2. Nucleic Acid

3. Nucleic Acids Examples: – RNA (ribonucleic acid) single helix – DNA (deoxyribonucleic acid) double helix Structure: – monomers = nucleotides RNADNA

4. proteins DNA Nucleic Acids Function: – genetic material stores information – genes – blueprint for building proteins » DNA  RNA  proteins transfers information – blueprint for new cells – blueprint for next generation

5. A A A A T C G C G T G C T Genes (DNA) are needed to run bodies every day … to make you and me … to make new cells … to make babies!

6. Nucleic acids Building block = nucleotides  Nucleotides are made of 3 parts  Phosphate group, sugar, and nitrogen base  5 different nucleotides  different nitrogen bases  A, T, C, G, U nucleotide – nucleotide – nucleotide – nucleotide phosphate sugar N base Nitrogen bases I’m the A,T,C,G or U part!

7. Nucleotide chains Nucleic acids nucleotides chained into a polymer Deoxyribonucleic acid (DNA Structure) - Double (two) strands - Double helix - Nucleotides : Adenine (A) Thymine (T) Guanine (G) Cytosine (C) A bonds with T G bonds with C phosphate sugar N base phosphate sugar N base phosphate sugar N base phosphate sugar N base Complimentary Base pairing

8. Nucleotide chains Ribonucleic acid (RNA Structure) single-sided Nucleotides :Adenine (A) Uracil (U) Guanine (G) Cytosine (C) A bonds with U G bonds with C phosphate sugar N base phosphate sugar N base phosphate sugar N base phosphate sugar N base RNA

9. Ticket to leave Nucleotides make what polymer? Draw and label a nucleotide.
