Hello to everyone !
"Epigenetics is the study of molecular processes that influence the flow of information between a constant DNA sequence and variable gene expression patterns. This includes investigation of nuclear organization, DNA methylation, histone modification and RNA transcription. Epigenetic processes can result in intergenerational (heritable) effects as well as clonal propagation of cell identity without any mutational change in DNA sequence".....Nature
The behavior of a person's genes doesn't just depend on the genes' DNA sequence - it's also affected by so-called epigenetic factors. Changes in these factors can play a critical role in disease.
In this video, I have tried to explain 2 very commonly misunderstood phenomenon Angelman syndrome and Praderwilli syndrome. I am sure this will make the concepts very clear.
