Ground nut Arachis hypogaea

We will mention one more piece of evidence for the existence of mRNA, which will enable us, at the same time, to become acquainted with a new technique. This is the evidence for mRNA in the cotyledons of the ground nut (Arachis hypogaea). During germination of such cotyledons a considerable increase in the activity of a whole series of enzymes which are necessary for the mobilization of reserve materials, occurs. It seemed likely that this increase in activity was due, at least in a large part, to the de novo synthQSis of enzymes. However, such de novo synthesis is impossible without mRNA. The technique with which we are concerned here is the hybridization of nucleic adds. If a DNA double helix is slowly heated, a sharp increase in the extinction of 260 m t over a par-... 

Fig. 146. Evidence for different mRNAs in cotyledons of the ground nut (Arachis hypogaea), which are phase-specific. (A) = control H - and Ci4-nucleic acids from cotyledons on the second day after germination. (B) = experiment H -nucleic acids from cotyledons on the second, C -nucleic acids from cotyledons on the fourteenth, day after germination. Considerable differences appear between the H - and C Aprofiles, particularly in the region of mRNA (right side of diagram) (modified from Key and Ingle 1966).
