Acidic Amino acids:
-Side chains are generally negative in charge owing to the prescence of a carboxyl group, which is usually dissociated (ionized) at cellular pH.
-(All amino acids have carboxyl groups and amino groups; the terms acidic and basic in this context refer only to groups on the side chains.)

-Aspartic acid
-Glutamic acid
Basic Amino acids:
-Have amino groups in their side chains that are generally positive in charge.
-All amino acids have carboxyl groups and amino groups; the terms acidic and basic in this context refer only to groups on the side chains.)

-Lysine
-Arginine
-Histidine
Nucleic acids:
Two types are DNA and RNA
Structure of Nucleic acids:
-Polymers called Polynucleotides made up of monomers called nucleotides.
-Nucleotide is composed of three parts: a nitrogenous base, a pentose (five-carbon sugar), and a phosphate group.
-Polynucleotides are formeb when adjacent nucleotides are joined by covalent bonds called phosphodiester linkages between the -OH group on the 3' Carbon of one nucleotide and the phosphate on the 5' carbon of the next.
Nitrogenous bases:
Pyrimidines:
-Cytosine
-Thymine (in DNA)
-Uracil (in RNA)

Purines:
-Adenine
-Guanine
Purine vs. Pyrimidine nitrogenous bases:
-Pyrimidine is a single ring structure.

-Purines are larger and have a bicyclic structure.
(Nucleotides) Deoxyribose vs. Ribose
Deoxyribose has one less oxygen than Ribose. (Seems to be on the 2nd carbons.)
DNA Double Helix:
-Two polynucleotides, or strands, as they are called, are held together by hydrogen bonds between the paired bases.
-Adenine can pair only with thymine.
-Guanine can pair only with cytosine.
-It seems that Purines can only pair with Pyrmidines,(not with other Purines) Same goes for pyrimidines, cant pair with other pyrimidines.
