9.1 What Are the Functions of Cell Division?
Genetic material
Structure of DNA
DNA is a polymer composed of many nuclteotides.
DNA is packaged into chromosomes
The units of inheritance in DNA are genes, these are segments of chromosomal DNA that have a wide range of nucleotide lengths.
Growth, development, and repair
Categories of cells
Permanently differentiated cells:
Differentiated cells capable of dividing
Cells with the potential of self-renewal and potency
Human growth from a fertilized egg is only possible because of mitotic cell division
This process also helps repair injuries and replacing cells.
The repeating pattern of cell division is called the cell cycle.
Sexual and asexual reproduction
Sexual
Reproduction by fusion of gametes
Asexual
Offspring of a single parent, no sperm fertilizes eggs.
Daughter Cells
One of two cells formed by a cell division
Cell Division
Splitting of one cell into two; the process of cellular reproduction
