Description: It was once believed that women are born with all the eggs they’ll ever have. In a study published in Nature Medicine, Jonathan Tilly, professor of obstetrics, gynecology, and reproductive biology found that stem cells taken from a women’s ovaries can be used to create new eggs or oocytes, a potentially groundbreaking discovery for fertility treatments. Using donated frozen ovaries from doctors in Japan who treat women seeking gender reassignment, Tilly’s team isolated egg-producing stem cells in human ovaries using new cell-sorting techniques to coax them into developing oocytes. Building on research by Chinese scientists, they then fished out a protein believed to sit on the surface of only those stem cells and tracked them by inserting a gene into the cells which caused them to glow green. If the cells produced eggs, the eggs would also glow green. The cells were then injected into biopsied human ovarian tissue that was then grafted beneath the skin of mice. Within 7 to 14 days, the graft had produced a budding of oocytes, with some of the eggs glowing with the fluorescent tag, proving that they came from the stem cells. But others did not, which suggested they were already present in the human tissue before the injection. “The discovery opens the door for development of unprecedented technologies to overcome infertility in women. If the process can be guided correctly, there is a chance that sometime in the future, we might get to the point of actually having an unlimited source of human eggs, which would rewrite human-assisted reproduction”, Tilly said in a press release.


1. According to the passage, the reason that Tilly’s team inserted a gene into the stem cells was to







Description: Nowadays, almost everyone is equipped with a mobile phone, mainly because mobile phones offer a fast and convenient way of communication.

Description: The company 'Dreams' has been producing most of its products in Costa .The government of Costa has passed a new ruling that states that all workers including that of 'Dreams' will have to be provided with double the wages .Hence the cost of products of company 'Dreams' will increase. 


6. The conclusion above assumes that...







Description: A recent report declaim that 80 percent of the people in this country now report that they know someone who is divorced. But the average divorce rate in this country is 4 percent, which means one out of 25 people should be divorced. So at any specific time if a person knows approximately 50 persons, two or more will very likely be divorced.


7. The conclusion drawn above depends on which of the following assumptions?








8. The number of pilgrims who visit the annual Ladakh festival increase every year.
