"What is DNA "?
"KNOW ABOUT D.N.A"
DNA
DNA repair refers to a collection of processes by which a cell identifies and corrects damage to the DNA molecules that encode its genome. In human cells, both normal metabolic activities and environmental factors such as UV light can cause DNA damage, resulting in as many as 1 million individual molecular lesions per cell per day. Many of these lesions cause structural damage to the DNA molecule and can alter or eliminate the cell's ability to transcribe the gene that the affected DNA encodes. Other lesions induce potentially harmful mutations in the cell's genome, which affect the survival of its daughter cells after it undergoes mitosis. Consequently, the DNA repair process must be constantly active so it can respond rapidly to any damage in the DNA structure.
The rate of DNA repair is dependent on many factors, including the cell type, the age of the cell, and the extracellular environment. A cell that has accumulated a large amount of DNA damage, or one that no longer effectively repairs damage incurred by its DNA, can enter one of three possible states: an irreversible state of dormancy, known as senescence; cell suicide, also known as apoptosis or programmed cell death; or unregulated cell division, which can lead to the formation of a tumor that is cancerous.

"Man Is Architect Of His Own Future"
Most of us say that God, or destiny or whatever superior force may exist in this universe are that which make our future, that guide us throughout our futile existence.
I don't claim there isn't a force which guides us, which takes care of us, but the main element that helps us build up our future is our way of being. Our personality, our character, our way of perceiving reality and everything that surrounds us are the elements which may bring us to the top, or on the contrary, make us miserable.
It's simply your own choice if you don't want to study, to go to college, to have a career. It really doesn't matter if your parents threaten you, they punish you, scold you all the time. If you are stubborn and you think you know it all then all these are useless.
You are the one who decides what job to have, in what city or what country. It's your choice and your responsibility. The moment you get hurt or something goes wrong, you blame yourself, and you start everything from the very beginning.
You consider that you can't find your place in your own country, so you risk the comfortable but modest life you have living with your parents and you go abroad. Maybe there will be moments when you can't stand anymore the loneliness, the strangers around you, or your job. But you remember nobody made you take that decision, so you take a deep breath, and you go on, as it's very difficult to find a guilty person when you know it well you the only one to be blamed.
If you fall in love with a man from the very first moment you set your eyes on him and you don't want to meet somebody else, to see how they are it's your wish. If you get married and the marriage ends in a year's time, you can't blame the rest as they all had told you to be careful and never to take hasty decisions.
You play the lottery each day and there are two options: either you hit the jack pot and your life changes radically or you lose and you have to start it from the very beginning. On the contrary, it's well known that if you don't risk you can't win so the best solution is always to think over and over again your decisions, to see what they could represent in your future and only afterwards to make up your mind.
You are the only architech of your future. The rest are only workers who help you create your own dream.

"MATHS MODEL PAPER"
"SOLVE THE FOLLOWING QUESTION"
Q1)solve for x and y
47x + 31y = 63
31x + 47y = 15 ans. x=2,y=-1
Q2) Aman sold a chair and table together for Rs.850 at a loss of 10% on the table and a gain on chair of 10%. on selling together of Rs. 950,he would made a gain of 10% on the table and 10% loss on the chair. find c.p. of each?
Q3)A's says to B "I am 5 times as old as you were;when i was as old as you are."The sum of their present ages is 64. find their present ages?
Q4)A men when asked how many hens and buffalos he has, he replied that his animals have 120 eyes and 180 legs. find number of hens and buffalos?
Q5)the larger angle of triangle is equal tothe sum of other two angles. the smallest angle is 1/4 of the larger angle. find the angles?

"MODERN PANCHATANTRA STORIES"
Modern Panchtantra Story [ IT HUMOR ]
Once upon a time, there was a software engineer who used to develop
programs on his Pentium machine, sitting under a tree on the banks of a
river. He used to earn his bread by selling those programs in the Sunday
market.
One day, while he was working, his machine tumbled off the table and fell
in the river. Encouraged by the Panchatantra story of his childhood ( the
woodcutter and the axe )
He started praying to the River Goddess. The River Goddess wanted to test
him and so appeared only after one month of rigorous prayers. The engineer
told her that he had lost his computer in the river.
As usual, the Goddess wanted to test his honesty. She showed him a match
box and asked, "Is this your computer ?
" Disappointed by the Goddess' lack of computer awareness, the engineer
replied, " No."
She next showed him a pocket-sized calculator and asked if that was his.
Annoyed, the engineer said "No, not at all !!"
Finally, she came up with his own Pentium machine and asked if it was his.
The engineer, left with no option, sighed and said "Yes."
The River Goddess was happy with his honesty. She was about to give him all
three items, but before she could make the offer, the engineer asked her,
"Don't you know that you're supposed to show me some better computers
before bringing up my own ?"
The River Goddess, angered at this, replied, "I know that, you stupid
donkey! The first two things I showed you were the Trillennium and the
Billennium, the latest computers from IBM !". So saying, she disappeared
with the Pentium !!
Moral: If you're not up-to-date with technology trends, it's better to keep
your mouth shut and let people think you're a genius than to open your
mouth and remove all doubt.
