| (d) A deoxyribonucleoside-Deoxyguanosine | (e) A deoxyribonucleotide-Thymidine triphosphate |
Explanation of Solution
The structure of Adenosine and uridine are as follows:
Adenosine Uridine
Both are ribonucleoside as they contain ribofuranose attached by glycosidic bond to the purine nucleoside.
The structure of Cytidine 5'-monophosphate and guanosine 5'-diphosphate are as follows:
Cytidine 5'-monophosphate Guanosine 5'-diphosphate
The nucleoside cytidine and guanine are attached to phosphoric acid through ester linkage, thus, they form a nucleotide. There is also a pentose sugar ribose hence, they are classified as a ribonucleotide. There is one phosphate group in cytidine 5'-monophosphate and two phosphate groups in guanosine 5'-diphosphate.
Guanine and thiamine both are nucleobase, as they are nitrogen containing bases. They are found in nucleic acids DNA and RNA.
The structures are as follows:
Guanine Thymine
Deoxyguanosine and deoxyuridine are deoxyribonucleoside as they contain deoxyribose without phosphate group.
The structures are as follows:
Deoxyguanosine Deoxyuridine
Deoxycytidine 5'triphosphate and thymidine triphosphate are deoxyribonucleotide as they contain deoxyribose with phosphate group attached to nucleoside.
The structures are as follows:
Deoxycytidine 5'triphosphate Thymidine triphosphate
