DNA a. Structure: Nucleotide Hydrogen Bond -Phosphate -Sugar -Nitrogen Base

b. Replication: DNA copies itself exactly and occurs within the Nucleus. A mistake that occurs in called Mutation (chromosomal Mutation). (C-G) (A-T) DNA polymerase is the enzymes involved Know what each person discovered: Griffith: coined the term transforming principle-(DNA that is transferred from one individual to another in genetic transformation ) Avery: discovered the transforming agent - (DNA) Hershey and Chase: DNA is a molecule of heredity Chargaff: found that certain nucleotides always paired together Franklin: found DNA had a 3D structure Watson and Crick: discovered the double helix .. used Franklin’s work d. Vocabulary: Nitrogen Base: Adenine (A), Guanine (G), Cytosine (C), and Thymine (T).
A binds with T
G binds with C
Phosphate Group: DNA consists of 2 long polymers of simple units called nucleotides, with backbones made up of alternating sugars and phosphates
Sugar:
Deoxyribose: Sugar present in DNA
Ribose: Sugar Present in RNA
Hydrogen Bond: joins the 2 chains and nucleotides together. 3 bonds between C-G and 2 bonds between A-T
Cytosine: C, one of the 4 main bases found in DNA. It bonds with Guanine
Adenine: A, one of the 4 main bases found in DNA. It bonds with Thymine
Thymine: T, one of the 4 main bases found in DNA. It bonds with Adenine
Guanine: G, one of the 4 main bases…
