The correct answer is:
A nucleoside tetraphosphate yields upon complete hydrolysis one nucleobase, one sugar, and four phosphates.
A tetranucleotide yields four bases, four sugars, and at least three phosphates.
Nucleosides are glycosylamines that can can be defined as a nucleotides without a phosphate group. So, nucleoside is composed of a nitrogenous base covalently attached to a sugar (ribose or deoxyribose) without the phosphate group. On the other hand, nucleotide is composed of a nitrogenous base, a sugar and one to three phosphate groups.
Answer:
The correct answer is option A which is a nucleoside tetraphosphate yields upon complete hydrolysis one nucleobase, one sugar, and four phosphates. A tetranucleotide yields four bases, four sugars, and at least three phosphates.
Explanation:
- nucleoside = Nitrogenous base + ribose sugar
- nucleoside tetraphosphate = nucleoside + 4 atoms of phosphate.
- That is why on hydrolysis nucleoside tetraphosphate yields one nucleobase, one sugar, and four phosphates.
- Nucleotide = Nitrogenous base + ribose sugar + 3 phosphate.
- Tetra nucleotide = 4 Nucleotide.
- That is why on hydrolysis, yield is 4 bases, 4 ribose sugar and at least 3 phosphate.
