- - - - Transcription is when a DNA is a gene is copied to produce an RNA transcript called messenger RNA (mRNA)
        
        RNA polymerase, an enzyme, uses bases from a nucleus to form mRNA.
        
        Rna only has a single strand of bases called uracil
        
        DNA strands have thymine
    - - Translation occurs after transcription
        
        DNA is transferred to ribosomes, protein makers
        
        Messages carried by mRNA is read by transfer RNA (tRNA)
        
        tRNA transfers the message to the ribosome which binds to the codon.
        
        Initiation
        
        Occurs at the ribosome
        
        The ribosome find mRNA
        
        tRNA carries the start codon base pairs
        
        Anticodon
        
        Elongation
        
        The ribosomes shifts
        Other tRNA brings amino acids together joining the polypeptide chain (peptide bond)
        
        termination
        
        Ends with a stop codon
        
        The release factors causes the ribosome to detach
        
        mRNA can then be recycled
- - - - ONE LESS OXYGEN MOLECULE
    - - Bases
      - Adenine and Guanine
      - Purines
      - 2 ring
      - Thymine and Cytosine
      - 1 ring
      - A always pairs with T
      - C always pairs with G
      - Can not leave the the nucleus
      - Hydrogen Bonds
      - A and T have two hydrogen bonds
      - G and C have three hydrogen bonds
      - The double strands run antiparallel.
