This document discusses PCR (polymerase chain reaction), which is a technique that takes a specific sequence of DNA and amplifies it for further testing. It works by denaturing double-stranded DNA, annealing primers to the single strands, and using DNA polymerase to extend the primers, replicating the DNA. This process is repeated in cycles to exponentially amplify the target DNA sequence. The key components needed are DNA template, primers, thermostable DNA polymerase like Taq, and a thermal cycler machine to change temperatures for denaturation, annealing and extension steps. PCR has applications in molecular identification, genetic engineering, and DNA sequencing.

POLYMERASE CHAIN REACTION ( PCR)
PCR (polymerase chain reaction) is a technique used to amplify a specific DNA sequence. It was invented in 1983 by Kary Mullis, who received the Nobel Prize for it. PCR uses DNA polymerase to exponentially replicate a target DNA sequence by cycling between high and low temperatures. It requires a DNA template, primers that define the target sequence, DNA building blocks (dNTPs), a thermostable DNA polymerase, magnesium ions, and a buffer solution. During cycling, the DNA is denatured, the primers anneal, and the polymerase extends the DNA. This process doubles the DNA after each cycle, allowing millions of copies to be produced rapidly for analysis using gel electrophoresis, sequencing, or other methods. PCR

Nitrogen assimilation
Nitrogen assimilation is the formation of organic nitrogen
compounds like amino acids from inorganic nitrogen
compounds present in the environment. Organisms like
plants, fungi and certain bacteria that cannot fix nitrogen
gas (N2) depend on the ability to assimilate nitrate or
ammonia for their needs. Other organisms, like animals,
depend entirely on organic nitrogen from their food.
Gel electrophoresis
Gel electrophoresis is a method for separation and analysis
of macromolecules (DNA, RNA and proteins) and
their fragments, based on their size and charge.
Chromatography
Chromatography is a laboratory technique used to separate mixtures by exploiting differences in how components partition between a stationary and mobile phase. The document discusses various chromatography techniques including column chromatography, planar chromatography like paper and thin layer chromatography, displacement chromatography, gas chromatography using a gas mobile phase, liquid chromatography using a liquid mobile phase like HPLC, and affinity chromatography which uses specific non-covalent interactions for purification. Key terms related to chromatography components and processes are also defined.

lehninger(sixth edition) Ch 01: The foundations of biochemistry
This document provides an overview of key topics in biochemistry including:
1) The structures and functions of prokaryotic and eukaryotic cells.
2) Organic chemical bonds and functional groups that make up biomolecules.
3) The evolution of cells through endosymbiosis and the evolution of proteins through gene duplication events.
4) Central concepts like the genetic code, DNA replication, transcription, translation and the flow of genetic information.
Overview of cells and organ of immune system
The immune system consists of primary and secondary lymphoid organs. The primary organs, bone marrow and thymus, are responsible for the development and maturation of immune cells from hematopoietic stem cells. The secondary organs, including spleen, lymph nodes, and mucosa-associated lymphoid tissue, are where immune responses are initiated through interactions between lymphocytes and antigens. Hematopoietic stem cells in the bone marrow differentiate into mature blood cells, including lymphocytes, which then travel to secondary organs to carry out immune functions.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UP
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.
