Mukesh is a boy with a daring attitude to drive a car. His family is engaged in making bangles. But his dream seems like a mirage. His family believes in ‘Karam theory.’

But Mukesh insists on being his own master. So he announces, I will be a motor mechanic. He repeats “I wants to be a motor mechanic.” He says he will go to a garage and learn. Though the garage is a long distance from his house yet he will walk to the garage.

He does not dream of flying a plane. He is content to dream of cars that he sees hurtling down the streets of his town. This shows that Mukesh has an attitude of doing something different from that of his family.

A commercial bank is a kind of financial institution which carries all the operations related to deposit and withdrawal of money for the general public, providing loans for investment, etc. These banks are profit-making institutions and do business only to make a profit.

The two primary characteristics of a commercial bank are lending and borrowing. The bank receives the deposits and gives money to various projects to earn interest (profit). The rate of interest that a bank offers to the depositors are known as the borrowing rate, while the rate at which banks lends the money is called the lending rate.

• An oxidation-reduction (redox) reaction is a type of chemical reaction that involves a transfer of electrons between two species. An oxidation-reduction reaction is any chemical reaction in which the oxidation number of a molecule, atom, or ion changes by gaining or losing an electron.
• The formation of hydrogen fluoride is an example of a redox reaction. We can break the reaction down to analyze the oxidation and reduction of reactants. The hydrogen is oxidized and loses two electrons, so each hydrogen becomes positive.

The Watson and Crick were the two scientists who proposed the double helical structure of DNA. They proposed that the double helical structure is held together by the hydrogen bonds which are present in between the nitrogenous bases present on the opposite strands of the DNA. The double stranded DNA is supported by the phosphate back bone.

The salient features of double helix structure of DNA are as follows:

1. There are two polynucleotide chains in a double stranded DNA.
2. The backbone is constituted by sugar phosphate.
3. The two strands possess anti-parallel polarity, means one chain has polarity 5’-3’ and the other has 3’-5’.
4. The two strands of DNA are joined together by hydrogen bonds between purines and pyrimidines. 
5. Adenine always pairs with Thymine by two hydrogen bonds and Guanine always pairs with Cytosine by three hydrogen bonds.
6. The two chains are coiled around each other where the pitch of the helix is 3.4 nm and distance between two base pairs is 3.4 A° (as in case of B-DNA)
7. The backbone of DNA double helix is formed by sugars and phosphates where bases are projecting inwards.

पूर्वी जर्मनी में शिक्षा मुफ्त थी लेकिन पश्चिमी जर्मनी में शिक्षा पर खर्च करना पड़ता था; इस कारण जर्मन छात्र शिक्षा के लिए पूर्वी हिस्से में जाते और नौकरी के लिए पश्चिमी जर्मनी लौट आते थे. द्वितीय विश्वयुद्ध के बाद जब जर्मनी का विभाजन हो गया, तो सैंकड़ों कारीगर, प्रोफेसर, डॉक्टर, इंजीनियर और व्यवसायी प्रतिदिन पूर्वी बर्लिन को छोड़कर पश्चिमी बर्लिन जाने लगे.

एक अनुमान के अनुसार 1954 से 1960 के दौरान 738 यूनिवर्सिटी प्रोफेसर,15, 885 अध्यापक, 4,600 डॉक्टर और 15,536 इंजीनियर और तकनीकी विशेषज्ञ पूर्व से पश्चिमी जर्मनी चले गए. कुल मिला कर यह संख्या 36,759 के लगभग है. लगभग 11 हजार छात्रों ने भी बेहतर भविष्य की तलाश में पूर्वी जर्मनी छोड़कर पश्चिमी जर्मनी चले गए.

जितने लोगों ने पश्चिमी जर्मनी के लिए पलायन किया था उनको अच्छी शिक्षा पूर्वी जर्मनी में मिली थी. इस प्रतिभा पलायन के कारण पश्चिमी जर्मनी को फायदा मिलने लगा और पूर्वी जर्मनी को नुकसान होने लगा.

यहाँ पर यह बताना भी जरूरी है कि जो लोग पूर्वी जर्मनी छोड़ना चाहते थे उनके लिए पश्चिमी बर्लिन में आकर वहां से विमान द्वारा पश्चिमी जर्मनी में जाना आसान था. इसके अलावा 1950 और 1960 के दशक के शीत युद्ध के दौरान पश्चिमी देश; बर्लिन को पूर्वी ब्लॉक की जासूसी के लिए भी इस्तेमाल करते थे.

अब ऐसे हालातों में पूर्वी जर्मनी को इस पलायन और जासूसी को रोकने के लिए कुछ न कुछ उपाय तो करने ही थे. इन्हीं सब वजहों से परेशान होकर पूर्वी जर्मनी की समाजवादी सरकार ने 12 और 13 अगस्त, 1961 की रात में पूर्वी और पश्चिमी बर्लिन की सीमा को बंद कर दिया था.

Demand Deposits also known as Current Account deposits refer to those deposits that provide the depositor the liberty to withdraw money at any point of time. That is, the account holder of the demand deposits can demand these deposits at any point of time as per their discretion and convenience. Such deposits do not offer any rate of interest.

 Coordination is the orderly arrangement of group efforts to provide unity of action in pursuit of common purpose. It involves unifying, integrating and harmonising the activities of different departments and individuals for the achievement of common goal.

Derry’s mother claimed to have heard many things about Mr. Lamb. So she did not allow her son to go there. She had been told and warned by the people. She told that so many stories were prevalent about Mr. Lamb. He was not a man to be believed. But the boy insisted and proceeded to Mr. Lamb’s house.
