Genetic exchange also happens between distantly related organisms by horizontal gene transfer, or HGT.

HGT is particularly important to prokarytotes and is the most common way by which they acquire new genes.

The labyrinth has three components: 

Cochlea (containing receptors for hearing)

Semicircular canals (containing receptors that respond to head rotation)

Otolith organs (containing receptors that respond to gravity and head tilt)

Two beta strands are connected by a long region containing a helix

These beta strands form parallel beta-sheets

The loop regions connecting sheet and helix can have different length

The helix axis is generally parallel to beta-sheets

Three secondary structures are stabilized by hydrophobic interactions
