Nucleic Acid Basics • Contain instructions to build proteins • 2 types: • DNA • RNA • Composed of smaller units called nucleotides • Monomer: Nucleotide • Polymer: Nucleic acid
Nucleotide Structure • Three parts • Sugar molecule • Phosphate group • Nitrogen base (1 of 4 types) • Nitrogen Base arrangement determines protein created
Monomers link to make polymers!Nucleic AcidsMonomer = NucleotidePolymer = Nucleic acid
DNA • Double Helix: 2 chains of nucleotides • DNA bases: Adenine, thymine, cytosine, guanine • A pairs with T • C pairs with G • DNA stores the info required to make a protein • Gene: section of DNA that codes for a protein
How many Nucleotides?
RNA • 1 chain of nucleotides • RNA bases: Adenine, uracil, cytosine, guanine • Copy the DNA code… deliver code to ribosome to make a protein
