I’m a student in master from the university of Strasbourg, France.
Yesterday, I’ve found a very interesting article, and I’ve some questions about it.
ScienceDaily (Apr. 17, 2009).
A new nucleotid is discovered, the 5-hydroxymethylcytosine.
I know that important modifications of nucleotids can introduce mutations in DNA during the replication if they are not corrected.
So, If the environnement modifie a nucleotide by methylation, hydroxylation, or other ; an epigenetic modification. Is it would be possible that a real modification is realized in the nucleic sequence, and finally, an heritable modification of the genomic sequence ?
Thank you for comments.
And escuse my poor english.
