Active sites of the enzyme is that point where substrate molecule bind for the chemical reaction. It is generally found on the surface of enzyme and in some enzyme it is a “Pit” like structure
The active site is a three-dimensional cleft formed by groups that come from different parts of the amino acid sequence
The active site takes up a relatively small part of the total volume of an enzyme
Active sites are clefts or crevices
Substrates are bound to enzymes by multiple weak attractions.
The specificity of binding depends on the precisely defined arrangement of atoms in an active site.
An enzyme is a substance that acts as a catalyst in living organisms, regulating the rate at which chemical reactions proceed without itself being altered in the process. The biological processes that occur within all living organisms are chemical reactions, and most are regulated by enzymes

The process of transcription is the first stage of gene expression resulting in the production of a primary RNA transcript from the DNA of a particular gene.
This step of gene expression which is followed by a number of post-transcriptional processes such as RNA splicing and translation.
These lead ultimately to the production of a functional protein and this process is highly regulated.
Both basal transcription and its regulation are dependent upon specific protein factors known as transcription factors.
These highly specific protein bind to the specific regulatory gene of DNA sequence and control the transcription process and regulate it.
For example- enzyme RNA polymerase catalyzes the chemical reaction that synthesize RNA, using the DNA gene as a template, the transcription factor control when, where, and how efficiency RNA polymerase function.
Play an important role in the normal development and routine of cellular function.
Novel opportunities for computational biology and sociology inavinash tiwari
Current drug discovery is impossible without sophisticated modeling and computation. In this
review we outline previous advances in computational biology and, by tracing the steps involved
in pharmaceutical development, explore a range of novel, high-value opportunities for
computational innovation in modeling the biological process of disease and the social process of
drug discovery. These opportunities include text mining for new drug leads, modeling molecular
pathways and predicting the efficacy of drug cocktails, analyzing genetic overlap between diseases
and predicting alternative drug use. Computation can also be used to model research teams and
innovative regions and to estimate the value of academy–industry links for scientific and human
benefit. Attention to these opportunities could promise punctuated advance and will complement
the well-established computational work on which drug discovery currently relies.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
