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.
what are centrioles?
Centrioles are found in most of the eukaryotic cells.
Centrioles are surrounded by pericentriolar material in a cell ,together they form centrosome.
Definition
Centrioles are cylinderical shaped organelle that are mainly composed of tubulin protein.
Centrioles are made up of 9 set of microtubule triplets which are arranged in cylinderical shape. They are perpendicular and found in pairs , that is angle between two centrioles is 90°.
