The origin of life on earth can be understood only against the background of origin of universe especially earth. Most scientists believe chemical evolution, i.e., formation of biomolecules preceded the appearance of the first cellular forms of life.

Nucleic acids are long polymers of nucleotides. While DNA stores genetic information, RNA mostly helps in transfer and expression of information. Though DNA and RNA both function as genetic material, but DNA being chemically and structurally more stable is a better genetic material. However, RNA is the first to evolve and DNA was derived from RNA.

Genetics is a branch of biology which deals with principles of inheritance and its practices. Progeny resembling the parents in morphological and physiological features has attracted the attention of many biologists.

She was one of those pretty, young ladies, born as if through an error of destiny, into a family of clerks. She had no dowry, no hopes, no means of becoming known, loved, and married by a man either rich or distinguished; and she allowed herself to marry a petty clerk in the office of the Board of Education. She was simple, but she was unhappy.

At the age of twenty-two, a former ‘scout of the year’ excited the scientific world with a new theory on how cells work. Richard H. Ebright and his college room-mate explained the theory in an article in the Proceedings of the National Academy of Science.

THE two boys started in surprise at the fresh muddy imprints of a pair of bare feet. What was a barefooted man doing on the steps of a house, in the middle of London? And where was the man?

Everyone thought that Horace Danby was a good, honest citizen. He was about fifty years old and unmarried, and he lived with a housekeeper who worried over his health. In fact, he was usually very well and happy except for attacks of hay fever in summer. He made locks and was successful enough at his business to have two helpers. Yes, Horace Danby was good and respectable — but not completely honest.

Ausable did not fit any description of a secret agent Fowler had ever read. Following him down the musty corridor of the gloomy French hotel where Ausable had a room, Fowler felt let down. It was a small room, on the sixth and top floor, and scarcely a setting for a romantic adventure.

I WAS still a thief when I met Anil. And though only 15, I was an experienced and fairly successful hand.

I was really worried about Tricki this time. I had pulled up my car when I saw him in the street with his mistress and I was shocked at his appearance. He had become hugely fat, like a bloated sausage with a leg at each corner. His eyes, bloodshot and rheumy, stared straight ahead and his tongue lolled from his jaws.

In a world where women’s potential in science, technology, engineering, and mathematics (STEM) is being recognised beyond doubt, India has seen its share of trailblazers who paved the way.

With this round glass
I can make Magic talk —
A myriad shells show
In a scrap of chalk;

To the best of my knowledge, there’s never been a regulation that forbids one to keep pets in a space station. No one ever thought it was necessary — and even had such a rule existed, I am quite certain that Sven Olsen would have ignored it.

“I hope it rains at least today,” Velu thought, as he opened his eyes.

Men’s Voices:

Towards the end of the rainy season new leaves appeared on the tree. Then a woman cutting grass scrambled down the hillside, her scythe swishing through the heavy monsoon foliage. She did not try to avoid the tree: one sweep, and the cherry tree was cut in two.

One day, when Rakesh was six, he walked home from the Mussoorie bazaar eating cherries. They were a little sweet, a little sour; small, bright red cherries, which had come all the way from the Kashmir Valley.

India is home to some of the most mystifying natural phenomena that surprise and spark our imagination.

“Go and gather wild beans, Gopi,
Go and fetch some rice.
Go and pluck the mangoes
And bring home something nice.”

Encyclopedia Brown is a young boy who lives in Idaville, USA. His father is the Chief of Police. In spite of being so young he often helps his father solve mysteries that even the police find difficult to solve.

The woman was old and ragged and grey
And bent with the chill of the Winter’s day.

This is a tribute to the valiant Major Somnath Sharma, India’s first recipient of the Param Vir Chakra, whose name is etched in the annals of history. His bravery and sacrifice stand as a beacon of inspiration for generations.

Until the middle of the twentieth century, production was largely organised within countries. What crossed the boundaries of these countries were raw material, food stuff and finished products.

On one side are the depositors who keep their money in the banks and on the other side are the borrowers who take loans from these banks.

My next-door neighbour, Mrs. Jones,
has got a garden full of stones:
A crazy path, a lily pond,
a rockery and, just beyond
A sundial with a strange device,
which Mrs. Jones thinks rather nice.

When we produce a good by exploiting natural resources, it is an activity of the primary sector. Since most of the natural products we get are from agriculture, dairy, fishing, forestry, this sector is also called agriculture and related sector.

Different persons can have different developmental goals. What may be development for one may not be development for the other. It may even be destructive for the other.

The Vijayanagara Empire was renowned for its glory, wealth, and cultural achievements. Among its many illustrious rulers, King Krishnadeva Raya (ruled 1509–29 CE) stood out as a wise and powerful monarch.

The railroad track is miles away,
And the day is loud with voices speaking,
Yet there isn’t a train goes by all day
But I hear its whistle shrieking.

It was almost noon, and the jungle was very still, very silent. Heat waves shimmered along the railway embankment where it cut a path through the tall evergreen trees. The railway lines were two straight black serpents disappearing into the tunnel in the hillside.

Day by day I float my paper boats one by one down
the running stream.

“Who put that water bag here?” roared my father from the front doorstep. “Your burglar alarm,” I hissed to my brother Anand, who was getting ready to disappear from the house. Ma rushed in to see what the racket was all about and found Papa standing there, sopping wet and scowling.

This is a humorous play in which a mother advises her daughter to say the right thing at the right time. However, when guests arrive, the daughter hilariously forgets her mother’s guidance.

One day a funny kind of man
Came walking down this street
He wore a shoe upon his head
And hats upon his feet.

Doctor Dolittle was sitting in his kitchen talking with the Cat’s-food-Man who had come to see him with a stomach-ache.

I, who cannot see, find hundreds of things to interest me through mere touch. I feel the delicate symmetry of a leaf. I pass my hands lovingly about the smooth skin of a silver birch, or the rough, shaggy bark of a pine.

King Bruce of Scotland flung himself down
In a lonely mood to think;
‘Tis true he was monarch, and wore a crown,
But his heart was beginning to sink.

A big bright tear splashed down her nose. And another. A kingfisher swept down, its wings an arrow of blue in the sunlight. And a green lizard slithered down to the river’s edge to bask in the sun.

When you enter a tiny room in Moti Vavdi village, Bhavnagar, Gujarat, you will see lots of bright colours. There are many lovely things like cushions, bedcovers, pillows, and more, with beautiful designs.

Up in the air
See the kites fly,
Like coloured birds
In the wind-whipped sky.

Bharat has been known worldwide as a land of wise and heroic individuals. Its rich and diverse culture has attracted numerous travellers since ancient times. The people here live in unison, presenting to the world unity in diversity.

Yoga is a physical, mental, and spiritual practice that originated in ancient India. The word ‘Yoga’ comes from the Sanskrit root ‘yuj’, which means ‘to join’ or ‘to unite’.

Evenings, we play ball next to the creek in our neighbour’s field.

Prabhat always wanted to win. His parents, teachers, and friends said that he did not know how to accept defeat. The fact was that he could not bear losing, not even at marbles.
