DNAMrs. Wharton’s Science Class

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

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.

Nitrogen bases for DNA

C- cytosineG- GuanineA- AdenineT- Thymine

RNA- Ribonucleic acid

Decides what proteins are built in all living things

RNA- single helix structureRNA and DNA are held together

by nucleic acidsUracil instead of thymineSame rules as DNA

What do they do?

DNA holds on to instructions for cell ( head coach)

RNA sends directions to other cell parts ( Team leader)

RNA vs DNA

RNA

Uracil Cytosine Adenine Guanine
