INTRODUTION

Catechol-O-methyl transferase (COMT) is an enzyme that plays a significant role in the metabolism of dopamine (DA) and amounts to approximately 60% or more of DA breakdown in the frontal cortex . The gene expressing the COMT enzyme could affect cognition and functioning of the brain via its action on dopaminergic function. A polymorphic variation occurs in the coding area of the COMT gene (a Guanine to Adenine replacement), changing the amino acid from valine (Val) to methionine (Met) at the codon position 158 (Val158Met) and consequently influencing the thermal tolerance and stability of the enzyme. Allelic discrepancies in enzyme ...

Abstract

This research paper will discuss the significant contribution of DNA fingerprinting in the criminal justice system for being able to provide a reliable basis for conviction. DNA fingerprint analysis is referred as an accurate indicator to determine the guilt and innocence of an accused. The history, importance and various DNA fingerprinting techniques shall be discussed. In addition, DNA fingerprinting is considered as more superior than other forensic science methods since the technology has improved over time. DNA fingerprinting has allowed the test of smaller amounts of material, faster testing procedures and more conclusive results. Finger ridge analysis is science and ...

Skeletal muscles are complex and highly specialized group of cells that are not isomorphic but can be categorized in a heterogeneous group with different qualities. This heterogeneity of the skeletal muscles is important because ensures different sets of functions that skeletal muscles perform in the human body. This heterogeneity also enables a significant ability of the human organism to adapt to different conditions in life (Pette and Staron 2000). In addition of this heterogeneity, skeletal muscles also posses the ability of plasticity. This means that muscle cells can evolve and adapt to different stimuli and change their characteristics (Tavi and Westerblad ...
