Awareness of genetic and other risk factors is important, because there are very effective means now available that could prevent most colon cancer morbidity and mortality. Cancer genetics was among the earliest clinical applications of the techniques of molecular biology. Advances in understanding the genetic basis of human diseases creates opportunities to make diagnostic and prognostic assessments based upon various types of analyses of variations in an individual’s DNA. A easy way to prevent colon cancer is early detection & colon cleaning to maintain colong health..
Molecular diagnosis involves the testing of DNA or RNA within a clinical context. The functions of nucleic acids and their encoded protein molecules are determined by the linear sequence of their monomers. Although the proteins they encode develop complex three dimensional functional conformations as linear peptide chains become enfolded into helical or pleated sheets or higher-order structures, the simple primary amino acid sequences determine the ultimate structure and function. In modern molecular biology research, it is now much easier to obtain long nucleic acid sequence information to deduce the sequence of proteins rather than determine them directly. The functional effects on the encoded protein of any mutations or sequence variations can then be discovered. Continue reading ‘Colon Cancer – Is it Genetic?’ »
