Nucleotides
It is an organic molecule made up of three basic components- a nitrogenous base, phosphate,and pentose sugar. The nucleotides are important for metabolic reactions andthe formation of DNA (deoxyribonucleic acid) and RNA (ribonucleic acid).
Nucleic Acids
Nucleic acids are essential biomolecules present in prokaryotic and eukaryotic cells and viruses. They carry the genetic information for the synthesis of proteins and cellular replication. The nucleic acids are of two types: deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). The structure of all proteins and ultimately every biomolecule and cellular component is a product of information encoded in the sequence of nucleic acids. Parts of a DNA molecule containing the information needed to synthesize a protein or an RNA are genes. Nucleic acids can store and transmit genetic information from one generation to the next, fundamental to any life form.
The Nucleosome Is the Fundamental Unit
of _____________Packaging
Chromosomes are present inside the nucleus of a cell which contains DNA in a condensed form.
The Nucleosome Is the Fundamental Unit of chromatin Packaging.
Nucleosome is the structural unit which consists of part of DNA wrapped around core of histones which are set of eight proteins so as to form chromatin and hence the DNA to become condensed into smaller volume inside the nucleus.
The chromatin are fine fibres composed of DNA, some proteins and transcribing RNA. The proteins associated with chromatin are mainly histone proteins. These are positively charged basic proteins mainly composed of Lysine and arginine.
