1. If a virus has an outer shell
composed of the proteins
Neuraminidase 1 and Hemagglutinin
1, what disease will it cause upon
infecting a human being?
This disease is actually the reason why
you play the game Angry Birds on your
mobile phones.

Swine Flu
Hemagglutinin 1 is H1 and
Neuraminidase 1 is N1. Thus H1N1

2. Which taxonomic rank in
Whittaker’s Five Kingdom classification
is common to Drosophila
melanogaster and Anhinga
melanogaster?

Kingdom(Animalia)
Drosophila melanogaster Anhinga melanogaster

3. The bird is called the Eurasian Horned Eagle Owl It is 2’ to 2’6’’ in height
and has a wingspan of 5 to 6 feet. This massive owl is found in the
Nanmangalam Reserve Forest, Medavakkam, Chennai. The spotted deer is
found in the IIT campus and Guindy National Park. The spectacled cobra
can be found anywhere in Chennai.
There is something unique about their taxonomy. What is it?

Their genetic name and specific
name are the same.

4.
The term _____ derives from the expressed region and was
coined by American biochemist Walter Gilbert in 1978:
"The notion of the cistron… must be replaced by that of a
transcription unit containing regions which will be lost from the
mature messenger – which I suggest we call intragenic regions –
alternating with regions which will be expressed: _____.“
This definition was originally made for protein-coding transcripts
that are spliced before being translated. The term later came to
include sequences removed from rRNA and tRNA, and it also was
used later for RNA molecules originating from different parts of
the genome that are then ligated by trans-splicing
The gene for the synthesis of ‘titin’ or ‘connectin’(the largest
naturally found protein) has the largest number of ________
discovered in any single gene.

5.
In 2011, when narrating the first episode of an American television
series on the Discovery Channel, X declared the following:
“We are each free to believe what we want and it is my view that the
simplest explanation is there is no God. No one created the universe and
no one directs our fate. This leads me to a profound realization. There is
probably no heaven, and no afterlife either. We have this one life to
appreciate the grand design of the universe, and for that, I am extremely
grateful.”
X suffers from Lou Gehrig’s disease or ALS for which X devised a method of
a survival for the future. ALS arises out of lack of neuron communication
resulting in speaking difficulty and muscular dystrophy.
X recently featured in an episode of the TV series, The Big Bang Theory
which received great reviews among viewers.
Expand ALS.

6. X is a very important product that all of us
use. In the past, it was manufactured from
the raw materials given by organisms like
Hevea brasiliensis, Parthenium argentatum
and Ficus elastica. However, in the present, X
is manufactured from petroleum products.
Some examples of X manufactured from
petrochemicals are, polybutadiene,
polysiloxane and Vinyl Methyl Silicone.
ID X.

Round 2

1. X is a German-born Stanford
researcher. He will be awarded the
Nobel Prize in Physiology or
medicine this year along with
James Rothman and Randy
Schekman for his work on vesicle
trafficking. Identify X

2. X, Marshall Nirenberg and Robert
Holley received the Nobel Prize for
Physiology or Medicine in 1968 for
research that helped to show how
ribonucleotides control the cell’s
synthesis of proteins. X is the only
scientist of Indian origin to receive the
Nobel Prize for Physiology or
Medicine.
Identify X

3. Sir X, a Canadian received the
Nobel prize in1923 along with John
Macleod in Physiology or Medicine
for the discovery of a peptide
hormone produced by the beta-
cells of the pancreas, which
removes excess glucose from the
blood. Identify X.

4. X was awarded the first Nobel
Prize in Physiology or Medicine in
1901 for his work on serum
therapy and its application against
Diphtheria. Identify X

5. Harriet was a tortoise that Charles
Darwin took back home. It was his pet
until Darwin’s death after which it was
transported to Australia to be under
the care of the retired captain who
took Darwin to the Galápagos Islands.

changed hands many times. It was
under the care of X, that Harriet died.
X died about 2 months later in an
accident. Identify X.

2. What was the Cambrian Explosion?

The rapid diversification of the
complexity of organisms around
540 million years ago is called the
Cambrian Explosion.

3. On the left, we see a specimen of Titan Arum. On the
right, we see one of Rafflesia arnoldi. Clearly, the
former is bigger than the latter. Why is the Rafflesia
said to be the largest flower in the world?

Rafflesia is the largest single flower
