On the laboratory bench right in front of you, there is a bone. You can tell that it has an articular surface that is smooth and just slightly concave. This skeletal feature would be referred to as a Facet.

<h3>What is the composition of human bone?</h3>

A transcription factor collagen forms the structure of bones, and calcium phosphate, a mineral, gives the framework strength and hardness. When other body parts require calcium, bones release some of the calcium they have stored into the blood.

<h3>Why are bones so durable?</h3>

A living, developing tissue is bone. Collagen, a polypeptide that provides a soft structure, and calcium, a mineral that gives strength and hardness, make up the majority of its composition. Together, these factors give bone the strength and flexibility it needs to withstand stress.

The autosomal dominant trait may en defined as the trait that can express itself even in the heterozygous condition and in the homozygous dominant condition as well.
