1 Mrs. Wharton’s Science Class
DNA

2 Deoxyribonucleic Acid
DNA- in chromosomes of the cell. Instructions for the cell. Genetic material. Its in a shape of a DOUBLE HELIX- or twisted ladder

3 Nucleotides Consists of sugars, phosphates and nucleic acids
The order of nitrogen bases along a gene forms a genetic code that specifies what type of protein will be produced.

4 Nitrogen bases for DNA C- cytosine G- Guanine A- Adenine T- Thymine

5 RNA- Ribonucleic acid Decides what proteins are built in all living things RNA- single helix structure RNA and DNA are held together by nucleic acids Uracil instead of thymine Same rules as DNA

6 What do they do? DNA holds on to instructions for cell ( head coach)
RNA sends directions to other cell parts ( Team leader)

7 RNA vs DNA RNA Uracil Cytosine Adenine Guanine DNA Thymine Cytosine

DNA: the blueprint of life. Where do you get your DNA? DNA is passed from parent to offspring. Where do we find DNA? DNA is in the nucleus of every cell.
