DNA STRUCTURE

4 BASESWhat are my four bases?

Adenine, Guanine, Cytosine, and Thymine

WHAT IS MY SAYING TO REMEMBER BASE PAIRS?

Apples in the Tree, Cars in the Garage

BASE PAIRSWhat are my base pairs?

A-TC-G

NUCLEOTIDES

What three parts make up a nucleotide?

Sugar, Phosphate, Base

Purine =A&G Pyrimidine=C,T&U

ANTI PARALLEL STRUCTUREDependent on which carbon on the sugar molecule the phosphate is attached to.

On one side of the DNA, ALL nucleotides must be flipped in order for the base pairs to match up in the middle of the DNA

RNA

FOUR BASES

What are my four bases for RNA?

AdenineGuanineUracil Cytosine

PYRIMIDINE AND PURINE BASES OF RNA

Pyrimidines Uracil Cytosine

PurinesAdenineguanine

RNA NUCLEOTIDE-Uses Ribose as the sugar-Uses uracil, not thymine as a base-three parts: sugar, phosphate, base

RNA STRUCTURE

-Single Stranded-uses uracil, adenine, cytosine, and guanine-sugar is ribose

SIMILARITIES AND DIFFERENCES

SIMILARITES

Both have 4 bases They both have A, G, C Same three parts of the nucleotide:

sugar, phosphate, base Both have a backbone
