## miRNA or microRNA Functions and Biogenesis

MicroRNAs (miRNA) are a class of small non-coding RNAs that involve in regulation of gene expression. lin-4 was the first discovered miRNA by Ambros and colleagues in C. elegans(Caenorhabditis elegans). After 7 years of the discovery of lin-4, Reinhart et al. reported lin-7( another miRNA in C. elegans). A unique characteristic of miRNAs is that … Read moremiRNA or microRNA Functions and Biogenesis

## Root modification examples and functions

Root The root is the underground part of a plant. Root develops from the radicle of the germinated seed. Important functions of the roots : Absorption of water and minerals. In anchoring the plant in the soil Important Characteristic of roots : The roots in the plants lack node. They are positively geotropic, negatively phototropic … Read moreRoot modification examples and functions

## Electric Dipole and Electric Field due to Dipole

An electric dipole is a pair of equal and opposite point charges that are separated by a short distance. Electric Dipole Moment The electric dipole moment is the product of the magnitude of one electric charge and the distance between the charges.SI unit of dipole moment is Coulomb-meter. Electric dipole formula, $p=(2a)q$ p= Dipole moment, … Read moreElectric Dipole and Electric Field due to Dipole
