Ch8 Nucleotides and Nucleic Acids
Functions of Nucleotides and Nucleic Acids
Nucleotides and Nucleosides-重要差別:前者有phosphate group,後者沒有
Phosphate Group
Nitrogenous Base
A,C,G,T,U彼此之間皆可以形成氫鍵
Watson-Crick 發現最常見的鹼基配對:A配T 和 C配G
嘌呤
嘧啶
Tautomerism
重要需要記得的東西(結構、命名、特徵)
β-N-Glycosidic Bond(醣苷鍵)
syn 和 anti form 的差別
Minor Nucleosides
in DNA
in RNA
Polynucleotides
DNA
類型
.
.
BDNA(最常見)
ZDNA
ADNA
雙股互補
DNA複製(Daughter strands和Parent strands)
DNA Denaturation
.
隨著溫度升高,先部分解旋,再全部解旋
Mutagenesis
氧化損害和化學物質誘發的突變
.
UV誘發的突變
.
自發性突變(Spontaneous Mutagenesis)
Depurination
Deanimation
RNA
Hydrolysis of RNA
RNA在鹼性條件下不穩定
可以用來水解RNA的三種RNA:(1)sS-RNase(2)RNase P(3)Dicer
Mechanism of Base-catalyzed RNA Hydrolysis
mRNA
Palindromic Sequences(迴文序列)-重要性:穩定結構
