A tablet. Another example would be the case of transdermal patches where the current trend is for a simple design, thinner and less conspicuous patches. If this article has seemed interesting to you and you want to update yourself on this matter, you can consult our training actions:clinical practice requires some indicators for the study of diseases. One of the indicators that has shown clinical utility is genetic markers . Specifically , epigenetic biomarkers have contributed to the screening of diseases, knowing their evolution and response to pharmacological treatments.
Thanks to the human genome project , progress has been made in the correct diagnosis of many diseases . In order to contextualize the topic, it is necessary to explain concepts related to the discipline of genetics that are specified below. Key concepts genetic variation in the population occurs mostly in genetic polymorphism . The polymorphism corresponds to a place in the deoxyribonucleic acid (dna) sequence where a variation exists, and the less common e commerce photo editing service variant is present in at least 1% of the population analyzed. Thus, genetic polymorphism is responsible for the great genetic variability that exists between individuals of the same species. In order to estimate this variability, genetic markers are used.
A genetic marker is a segment of dna with a physical location on a known chromosome called a polymorphic locus. In other words, a genetic marker is any character or trait that allows its inheritance to be followed through successive generations. Broadly speaking, these genetic markers are associated with specific disease phenotypes and are useful as a diagnostic tool . In turn, epigenetics is defined as the study of the mechanisms that regulate gene expression without modifying the dna sequence. In this sense, epigenetics
