Cell Division Leads to Growth
Most Cells Divide Through Mitosis
Mitosis: a type of cell division that results in two cells, each having the same number and kind of chromosomes as the parent nucleus, typical of ordinary tissue growth.
Book Vocabulary Words:
Gene: A sequence of DNA that contains the information to make at least one protein
Gene Expression: The process of using DNA instructions to make proteins.
Genotype: Genetic makeup of an organism
Phenotype: the physical qualities of an organism including observable or not observable traits
Alleles: alternative versions of the same gene that have different nucleotide sequences.
Cell Division: the process by which a cell reproduces itself; it is normal and essential for growth and healing of tissues
Sister Chromatid: one or more identical DNA molecules that make up a duplicated chromosome following DNA replication
Centromere: the specialized region of a chromosome where the sister chromatids are joined
Cytokiness: the physical division of a cell into two daughter cells

Meiosis: A specialized type of cell division that generates unique haploid gametes. Generates sex cells.
Gamete: specialized reproductive cells that carry one copy of each chromosome, sperm are male gametes, egg are female gametes
Haploid: having only one copy of every chromosome
