- - - - Base
  - - - Adenine pairs with Thymine
        
        Cytosine pairs with Guanine
- - - - primase = add primers and start the replication
        
        polymerase = remove the primers and add DNA nucleotides
        
        Ligase = Joins the nucleotides together
      - Detailed process:
        
        Helicase needs to unzip/ unwind the DNA strand
        
        Primase needs to add primers to each strand and start the replication
        
        Polymerase removes the primers, extending DNA strands and add nucleotides (base pairings)
        
        Ligase joins the fragments together to complete the lagging strand.
- - - - Prophase (start
        
        Metaphase (middle)
        
        Anaphase (away)
        
        Telophase (two)
        
        Cell membrane is separated into two daughter cells, followed by cytokinesis
        
        Sister chromatids are pulled away from the middle of the cell
        
        Chromosomes line up in the middle of the cell
        
        DNA has condensed and mitosis begins
      - Before mitosis starts, DNA is replicated
- - - - Prophase 1:
        
        Metaphase 1
        
        Anaphase 1
        
        Telophase 1
        
        Prophase 2
        
        Metaphase 2

        Second round of meiosis starts
        
        Parent cell pinched in half. Two daughter cells formed.
        
        Homologous chromosomes point away and separate from each other
        
        Homologous chromosomes line up in pairs in cell's middle
        
        Meiosis starts
      - DNA replicates

        Genetic thread-like material of an organism made of protein
        
        Physical unit of heredity which is made of DNA
        
        A trait that is hidden
      - A trait that is expressed
- - - - Incomplete dominance:
        
        Co-Dominance:
        
        Speckled chicken have both black (BB) and white (WW) traits shown on them, resulting in genotypes of BW showing both traits.
        
        Snapdragons flower can be red (RR - homozygous), white (rr - homozygous) or pink (Rr - heterozygous). The pink trait is somewhere in between red and white trait.)
    - - Type B:
        
        Type AB (co-dominance)
        
        Type O (recessive)
