Biomolecule: Nucleic Acids UNIT 6 Biomolecule: Nucleic Acids

UNIT 6 Deoxyribose Nucleic Acid (DNA): A-T G-C

DNA 6 There are 4 nucleotides named after their nitrogenous bases: UNIT 6 DNA There are 4 nucleotides named after their nitrogenous bases: Adenine (A) always pairs with thymine (T) aunt = tia

DNA 6 There are 4 nucleotides named after their nitrogenous bases: UNIT 6 DNA There are 4 nucleotides named after their nitrogenous bases: Adenine (A) always pairs with thymine (T) aunt = tia Guanine (G) always pairs with cytosine (C) gato = cat

DNA 6 There are 4 nucleotides named after their nitrogenous bases: UNIT 6 DNA Hydrogen bonds There are 4 nucleotides named after their nitrogenous bases: Adenine (A) always pairs with thymine (T) aunt = tia Guanine (G) always pairs with cytosine (C) gato = cat The bases are held together by weak hydrogen bonds.

DNA 6 There are 4 nucleotides named after their nitrogenous bases: UNIT 6 DNA Hydrogen bonds There are 4 nucleotides named after their nitrogenous bases: Adenine (A) always pairs with thymine (T) aunt = tia Guanine (G) always pairs with cytosine (C) gato = cat The bases are held together by weak hydrogen bonds.

They are antiparallel (going in opposite directions). UNIT 6 DNA There are 4 nucleotides named after their nitrogenous bases: Adenine (A) always pairs with thymine (T) aunt = tia Guanine (G) always pairs with cytosine (C) gato = cat The bases are held together by weak hydrogen bonds. One strand goes in one direction and another strand goes in another direction. They are antiparallel (going in opposite directions).

DNA (Deoxyribose Nucleic Acid): DNA is double-stranded to help make it more stable. DNA is known as the Double-helix.

Nucleotide Classification: Purines & Pyrimidines Purines: Two-carbon Nitrogen ring bases. Pyrimidines: One-carbon Nitrogen ring bases Purine Nucleotides: Adenine Guanine Pyrimidine Nucleotides (Pyramids C.U.T.) Cytosine Uracil (we will cover this next week) Thymine

Chargaff’s Rule Chargaff’s Rule: In DNA, the quantity of Adenine (A) equals the quantity of Thymine (T). Moreover, the quantity of Guanine (G) equals the quantity of Cytosine (C). Number of A base pairs = Number of T base pairs A=T Number G base pairs= Number of C base pairs G=C

Build a Human Nucleotide UNIT 6 Build a Human Nucleotide Each of you will get either a Phosphate, Sugar, or Base (A, T, G, C) and we will build a Human Nucleotide 2 1 3 3 1 2
