A DC generator is an electrical machine whose main function is to convert mechanical energy into electricity. When conductor slashes magnetic flux, an emf will be generated based on the electromagnetic induction principle of Faraday’s Laws. This electromotive force can cause a flow of current when the conductor circuit is closed.
A DC generator can also be used as a DC motor without changing its construction. Therefore, a DC motor, otherwise a DC generator can be generally called a DC machine. Below, we have mentioned the essential parts of a DC Generator.

- Translation refers to the process of polymerization of amino acids to form a polypeptide.
- The order and sequence of amino acids are defined by the sequence of bases in the mRNA and the amino acids are joined by a bond which is known as a peptide bond.
- Formation of a peptide bond requires energy and thus amino acids are activated in the presence of ATP and linked to their cognate tRNA by the process of charging of tRNA or aminoacylation of tRNA.
- If charged tRNAs are brought close enough, a peptide bond forms which is enhanced by the presence of a catalyst such as ribosome.
- Ribosome in its inactive state exists as two subunits; a large subunit and a small subunit.
- There are two sites in the large subunit, for subsequent amino acids to bind to and thus become close enough to each other for the formation of a
peptide bond.
- A translational unit in mRNA is the sequence of RNA that is flanked by the start codon (AUG) and the stop codon and codes for a polypeptide.
- An mRNA also has some additional sequences that are not translated and are referred as untranslated regions (UTR).
- The UTRs are present at both 5'-end (before start codon) and at 3'-end (after stop codon) which are required for efficient translation process.
- After activation of amino acids, translation starts with its three steps-
- Initiation
- Elongation
- Termination

जनहित याचिका एक ऐसा माध्यम है, जिसमें मुकदमेबाजी या कानूनी कार्यवाही के द्वारा अल्पसंख्यक या वंचित समूह या व्यक्तियों से जुड़े सार्वजनिक मुद्दों को उठाया जाता है. सरल शब्दों में, जनहित याचिका (PIL) न्यायिक सक्रियता का नतीजा है, जिसके माध्यम से एक व्यक्ति या एक गैर-सरकारी संगठन या नागरिक समूह, अदालत में ऐसे मुद्दों पर न्याय की मांग कर सकता है जिसमें एक बड़ा सार्वजनिक हित जुड़ा होता है.
वास्तव में जनहित याचिका, कानूनी तरीके से सामाजिक परिवर्तन को प्रभावी बनाने का एक तरीका है. इसका उद्देश्य सामान्य लोगों को अधिक से अधिक कानूनी सहायता प्राप्त करने के लिए न्यायपालिका तक पहुंच प्रदान करना है.

Process of transcription
In prokaryotes
Transcription takes place in three steps
- Initiation
- RNA polymerase binds to promoter and initiates transcription.
- Initiation factor or sigma (σ) recognizes the promoter of the DNA.
- Elongation
- RNA polymerase facilitates opening of the helix and continues elongation.
- RNA polymerase uses nucleoside triphosphates as substrate and polymerizes in a template depended fashion following the rule of complementarity.
- Only a short stretch of RNA remains bound to the enzyme.
- Termination
- Once the polymerases reaches the terminator region RNA polymerase binds with the termination-factor (ρ) to terminate transcription.
- The nascent RNA falls off with the RNA polymerase which results in termination of transcription.
- The transcription and translation can be coupled in bacteria as the mRNA does not require any processing to become active, and also transcription and translation take place in the same compartment
In eukaryotes
- There are two additional complexities in eukaryotes.
- The first complexity is that there are at least three RNA polymerases in the nucleus.
- The RNA polymerase I transcribes rRNAs (28S, 18S, and 5.8S)
- The RNA polymerase III is responsible for transcription of tRNA, 5srRNA, and snRNAs (small nuclear RNAs).
- The RNA polymerase II transcribes precursor of mRNA, the heterogeneous nuclear RNA (hnRNA).
- The second complexity is that the primary transcripts contain both the exons and the introns and are non-functional.
- Primary transcripts are subjected to a process called splicing where the introns are removed and exons are joined in a defined order.
- hnRNA undergo two additional processing called as capping and tailing.
- In capping an unusual nucleotide (methyl guanosine triphosphate) is added to the 5'-end of hnRNA.
- In tailing, adenylate residues (200-300) are added at 3'-end in a template independent manner and the fully processed hnRNA is called mRNA
- mRNA is transported out of the nucleus for translation.
Significance of complexities
- The split-gene arrangements represent probably an ancient feature of the genome.
- The presence of introns is reminiscent of antiquity, and the process of splicing represents the dominance of RNA-world.

Today, we suffer from a “population explosion.” This means that the world’s population has been booming rapidly, rising to unwanted numbers. Looking back at history, the world’s population in 3,000 BC was an estimated 200 million, but now the world’s population has gone up to 7 billion. As we reach an environmental tipping point, we must find solutions for this rapid growth.
Four Possible Effects of Overpopulation:-
1. Food Shortage
2. Increase in Malignant Diseases
3. Higher Prices
4. Higher Levels of Pollution

Following are the main teachings of the Mahavira:
People, who wish to know the truth, must leave their home.
The truth seeker must follow the rules of ahimsa. The rule of ahimsa means not hurting or killing any living being. Life is dear to all living being

The main teachings of the Buddha were:
The Buddha taught that life is full of suffering and unhappiness. This is caused because we have cravings and desires (which cannot be fulfilled).
Sometimes, even if we get what we desire, we are not satisfied (permanently) and want (or desire) even more and more (or other things). The Buddha described this as thirst or tanha.
The Buddha taught that thirst or tanha or constant craving could be removed by following moderation in everything.
He also taught people to be kind and to respect the fives of others, including animals.
The Buddha believed that the result of our actions (called Karma), whether good or bad, affect us both in this life and the next.
He also encouraged, people to think for themselves rather than to follow simply what he (the Buddha) said.
The Buddha taught in Prakrit, which was the language of the ordinary people, so that everybody could understand his message.
