Each of the following is true about Ras except: a. Ras activates a cascade of phosphorylation events within the cell.
b. Ras is monomeric. Ras is activated by Sos, a guanine nucleotide exchange factor.
c. Ras activity is inhibited by GTPase activating proteins (GAPs).
d. Ras binds steroid hormones.

c) Ras Binds steroid hormones

Explanation:

Ras which belongs to a protein family, which are used in the transmission of the signal within the animal cell. It should be noted that The protein in Ras is associated to Gpase.

The characteristics of Ras are:

✓ Ras is activated by Sos, a guanine nucleotide exchange factor

✓Ras activates a cascade of phosphorylation events within the cell

✓ Ras is monomeric

✓ Ras activity is inhibited by GTPase activating proteins.

Therefore, all the options are true about Ras except C.

the offspring would all be white. if the parents are both white flowers then they have the genotype rr, which when crossed results in an all white punnet square.
