1Polymers in which repeating unit is nucleotide
Nucleic Acids
2Where are nucleic acids found? nature?
Found in nucleus and are acidic in nature
3Two Types of Nucleic Acids
DNA: Deoxyribonucleic Acid and RNA: Ribonucleic Acid
4Where can you find DNA
Found within cell nucleus
5Function of DNA
Storage and transfer of genetic information
6Where can you find RNA
Occurs in all parts of cell
7Function of RNA
synthesize the proteins
8What does a nucleotide contain
Pentose Sugar (monossacharide), Phosphate group, and a heretocyclic base
9What type of pentose sugar is present in RNA
Ribose
10What type of pentose sugar is present in DNA
2- deoxyribose
11Structural difference in pentose sugar in RNA and DNA
OH group present on carbon 2’ in ribose
H atom present on carbon in 2-deoxyribose
12What are the 5 bases
thymine (T), cytosine (C), and uracil (U), adenine (A) and guanine (G)
13Three pyrimidine derivatives
thymine (T), cytosine (C), and uracil (U)
14Two purine derivatives
adenine (A) and guanine (G)
15 bases found in both DNA and RNA
Adenine (A), guanine (G), and cytosine (C)
16found only in RNA
Uracil (U)
17found only in DNA
Thymine (T)
18The formation of a nucleotide from sugar, base, and phosphate
pentose sugar and nitrogenous base react to form a “Nucleoside”
Nucleoside reacts with a phosphate group to form a “Nucleotide”
19 8 nucleosides associated with nucleic acid chemistry
Four ribonucleosides– RNA
Four deoxyribonucleosides – DNA
20Nomenclature For pyrimidine bases
suffix -idine is used (cytidine, thymidine, uridine)
21Nomenclature For Purine bases
suffix -osine is used (ddenosine, guanosine)
22Addition of a phosphate group to a nucleoside
Attached to C5” position through a phosphate-ester bond
Condensation reaction (H2O released)
Named by appending 5’-monophosphate to nucleoside name
23referred to as nucleic acid backbone
Sugar-phosphate groups
