1.1.10 The phosphate group is esterified to the-OH group on the 5 carbon of the deoxyribose rin g l..11A nucleotide lacking the phosphate part is called a nucleoside. 1.1.12 The four nucleoside units in dna are called deoxyadenosine, deoxyguanosine, deoxythymidine, and deoxycytidine. 1.1.2 The nitrogenous base can be adenine (A), guanine(G), cytosine(C), or thymine(T) (uracil (U) in RNA
1.1.10 The phosphate group is esterified to the -OH group on the 5’ carbon of the deoxyribose ring. 1.1.11 A nucleotide lacking the phosphate part is called a nucleoside. 1.1.12 The four nucleoside units in DNA are called deoxyadenosine, deoxyquanosine, deoxythymidine, and deoxycytidine. 1.1.2 The nitrogenous base can be adenine (A), guanine (G), cytosine (C), or thymine (T) (uracil (U) in RNA)
11.13 The four nucleotide units in dna are called deoxyadenine 5-monophosphate(dAMP, or deoxyadenylate), deoxyguanosine 5 monophosphate(dGMP, or deoxyguanylate), deoxythymidine 5-monophosphatedTMP, or deoxythymidylate), and deoxycytidine 5 monophosphate(dcMP, or deoxycytidylate)
1.1.13 The four nucleotide units in DNA are called deoxyadensine 5’-monophosphate (dAMP, or deoxyadenylate), deoxyguanosine 5’- monophosphate (dGMP, or deoxyguanylate), deoxythymidine 5’-monophosphate (dTMP, or deoxythymidylate), and deoxycytidine 5’- monophosphate (dCMP, or deoxycytidylate)
1.2 RNA also consists of four different kinds of ribonucleotides 1.2.1 Each ribonucleotide unit is also made of three parts: a nitrogenous base, a pentose, and a phosphate group. 1.2.2 The base part is adenine, guanine, cytosine or uracil. 1.2.3 Uracil exists only in RNA, and thymine only in DNA

1. 2. 4 The pentose part is a ribose (without being deoxygenated at the2’ position)inisβ- furanose form(as deoxyribose in deoxyribonucleotides). 1.2.5 The bases and the phosphate group are covalently linked to the ribose ring in the same ways as in deoxyribonucleotides 1.2. 6 The four nucleoside units in rna are called adenosine, guanosine, cytidine, and uridine (without deoxy- suffix); and the nucleotide units are amp gmp cmp and ump
1.2.4 The pentose part is a ribose (without being deoxygenated at the 2’ position) in its bfuranose form (as deoxyribose in deoxyribonucleotides). 1.2.5 The bases and the phosphate group are covalently linked to the ribose ring in the same ways as in deoxyribonucleotides. 1.2.6 The four nucleoside units in RNA are called adenosine, guanosine, cytidine, and uridine (without deoxy- suffix); and the nucleotide units are AMP, GMP, CMP, and UMP
