Epigenetics I
-Recent discoveries in the field of epigenetics -- the study of heritable changes in gene function that occur without a change in the DNA sequence -- have blurred the neat picture of mutation and recombination, and are changing the way researchers think about heredity.
- Epigenetic mechanisms such as DNA methylation, histone acetylation, and RNA interference, and their effects in gene activation and inactivation, are increasingly understood to be more than "bit players" in phenotype transmission and development.
-Changes to DNA and its associated proteins can alter gene expression without altering the DNA sequence.
-Chemical modifications to the DNA or the histones alter the structure of the chromatin without changing the nucleotide sequence of the DNA. Such modifications are described as epigenetic.
