Reading comprehension Questions answers

Question 1 Explanation: 
    • In the medieval ages, Manipur and Burmese kings often wrested the valley from each other until the British defeated the Burmese and signed the Treaty of Yandaboo in 1826.
    • But the valley was returned to Burma in the second treaty of 1834 and a boundary line between British India and Burma was drawn by Captain R.B. Pemberton.
    • The Pemberton Line had left out certain restive Kuki areas that were included in a rectified boundary in 1881 called Johnstone Line.
    • The boundary was redrawn again in 1896 to have 38 pillars and be known as Maxwell or Pemberton-Johnstone-Maxwell Line.

1 only
B
2 only
C
Both 1 and 2
D

Microbiology Questions answers

Question 3 Explanation: 
Statement 1 is correct -One pitfall of embryo gene-editing is that it is not as precise as we need it to be today. Studies have shown that the technology can result in unintended mutations, which in turn can cause cancers. Then there is the danger of mosaicism, in which some cells inherit the target mutation, while others don't.

Statement 2 is correct-

WHAT IS GENE EDITING

While scientists have long been able to find defective genes, fixing them has been so cumbersome that it's slowed development of genetic therapies. There are several gene editing methods, but a tool called CRISPR-Cas9 has sparked a boom in research as laboratories worldwide adopted it over the past five years because it's faster, cheaper, simple to use with minimal training and allows manipulation of multiple genes at the same time.

HOW IT WORKS

Pieces of RNA are engineered to be a guide that homes in on the targeted stretch of genetic material. The Cas9 is an enzyme that acts like molecular scissors to snip that spot. That allows scientists to delete, repair, or replace a particular gene
