Read the passage carefully and choose the best answer to each question out of the four alternatives. Genetic variation is the cornerstone of evolution, without which there can be no natural selection, and so a low genetic diversity decreases the ability of a species to survive and reproduce, explains lead author Yoshan Moodley, Professor at the Department of Zoology, University of Venda in South Africa. Two centuries ago, the black rhinoceros – which roamed much of sub Saharan Africa – had 64 different genetic lineages; but today only 20 of these lineages remain, says the paper. The species is now restricted to five countries, South Africa, Namibia, Kenya, Zimbabwe and Tanzania. Genetically unique populations that once existed in Nigeria, Cameroon, Chad, Eritrea, Ethiopia, Somalia, Mozambique, Malawi and Angola have disappeared. The origins of the 'genetic erosion' coincided with colonial rule in Africa and the popularity of big game hunting. From the second half of the 20th century, however, poaching for horns has dramatically depleted their population and genetic diversity, especially in Kenya and Tanzania.
Sub Sharan Africa has lost how many black rhino genetic lineages in 200 years?

Choice the correct propositions:
1. Evidence of fingerprint expert is substantive evidence.
2. Evidence of fingerprint expert can be used only to corroborate some items of substantive evidence which are otherwise on record.
3. Evidence of fingerprint expert is not substantive evidence.
4. Evidence of fingerprint expert is admissible in all circumstances as expert evidence.
Steps of Recombinant DNA technology are given below.
1. Identification and isolation of the genetic material.
2. Fragmentation of DNA.
3. Obtaining the foreign gene product.
4. Downstream processing.
5. Ligation of DNA fragmentation into the vector.
6. Isolation of desired DNA fragments.
7. Amplification of gene of interest.
8. Transfer of Recombinant DNA into the host cell/organism.
The correct sequence of steps is
Each material circumstance appearing in evidence against the accused must be put to the accused specifically, distinctly and separately. In this context, the propositions are
1. Failure to put the material evidence to the accused always vitiates the trial
2. Failure to put the material evidence amounts to a serious irregularity which can not be cured and vitiates the trial, if it has prejudiced the accused.
3. Failure to put the material evidence is not considered to services & is curable if infact no failure of justice has occasioned to the accused.
Now which of the following is correct
Read the following paragraph and answer the following question. Hershey-Chase experiment broke the barriers of science and expanded the understanding of life. In this experiment, two sets of bacteriophages are used in which one contains radioactive sulphur in its protein coat (Set-I) and other contains radioactive phosphorus in its DNA (Set-II). These two sets were allowed reproduce in E.Coli culture and then centrifuged. Which among the following are correct Set-I and Set-II after centrifugation?
