2What is DNA DNA stands for Deoxyribonucleic Acid DNA – The material inside the nucleus of cells that carries genetic information.
3Discovering the Structure of DNA Structure was discovered in 1953 by James Watson and Francis Crick
4Function of DNAStores genetic information that instructs the cell on what proteins to make and where to make themResponsible for determining all organism’s traits such as eye color, body structure, and cellular enzyme production (exact words from a previous TAKS test).
5The Components of DNADNA is a long molecule made up of repeating individual units called nucleotides.Nucleotides are made up of three parts:SugarPhosphate GroupNitrogenous Base
6Nitrogenous Bases DNA contains four nitrogenous bases: Adenine (A) Guanine (G)Cytosine (C)Thymine (T)
7Nucleotides Put Together = DNA DRAW THIS PART ON YOUR NOTES!
8Structure of DNA Phosphate Group & Deoxyribose Sugar Nitrogenous Bases Form the backbone or sides of the ladder.Nitrogenous BasesForm the “rungs” of the ladder or middle of the molecule.
9The Shape of DNADNA looks like a “twisted ladder” called a Double Helix.
