In a breading experiment, plants with red flowers were crossed. They produced 123 plants with red flowers and 41 with white flowers.
(a) Identify the recessive characteristic.
(b) What was the genotype of the parent plant?

One class of aminoacyl tRNA synthetases possesses "proofreading" abilities. An experiment was carried out where a cysteine attached to tRNA was chemically modified to an alanine.
Beadle and Tatum discovered several classes of Neurospora mutantsthat were able to grow on minimal medium with arginine added. Class I mutants were also ableto grow on medium (no arginine) supplemented with either ornithine or citrulline, whereasc..
