Mrs. Wharton’s Science Class DNA

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- cytosine G- Guanine A- Adenine T- Thymine

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

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 DNA Thymine Cytosine
