Interference 103,781
A. I started in November 1985. I took the shorter
RNA’s that we had purified from the transformed tobacco
plants and I set about doing a set of experiments to try
and identify exactly what sequences were at the end of the
short RNA’s. And those kinds of experiments are called
nucleus [sic, nuclease?] protection.
Dr. Murray proceeded to describe the kind of experiments
which were performed and the periods of time over which they were
performed. In example (AR 4156, p. 461, l. 22, - p. 462, l. 4):
Q. When did you start working on those nuclease
protection assay experiments?
A. I started working on these in November 1985.
Q. And how long did they continue?
A. Well, I worked on them intermittently, doing other
experiments along the way, through August of 1987. And I
still continued to try and complete some experiments after
August 1987 until January 1988.
For other examples, see the following testimony (AR 4156,
p. 462, l. 7, - p. 463, l. 3)(emphasis added):
Q. What else did you do?
A. Well, I continued to do some Northern experiments,
because I was looking for RNA to do the nuclease protection
experiments with. And the nuclease protection experiments
were designed to look at the short RNA’s and they weren’t
always present in the transformed plants.
And I continued to work on a new technique that I and
another scientist at Agrigenetics were developing so I
could do more rapid analysis of the Bt genes in a plant
cell. And the technique is called electroporation.
