Answer:
Option-A
Explanation:
RhoA is a protein which belongs to the Rho GTPase family proteins and related Ras superfamily. The Rho A protein is involved in the cell division before the cytokinesis as they are involved in the formation of cytokinesis structures like the actin-myosin rings and the contractile ring formation.
In the given question, if the drug inhibits the activity of RhoA, therefore, cytokinesis will be affected and the cell will complete all the stages of Mitosis except cytokinesis. The cells will be mostly observed in the telophase as cytokinesis will take place after that.
Thus, Option-A is correct.
Answer:
The hierarchy of selection. We most typically think of natural selection working at the level of the individual, favoring those better at leaving behind more individual descendants. However, with a little imagination, we can see how natural selection might work at other levels of biological organization as well.
Explanation:
Hitchhicker's thumb is a condition in which a person is able to bend his thumb backwards. This trait can be seen in many people but the condition is recessive, which means a person needs two alleles for hitchhiker's thumb to have this particular characteristics. The gene for straight thumb is commonly indicated by T while that for hitch hicker's thumb is indicated by t.
Let's see what will happen if a person heterozygous for hitchhiker's thumb marries a woman who is also heterozygous for hitchhiker's thumb.
P1: Tt X Tt
Gametes: t T : t T
Offsping : TT : Tt : tT : tt
TT : 25 % : Straight thumb
Tt + tT : 50% : Straight thumb
tt : 25% : Hitch hicker's thumb
Therefore, there are 25 % chances that their offspring will have Hitch hicker's thumb and 75 % chances that they will have straight thumb.
