For the short-term storage (up to one month), it is fine to keep DNA
(dissolved in TE buffer, pH 8.0) at 4 deg, centigrade. However, for the
long-term storage (say, more than six months), it is better to keep DNA
(dissolved in TE buffer, pH 8.0) at -70 (or -80) deg centigrade. In between,
it is all right to keep DNA at -20 deg centigrade.

organisms contain genes in them and that the future organism is written in
this 'somehow'. And 'somehow' is what we have to explain. We have to say not
'somehow', but 'how'. " --- Sydney Brenner
