Although many people refer to the rotator cuff as a general area in the shoulder, your rotator cuff itself is a group of 4 tendons located at the top of your humerus. These tendons are called the subscapularis tendon, the supraspinatus tendon, the infraspinatus tendon, and the teres minor tendon.lthough many people refer to the rotator cuff as a general area in the shoulder, your rotator cuff itself is a group of 4 tendons located at the top of your humerus.

Genomic imprinting is the epigenetic phenomenon by which certain genes are expressed in a parent-of-origin-specific manner. If the allele inherited from the father is imprinted, it is thereby silenced, and only the allele from the mother is expressed.f the allele from the mother is imprinted, then only the allele from the father is expressed. Forms of genomic imprinting have been demonstrated in fungi, plants and animals.
In genes that undergo genomic imprinting, the parent of origin is often marked, or âstamped,â on the gene during the formation of egg and sperm cells. This stamping process, called methylation, is a chemical reaction that attaches small molecules called methyl groups to certain segments of DNA.nly a small percentage of all human genes undergo genomic imprinting. Researchers are not yet certain why some genes are imprinted and others are not. They do know that imprinted genes tend to cluster together in the same regions of chromosomes.
