(a)
Interpretation:
The bases present in the
Concept Introduction:
The five common bases in the
(b)
Interpretation:
In the given structure,5 and 3 ends need to be labeled.
Concept Introduction:
Both DNA and RNA are formed by joining3'-OH (3 end) group of one nucleotide and 5'- phosphate (5 end) of a second nucleotide resulting in a phosphodiester linkage.
(c)
Interpretation:
Thethree- or four-letter abbreviation for the two nucleotides needs to be determined.
Concept Introduction:
Nucleotides are nucleic acids which are unbranched
(d)
Interpretation:
Whether the given molecule is ribonucleotide or deoxyribonucleotide needsto be determined.
Concept Introduction:
Nucleotides are nucleic acids which are unbranched polymers containing repeating monomers. The two types of nucleic acids are DNA and RNA. There are three components of the DNA and RNA containing the nucleotide monomers: a monosaccharide, a nitrogen-containing base, and a phosphate group.
(e)
Interpretation:
The dinucleotide needs to be named.
Concept Introduction:

- label the acetal and hemiketal moieties and peptride bonds. Indicate and name the bond that links the two saccharides in the disaccharide. Sketch the reaction of hydrolysis of the peptide, clearly drawing the reactants and products. Using one-letter codes, identify the dinucleotide sequence and state whether this is a DNA or RNA dinucleotide. Sketch the reaction of formation of the dinucleotide from its constituent nucleotides, clearly drawing reactants and products, and state which kind of reaction it is.arrow_forwardSuppose that 28% of the nucleotides in a DNA molecule are deoxythymidine 5'-monophosphate, and that during DNA replication the percentage amounts of available nucleotide bases art 22% A, 22% C, 28% G. and 28% T.
