The three subunits of a nucleotide are a nitrogenous base, a sugar and a phosphate group. Nucleotides are the building blocks of DNA and RNA molecules.
Nucleotides are joined from the 3′ carbon of the sugar in one nucleotide to the 5′ carbon of the sugar of the adjacent nucleotide. The 3′ and the 5′ ends are chemically very distinct and have different reactive properties. During DNA replication, new nucleotides are added only to the 3′ OH end of a DNA strand.
DNA and RNA: A nucleotide is made up of three components: a nitrogenous base, a pentose sugar, and one or more phosphate groups.Carbon residues in the pentose are numbered 1′ through 5′ (the prime distinguishes these residues from those in the base, which are numbered without using a prime notation).
Nucleotides are the basic units of nucleic acids (DNA and RNA). Nucleic acids are biomolecules essential for all forms of life. A nucleotide has 3 components: 1. Pentose sugar> 2. Nitrogenous base 3. Phosphate sugar. Pentose Sugar. It is a monosaccharide with 5 carbon atoms. It forms the backbone of polynucleotide chain. It is also of 2 types. 1.
1.The basic unit of the DNA molecule is (1) a nucleotide (2) an amino acid (3) a phosphate group (4) a nitrogen base 2.The coded information of a DNA molecule is determined by the (1) sequence of amino acids (3) sequence of the nitrogenous bases (2) number of ribose units (4) sequence of the sugar-phosphate units

A nucleotide may have one, two or three phosphate groups. The nomenclature of a nucleotide helps us to identify its structure as the name of a nucleotide is dependent on all of its components. In general, the name of nucleoside is followed by the number of phosphate groups in the name of a nucleotide.

DNA polymerase; deoxynucleoside triphosphates (dNTPs); buffer solution. DNA template in PCR amplification. DNA from a variety of sources may be used as the supplier of the DNA template for 3 basic steps of the polymerase chain reaction. PCR is a highly sensitive technique and requires only one or two DNA templates for successful amplification.
3. What is the difference between DNA and RNA Nucleotides. What is a DNA Nucleotide. A DNA nucleotide is the monomer nucleotide, which can be found in DNA. It contains deoxyribose as the pentose sugar, which is attached to a nitrogenous base at its 1′ carbon and a phosphate group at its 5′ carbon. Deoxyribose is a monosaccharide, which is ...
