DNA is a nucleotide polymer, or polynucleotide. Each nucleotide contains three components: A five carbon sugar A phosphate molecule A nitrogen-containing base. The sugar carbon atoms are numbered 1 to 5. The nitrogenous base attaches to base 1, and the phosphate group attaches to base 5. DNA...
Themoleculesthat form the basic modular structure of thedouble helixof theDNAmolecule. A nucleotide consists of three molecules — a sugar, a phosphate group, and a molecule called abase. If the double helix is a twisted ladder, the sugar and phosphates form the sides of the ladder and pairs...
Nucleotides are a type of monomer formed from a sugar, a phosphate or phosphate group, and a nitrogenous base. Nucleotides are named after the nitrogenous base they include. For example, the nucleotide thymine gets its name because it includes thymine as its nitrogenous base. ...
Each nucleotide is composed of a phosphate group, a sugar group, and a nitrogen base, and it is the order of the bases that give an organism its genetic code. There are two strands of nucleotides that coil around each other to form a double helix structure....

In a DNA chain, all of the 3' and 5' groups of pentose sugar are involved in phosphodiester bonds except for the first and last nucleotide in the chain. The first nucleotide of the chain has an intact 5' phosphate group i.e. it is not bound to any other nucleotide and the last ...
The meaning of NUCLEOTIDE is any of several compounds that consist of a ribose or deoxyribose sugar joined to a purine or pyrimidine base and to a phosphate group and that are the basic structural units of nucleic acids (such as RNA and DNA).
An example of a nucleoside analog would be one in which the label is linked to the base and there is no phosphate group attached to the sugar molecule. Although the base is usually referred to as a purine or pyrimidine, the skilled person will appreciate that derivatives and analogs are ...
When a phosphate group is linked to '5' OH of deoxyadenosine by phosphodiester linkage , a corresponding nucleotide is formed, which is View Solution Go through the following statements: (i) In RNA the uracil is found in place of 5-methyl uracil ...
1. A monomer of the formula: wherein:Bx is a heterocyclic base; T1 is OH or a protected hydroxyl group; T2 is an activated phosphorus group or a linking moiety attached to a solid support; T3 is H, OH, a protected hydroxyl or a sugar substituent group; said monomer having at least...
