23 

Diploid cells are in most organisms and 2n = 46 

Mitosis is the process when sister chromatids split and make two daughter cells. 

Mitotic spindles separate into two new daughter cells. 

The centrosome consists of two centrioles 

MITOSIS STAGES 

Prophase: 

1. Chromosomes condense in the nucleus 

Prometaphase: 

1. The nuclear envelope breaks down 

Metaphase 

1. Is the lining along the equator 

Anaphase 

1. Is the separation of chromatids to make two daughter chromosomes. 

Telophase 

1. In the last stage, two sets arrive at opposite poles and condense

   1. Cleavage furrow is not showing yet 

Cytokinesis 

1. Is the division of the cytoplasm
