QUESTION 46

Which of the following statement(s) about tumor suppressor genes is/are TRUE?

		They keep cell proliferation in check by blocking the transition from one cell cycle phase to the other.
		As long as one copy of a tumor suppressor gene remains in its wild-type state, cell proliferation is safely kept in check.
		Their mutated variants in a homozygous state contribute to cancer.
		They are exemplified by the retinoblastoma protein.
		All of the above are ture.

		Endosymbiont hypothesis
		Genetic conflict hypothesis
		Trickle-down economics
		The Central Dogma of molecular biology
		Einsteins' Relativity Theory

QUESTION 50

Genes that show recombination between them 25% of the time

		Are not linked
		May be on different chromosomes
		Are linked on the same chromosome
		All of the above
		Only a and b are correct answers

Answer 1

ANSWER :

41. The biomolecular process, that makes a DNA strand by transcribing an RNA strand is called as reverse transcription.

42. If gene Q and P are linked, in the dihybrid testcross of cross of Qp/qP x qp/qp, the obtained recombinant genotypes would be Qp/qp and qP/qp.

43. Damage to DNA that occurs prior to DNA replication results in the arrest of normal cells at the G0 to G1 checkpoint.

44. Whether a female honey bee larva develops into a worker or a queen be is determined by the diet provided in larval stage. All the bee larvae that fed upon royal jelly exclusively, become hatched into queen bee later. Hence (4) is the correct answer choice.
