Daily Trivia • There are more bacteria and microbes in our body than actual cells that make up the body.
I. DNA Replication • DNA is copied – this is called replication • Without DNA replication, a new cell would only have half of it’s information. • All organisms undergo DNA replication
DNA Replication • Because of the complementary pairs - if you have one strand, it is easy to predict the replicated strand. • T-A-G-C-C-G-T • Would be replicated by matching T, with A, G with C • A-T-C-G-G-C-A
F. Steps of DNA Replication • First, an enzyme “unzips” the double helix structure • Then, complementary nucleotides are attached like puzzle pieces.
The unzipping and matching continues until the entire strand is done. • The original DNA now has a complimentary strand. • The result is two DNA molecules which are identical to the original.

G. Enzymes • Helicase – unzips the DNA strand • Primase– starts replication strand • Polymerase – brings complementary bases to join with new strand
H. Genes • Genes are sections of DNA that code for proteins • The order of the nucleotides in the gene is what determines the protein
H. DNA to Protein • Proteins are made up of many amino acids • Remember DNA codes for proteins!
