1. D.N.A. DeoxyriboNucleic Acid
A molecule that contains our genetic information
Is found in the nucleus of almost all cells wound up into chromosomes.

2. DeoxyriboNucleic Acid
Double Helix (Twisted Ladder)
Double stranded
Made of Nucleotides: Sugar, Phosphate, Base
Has 4 nitrogen bases: Adenine, Guanine, Thymine, Cytosine
Combination of these bases (order) is what makes up our traits

3. Nucleotides

4. NUCLEOTIDES

5. Base Pair

6. Base Pair Complete the DNA strand T A C G C C C G T T A T C A T A
Hydrogen
Bonds!!!

7. Purines (Adenine, Guanine)
Pyrimidines (Thymine, Cytosine)

8. Replication Why Replicate (copy)? STEPS TO COPY DNA: DNA UNWINDS
DNA UNZIPS
BASE PAIRS ARE ADDED TO BOTH STRANDS
2 NEW DNA MOLECULES

9. Replication

10. DNA molecule
Base Pairing
Replication

11. RNA Ribonucleic acid RNA is a messenger for DNA.
RNA takes the genetic information from DNA and takes it to the ribosomes where it makes the proteins

12. 3 differences between RNA and DNA
1. RNA = ribose (does have oxygen)
DNA – deoxyribose (does not have oxygen)
2. RNA has a single strand
DNA has a double strand
3. RNA has uracil as a base instead of Thymine like DNA has 2

13. RNA 3 types messenger RNA – takes info from nucleus to ribosome
transfer RNA – transfers amino acids to ribosome
Ribosomal RNA – makes up ribosomes
