Functions of Taq DNA Polymerase in PCR Reaction

Single nucleotide polymorphism or SNP Marker is a single base change between DNA sequences in every 100 to 300 base pairs in heredity resulting change in amino acids leading to change in proteins or gene function in more than 1% in large population and variation in every 1000 base pairs refer to SNP marker So SNP that close to particular gene act as marker for that gene, Major allele frequency represent more than 50% while minor allele frequency represent less than 50%, SNP marker initiate by DNA extraction and sequence generation for preliminary data quality control to compare base sequences to discover SNP markers to generate map of genome containing all possible of SNP markers (Watch Related Video in #geneticteacher) #geneticteacher
