Nucleic Acids• DNA

deoxyribonucleic acid

• RNA ribonucleic acid

Page 3: Nucleic Acids. Elements Nucleic Acids Contain C, H, O,N, P

Elements Nucleic Acids Contain

•C, H, O,N, P

Page 4: Nucleic Acids. Elements Nucleic Acids Contain C, H, O,N, P

Nucleotides: Monomers of Nucleic Acids

nitrogenous

Page 5: Nucleic Acids. Elements Nucleic Acids Contain C, H, O,N, P

Nucleic Acids• Sugar + phosphate + nitrogenous base

Page 6: Nucleic Acids. Elements Nucleic Acids Contain C, H, O,N, P

Nucleotides: 3 parts

• 5-C sugar• Phosphate Base• Nitrogenous Base A, T, C, G

Sing Along Songs - Row, Row, Row Your Boat

• We love DNA• Made of nucleotides• Sugar, Phosphate, and a base• Bonded down one side

• Adenine with thymine make a lovely pair

• Cytosine without guanine would feel very bare.

4 Nitrogenous Bases

• A = adenine• T = thymine• C = cytosine• G = guanine

Page 9: Nucleic Acids. Elements Nucleic Acids Contain C, H, O,N, P

Base Pairing

•A – T•C - G

RNA and DNA

• RNA is single stranded

• DNA is double stranded

SNEAK PREVIEW

• DNA molecule• Sections of it are genes• Genes are the codes that

make specific amino acids that link together to make a protein
