DESCRIPTION
TRANSCRIPT
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
