A mutagen is a chemical that can induce alterations in the DNA. Mutations occurring in germ cells are inheritable and may lead to genetic diseases. If mutations take place in somatic cells, carcinogenesis may be initiated. [Pg.316]

Enhancement of the catalytic activity of the wheat germ, cell-free, protein synthesis system using a fortified translation extract... [Pg.169]

A wheat germ, cell-free, translation extract was fractionated into three concentrated parts using ammonium sulfate the 0 - 40 % saturated fraction, the 40 - 60 % saturated fraction, and the ribosome fraction. These fractions were tested for their ability to enhance the translational activity of the wheat germ, cell-free extract for dihydrofolate reductase. The fortified cell-free system supplemented with the 0 - 40 % ammonium sulfate fraction enhanced the efficiency of protein synthesis by 50 %. [Pg.169]

Control normal wheat germ cell-free system, (I) 0 - 40 % ammonium sulfate fraction 3 pi, 40 - 60 % ammonium sulfate fraction 4 pi, and ribosome 3 pi were added to 25 pi reaction mixture, (II) 0-40 % ammonium sulfate fraction 4 pi, 40 - 60 % ammonium sulfate fraction 4 pi, and ribosome 1.5 pi were added to 25 pi reaction mixture.
