Q

Graphene

A

It is a single layer (Monolayer) of carbon atoms, tightly bound in a hexagonal honeycomb lattice.

Graphene is being used to boost not only the capacity and charge rate of batteries but also the longevity.

With Graphene tin oxide as an anode in lithium-ion batteries, batteries last much longer.

No reduction in storage capacity between charges.

Q

Gold Nano Particles

A

They are being clinically investigated as potential treatments for cancer and other diseases.

It illustrates unique properties that occur at the nanoscale. Nanoscale gold can appear red or purple depending on the size of the particle. Gold nanoparticles interact differently with light compared to larger-scale gold particles due to quantum effects.

Q

Gene Doping

A

In gene doping, the genetic material is delivered into cells and tissues using carriers that can be viral or non-viral

World Anti-Doping Agency is a foundation initiated by the International Olympic Committee based in Canada to promote, coordinate and monitor the fight against drugs in sports.

17
Q

Mitochondrial spindle transfer

A

Mitochondria is replaced in the ovum before fertilisation. Most popularly used method.

18
Q

Pronuclear transfer

A

Mitochondria is replaced in the zygote after fertilisation. This is a less popular form of method due to high risk

19
Q

First country in the world to allow genetic changes in Embryos

A

Britain

In 2016, the worlds first three parent baby was born where a healthy mitochondria was obtained from another female.

ANY defect in mitochondrial DNA will cause diseases related to the eyes, brain, muscles, heart and liver. It may cause a serious medical problem known as Charge Syndrome or Leigh Syndrome

20
Q

Rashtriya Gokul Mission

A

Launched in 2014 to develop and conserve the indigenous bovine breeds for improving milk production and productivity in a scientific manner and making dairying more remunerative to the rural farmers of the country.

National Gopal Ratna awards are conferred under the Rashtriya Gokul Mission

21
Q

ISRO currently uses RH200, RH300, RH300 Mk-II, RH560 Mk-II and RH560 Mk-III rockets which are launched from the Thumba Equatorial Rocket Launching (TERLS) in Thumba and the Satish Dhawan Space Center in Sriharikota.

25
Q

Largest fruit producing bamboo

A

Muli in North East India. It is native to the Northeast.

26
Q

Mautam

A

It is a cyclic ecological phenomenon that occurs every 48-50 years in the northeaster Indian states of Tripura, Mizoram and Manipur, as well as in many places of Assam which are 30% covered by wild bamboo forests.

It begins with a rat population boom, which in turn creates a widespread famine in those areas.

During mautam, Melocanna baccifera, a species of bamboo, flowers at one time across a wide area

This event is followed invariably by a plague of black rats in what is called a rat flood.

27
Q

White Goods

A

Large home appliances such as stoves, refrigerators, freezers, washing machines, tumble driers, dishwashers and air conditioners.

They are large electrical goods/

Recently, Production Linked incentive scheme was rolled out for white goods.
