Cortisol is a hormone that is considered as an endogenous mineralocorticoid that activates the sympathetic nervous system, it is said that its peak in blood in the body respects a schedule and it is at dawn, which makes us wake up at dawn.
This hormone once it diffuses through the cell membrane has its receptor and its action at the nuclear level, this is thanks to its butterflies properties that helps it to better diffuse the membranes and reach a binding site at the nuclear level. In this way it interferes with genetic coding and protein expression.
The longitudinal halves of a chromosome that has undergone replication are known as chromatids. They will not be called chromosomes until after they are separated during Mitosis. Mitosis distribute the chromatids to daughter cells as a cell divides. The chromosomes are initially replicated in cells undergoing Meiosis, as in preparation for the mitotic division, but then, these chromosomes are divided twice so that four daughter nuclei are produced, each having the haploid chromosome number.
