<span>A clone representing myostatin would be found in the genomic library made from muscle approximately one time out of every sixty thousand. Under the given conditions, the human genome and average insert size, the frequency of that particular type of clone can be estimated to be very near the probability of 1/60,000. This can be expressed either in fraction form or in descriptive words and maintain the same level of meaning.</span>
The main molecules present in the plasma membrane are<em><u> phospholipids</u></em>, those molecules are made of a polar, hydrophil end(glycerol with a phosphate group attached) and two non-polar, hydrophobe ends(two fatty acids rests). The cell identity is determined by <u><em>proteins </em></u>present in the membrane, a very important type of protein that determines the identity of a specific cell is called marker. The membrane fluidity is reduced by a lipid with a ring structure, <u><em>cholesterol</em></u>, this molecule belongs to a class of biomolecules called steroids.
The process of naming and grouping organisms is known as taxonomy. This naming system was started by Carolus Linnaeus. The system groups plants and animals by relationships and characteristics. Each organism is given a Latin name.
