A mutation that knocks out the GTPase activity of a G protein would have what effect on a cell?

#SCPH01 Biochemistry
  1. The concentration of available GTP would decrease.

  2. The number of G proteins in the cell would increase.

  3. The G protein would be inactivated by a G protein-coupled receptor/signal molecule complex.

  4. The G protein would always be active.

Imagine that height in corn plants is determined by three loci. The baseline height is 100 cm. Every + allele adds 10cm to the plant’s potential height, every – allele subtracts 10 cm from the plant’s potential height. The shortest possible plant and the tallest possible plant are mated to form an F1, what is the height of the F1?

Two varieties of maize averaging 50 and 20 inches in height, respectively, are crossed. The F1 progeny is quite uniform averaging 35 inches in height. Out Of the 16 F2 plants, the 5 are 35 inches. What is the probable number of independent segregating polygenes involved in this trait?
