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

8. 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.

9. 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.

10. 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).

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

12. 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

13. 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
