PPT-Epigenetic Marks

Any stable modification of DNA DNA modifications almost all methylation on C 5methylcytosine mostly at CpG dinucleotides Some other methylation derivatives Histone modifications by adding groups. Lamarck Revisited. Lamarck was incorrect in thinking that the inheritance of acquired characters is the main mechanism of evolution. However, we now know that the inheritance of acquired characters .
