Question

Use the following information to answers the questions below. Two-true-breading stocks of per plans are crossed. One percent has rod, axial flowers and the other has white, flowers all F_1 individuals have red, axial flowers. The games for flower color and location independently. If 2,000 F_2 offspring resulted from the chose, how many of them would you expect to have red, terminal flowers? A) 190 B) 65 C) 750 D) 565 E) 250 A series of enzymes catalyze the reaction X c- Y - Z - A. Product A binds to the enzyme that converts X to Y at remote from its active site. This binding the activity of the enzyme. What is substance X? A) a substrate B) the product C) a coenzyme D) an intermediate E) an allosteric inhibitor Use the following information to answer the questions below. The letter circle in Figure 12.1 shows a diploid nucleus with four chromosomes. There are two pairs chromosomes, one long and the other short. One haloed set is symbolized as black and the other hap chromosomes in the unlettered circle have not yet replicated. Choose the correct chromosomal.

Explanation / Answer

27 -given that Red flower is the dominant and axial flower is a recessive character. If we look at the F2 generation of dihybrid crosses we will find that there will four types of population

RED and axial flower: Red and terminal flower: White and Axial flower: White and terminal flower in 9:3:3: 1 ratio

So from the given population out of 1000 progeny Red and terminal flower population will be 190.

So the answer is option A - 190.

28-

Allosteric inhibitors are the inhibitor which binds to the enzyme such that they change the conformation of the enzyme due to which enzyme loses its activity substantially.

So the answer is allosteric inhibitor which is option E.
