What is the structure of nucleoside triphosphate?
What is the structure of nucleoside triphosphate?
A nucleoside triphosphate is a molecule containing a nitrogenous base bound to a 5-carbon sugar (either ribose or deoxyribose), with three phosphate groups bound to the sugar.
What is the difference between ATP and nucleoside triphosphate?
A) the nucleoside triphosphates have the sugar deoxyribose; ATP has the sugar ribose. ATP is a ribose nucleotide triphosphate. DNA or Deoxyribose Nucleic Acid is synthesized by polymerization of deoxyribose nucleotide triphosphates.
Which of the following is are a nucleoside triphosphate?
Nucleoside triphosphates are monomers of RNA and DNA and are made up of a nucleoside and 3 phosphate groups. A nucleoside is a molecule containing a nitrogenous base and a sugar, either ribose or deoxyribose. The nucleoside triphosphates containing ribose are ATP, CTP, GTP, UTP and m5UTP.
What are deoxynucleotide triphosphates?
Deoxynucleotide triphosphates (dNTPs) are the nucleoside triphosphates containing deoxyribose. dNTPs are the essential building blocks of nucleic acid molecules, and as such are necessary components of PCR mixes as no new amplified DNA could be generated without them.
Why are ribonucleoside triphosphates the monomers?
Why are ribonucleoside triphosphates the monomers required for RNA synthesis rather than ribonucleoside monophosphates? Ribonucleoside triphosphates have high potential energy, making the polymerization reaction exergonic. DNA is transcribed to give RNA a copy.
What is a deoxynucleotide triphosphate?
What does Triphosphates mean?
Definition of triphosphate : a salt or acid that contains three phosphate groups — compare atp, gtp.
What does a Deoxynucleotide consist of?
A deoxynucleotide in biological terms is a component of deoxyribonucleic acid, DNA. A deoxynucleotide is made up of an organic base, a ribose sugar and phosphate. DNA polymerase requires deoxynucleotides in their triphosphate (containing three phosphates) form in order for DNA synthesis to take place.
What is the structure of a nucleoside triphosphate?
The first phosphate group linked to the sugar is termed the α-phosphate, the second is the β-phosphate, and the third is the γ-phosphate. Schematic showing the structure of nucleoside triphosphates. Nucleosides consist of a 5-carbon sugar (pentose) connected to a nitrogenous base through a 1′ glycosidic bond.
What is the first phosphate group in a triphosphate?
The first phosphate group linked to the sugar is termed the α-phosphate, the second is the β-phosphate, and the third is the γ-phosphate. Schematic showing the structure of nucleoside triphosphates.
What is the structure of ATP?
The structure of ATP is a nucleoside triphosphate, consisting of a nitrogenous base (adenine), a ribose sugar, and three serially bonded phosphate groups. ATP is commonly referred to as the “energy currency” of the cell, as it provides readily releasable energy in the bond between the second and third phosphate groups.
What is the difference between nucleotides and phosphates?
Nucleotides are nucleosides covalently linked to one or more phosphate groups. To provide information about the number of phosphates, nucleotides may instead be referred to as nucleoside (mono, di, or tri) phosphates.
