Because they cannot rotate, each peptide bond holds 6 atoms in a plane.

However, most possible angles of Phi (φ) and Psi (ψ) are impossible due to clashes

between atoms. These balls are much smaller than the atoms they represent.

Neurons generally have four important zones:

A dendritic zone, where multiple local potential changes generated by synaptic connections are integrated. a site where propagated action potentials are generated. an axonal process that transmits propagated impulses to the nerve endings the nerve endings, where action potentials cause the release of synaptic transmitters.

X-Linked Recessive Traits 

X-linked recessive traits appear more often in males than in females and are not passed from father to son.

Example – Hypophosphatemia , Rett syndrome
