Three hundred trout are needed to support one man for a year.  The trout, in turn, must consume 90,000 frogs, that must consume 27 million grasshoppers that live off of 1,000 tons of grass.  -- G. Tyler Miller, Jr., American Chemist (1971)

Prokaryotic Cell Reproduction
Binary fission
Produces identical offspring
Steps
1. DNA is copied
2. Cell is divided
From:

16. Terminology Somatic Cell Gamete (Germ cell or sex cell) Gene
7/21/2019
Terminology
Somatic Cell
Any cell in the body that isn’t a gamete
Gamete (Germ cell or sex cell)
Sperm or ovum
Gene
Segment of DNA used as instructions to code for a trait
1000s per chromosome

17. Chromosomes Made from DNA Formed from chromatin
7/21/2019
Chromosomes
Made from DNA
Genetic material that directs activities and determines characteristics
Formed from chromatin
Right before mitosis
Chromatin coils up into rods

18. Eukaryotic Cell Reproduction (Mitosis)
7/21/2019
Eukaryotic Cell Reproduction (Mitosis)
Each chromosome (at this point) is made up of 2 identical chromatids
Joined strands of identical duplicated genetic material
Joined at centromere
Chromatids separate and each cell has identical information
Formed in S phase of cell cycle
Chromosome Number in Various Organisms
& Chromosome Structure

Sets of chromosomes
Each human somatic cell has 23 pairs of chromosomes (46 total)
Homologous chromosomes
Each pair is called homologous
Similar in size, shape and genetic content
Not identical!
One from each parent
