Difference Between DNA Sequence Mutations and Epigenetic Modifications
The key difference between DNA sequence mutations and epigenetic modifications is that during DNA sequence mutations, changes occur in the original DNA sequences while during epigenetic modifications, changes do not occur in the original DNA sequences.
The genome represents the overall genetic information of an organism in the form of precise DNA sequences or genes. A particular gene contains a particular genetic code to produce a specific protein. Hence, genes are expressed via two processes: transcription and translation.
