What contains a sugar a base and a phosphate group?
nucleotides that are the building blocks of nucleic acids are made up of sugar, a nitrogen base and phosphate group
Is phosphorus a nucleotide?
Yes, nitrogen is found in nucleic acids in the form of nitrogenous base. Actually, nucleic acids (DNA and RNA) are linear polymers of nucleotides (a purine or pyrimidine nitrogenous base + a pentose sugar + a phosphate group).
What is the Sugar phosphate backbone of the DNA?
THE BACKBONE OF DNA IS FORMED OF NUCLEOTIDES LINKED BY PHOSPHODIESTER BOND.A nucleotide consists of following three compounds1. Pentose sugar :- It is a 5 membered ring sugar. Out of these 5 members four are carbon and one is oxygen. The pntose sugar in case of DNA is deoxyribose.2. Nitrogen Base :- It is a nitrogen containg basic ring compound. They are broadly classified into 2 categories-Pyrines and pyrimidines. These are further divided into 5 nitrogen bases. They are Adenine,Guanine,Cytocine, Thymine, Uracil. Out of these 5 bases only four are present in DNA and only one occurs in it at a time.DNA does not have Uracil. The 7th or 9th nitrogen of the nitrogen base are linked to the 1st carbon of pentose sugar by glycosidic bond3. Phosphate group :-It is a derivative of phosphoric acid and is attached to 5th carbon of pentose sugar by ester bond formed by dehydration synthesisTwo nucleotides in DNA are liked by phospho diester bond formed between -OH of phosphate group of one nucleotide and 3rd carbon of pentose sugar ofadjacent nucleotide.
What is the end product of the pentose phosphate pathway?
End product of Pentose Phosphate Pathway is NADPH and ribose-5-phosphate NADPH: for biosynthesis of lipid ribose-5-phosphate: building block for nucleic acid synthesis
What are three compounds of a DNA nucleotide?
The three components of DNA are: base, sugar, and phosphate. A molecule of DNA consists of two strands. Each strand is a linear series of nucleotides. Each nucleotide consists of a base (a purine or pyrimidine), a pentose (five-carbon sugar), and a phosphate group. The sugar is between the base and the phosphate. In a strand, nucleotides are combined through their sugars and phosphates, in such a way that alternating sugars and phosphates form a sugar-phosphate backbone. The bases project at right angles to this backbone.
What constitue the backbone structure of nucleic acid chains?
phosphate and sugar
What is nucleic acid made of?
A phosphate group, a ribose sugar, or deoxyribose sugar backbone and a nitrogenous base.
Which linkage forms the backbone of a nucleic acid?
A chain of sugar and phosphate groups, linked through phosphodiester bonds is the backbone of a nucleic acid.
What does a nucleic acid DNA contain?
Dna consists of of a phosphate and [ribose] sugar backbone with the four nucleic acid bases proffered laterally as the information containing components.
What is the backbone of nucleic acid polymers composed of?
All marcomolecules (including nucleic acids) have a backbone of carbon.
What are three groups nucleic acid is made up of?
A sugar ( ribose, or deoxyribose ) and phosphate group backbone and one of five nitrogenous bases.
Why is nucleic acid called so although it has no acidic group?
The phosphate backbone of nucleic acids is an ionizable group which has an acidic pKa. This is the basis of the "acid" in "nucleic acid."
What parts of a nucleotide make up the backbone of a nucleic acid-?
Nucleic acids are made up of monomers called nucleotides, which consist of; a sugar, a phosphate part and an N-containing base.
Subunits of nucleic acids?
The monomers of nucleic acid polymers are the nucleotides. Each is composed of a sugar-phosphate backbone and one of four bases as a side group. In RNA the sugar is ribose, in DNA the sugar is deoxyribose.
What are the smaller molcecules that make up nucleic acid called?
The backbone of a nucleic acid is made up of alternating sugar and phosphate molecules bonded together to these are attached the molecule making the rungs of the double helix ladder the Nucleotides.
What part of nucleotide make up the backbone of nucleic acid?
Pentose sugars and Phosphate groups
What parts of the nucleotide make up the backbone of the nucleic acid?
Pentose sugars and Phosphate groups
