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 are nitrogen bases attached to?
Nitrogen bases attach to deoxyribose sugar, in nucleotides.
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
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.
Which nitrogen base is missing in DNA?
Uracil.
What is the polymer of dna known as?
The monomer units of DNA are nucleotides, and the polymer is known as a "polynucleotide." Each nucleotide consists of a 5-carbon sugar (deoxyribose), a nitrogen containing base attached to the sugar, and a phosphate group.
What does nitrogen-containing base mean?
nitrogen-containing
What are 3 things a nucleotide is made up of?
the three components that make up a nucleotide are a phosphate,deoxyribose and a nitrogen base
What is subnits of DNA called?
nucleotides. nucleotides are made of a sugar-phosphate backbone and a nitrogen-containing base
Ribose is a type of?
a. nitrogen containing base b. amino acids c. sugar d. enzyme ~c. sugar =]
What is a makeup of nucleotide?
A 5-carbon sugar called deoxyribose, a phosphate group, and a nitrogenous (nitrogen-containing) base.
What is the makeup of a nucleotide?
A 5-carbon sugar called deoxyribose, a phosphate group, and a nitrogenous (nitrogen-containing) base.
What are the three things that make up Atp?
The ATP molecule is composed of three components. At the centre is a sugar molecule, ribose (the same sugar that forms the basis of RNA). Attached to one side of this is a base (a group consisting of linked rings of carbon and nitrogen atoms); in this case the base is adenine. The other side of the sugar is attached to a string of phosphate groups. These phosphates are the key to the activity of ATP.
What main things make up and ATP molecule?
nitrogen containing base, 3 phosphate groups and 5 carbon sugar
What does nitrogenous base mean?
nitrogen-containing

What are the monomer unit of DNA?
The monomer units of DNA are nucleotides. Each of these consist of a 5-carbon sugar which is deoxyribose, a nitrogen containing base attached to the sugar and a phosphate group.
