Title Box 1: What is DNA?

DNA = Deoxyribonucleic Acid

Code for your genes (traits)

DNA = nucleic acids = nucleotide

Title Box 2: What is a nucleotide?

Nucleotide = monomer that makes ups nucleic acids (DNA/RNA)

Made up of 3 parts Phosphate group Sugar Nitrogen Base

Base-Pair Rule

Double Helix

The sides of the DNA ladder are phosphate & sugar

Middle are the nitrogen bases:

Title Box 3: What is the structure of DNA?

Title Box 4: What happens during replication? Replication –

process by which DNA is duplicated before a cell divides.

Semi-conservative: when DNA is copied its made up of one new and one old strand

Title Box 5: What are the base-pair rules of DNA?

There are 4 nitrogen bases: Adenine (A) <==> Thymine (T)Guanine (G) <==> Cytosine (C)

Practice: write the complementary DNA strand

A   T   A      T   C   A      T   G   C      T A T    A   G   T      A  

C   G
