A proton is a subatomic particle with a positive electrical charge that found in the nucleus of an atom. The particle has an opposite and equal to that of the electron.
Rutherford discovered these positive charge particles and termed as a proton for the first time. The total number of protons in an element's nucleus is considered as the atomic number.
Telophase II begins after the separation of sister chromatids. In this phase individual chromosomes reach at pole. Nuclear membrane starts getting formed around them and cytokinesis takes place. Cytokinesis is the division of cytoplasm.
This results in the formation of four daughter cells which are haploid.
