Nucleic Acids Nucleic acids provide the directions for building proteins. Two main types…  DNA – deoxyribonucleic acid  Genetic material (genes) that.

Structure Made of C, H, O, N, P What is the monomer for Nucleic Acids? Nucleotides! DNA – Double stranded (Double Helix) RNA – Single stranded.

Regents Biology Nucleic Acids Information storage

Regents Biology Nucleic Acid Functions  Function #1:  stores genetic material  genes DNA proteins  Function #2:  transfer genetic material

Regents Biology Nucleic Acids Only 2 Types of Nucleic Acids:  DNA (DeoxyriboNucleic Acid)  RNA (Ribonucleic Acid)

Regents Biology Nucleic Acids are made from Nucleotides  3 parts to every nucleotide:  nitrogen base  pentose sugar (5C)  ribose in RNA  deoxyribose in DNA  Phosphate group (PO 4 )

Regents Biology  5 different nucleotides  different nitrogen bases  adenine  thymine  cytosine  guanine  uracil nucleotide – nucleotide – nucleotide – nucleotide phosphate sugar N base Nitrogen bases I’m the A,T,C,G or U part! Nucleic Acids are made from Nucleotides

Regents Biology phosphate sugar N base phosphate sugar N base phosphate sugar N base phosphate sugar N base  2 strands of DNA helix are complementary  A – T and G – C Nucleic Acid polymer

Regents Biology That’s a big DNA molecule! Any questions?
