Polymerase chain reaction (PCR) is a technique used to amplify a single copy of a DNA segment across orders of magnitude, generating thousands to millions of copies. PCR involves repeated cycles of heating and cooling of the DNA sample to denature and separate the DNA strands, followed by primer annealing and polymerase extension. This allows for exponential amplification of the target DNA sequence. PCR is commonly used in clinical and research applications such as disease diagnosis, genetic analysis, and forensic identification.
PCR- Steps;Applications and types of PCR (Exam point of view)
The term PCR stands for Polymerase Chain Reaction.
It is an invitro amplification technique that allows synthesizing millions of copies of the DNA or gene of interest from a single copy.

PCR.pptx
Polymerase chain reaction (PCR) is a powerful method for amplifying DNA sequences. It involves denaturing DNA into single strands, annealing primers to the strands, and extending the primers to replicate the DNA. Key components of PCR include a DNA template, DNA polymerase enzyme, primers, nucleotides, and a thermocycler. The thermocycler regulates temperature changes to allow for denaturation, annealing, and elongation steps that are repeated for numerous cycles to exponentially amplify the target DNA sequence. PCR is commonly used for diagnosing diseases and detecting microorganisms, and variations like real-time PCR, microarray analysis, bridge PCR, and emulsion PCR are employed for different applications like next-generation sequencing.
Polymerase Chain Reaction
PCR (polymerase chain reaction) is a method to analyze a short sequence of DNA (or RNA) even in samples containing only minute quantities of DNA or RNA. PCR is used to reproduce (amplify) selected sections of DNA or RNA.
Polymerase Chain Reaction(PCR) Likhith K
The advent of the polymerase chain reaction (PCR) radically transformed biological science from the time it was first discovered (Mullis, 1990). For the first time, it allowed for specific detection and production of large amounts of DNA. PCR-based strategies have propelled huge scientific endeavors such as the Human Genome Project. The technique is currently widely used by clinicians and researchers to diagnose diseases, clone and sequence genes, and carry out sophisticated quantitative and genomic studies in a rapid and very sensitive manner. One of the most important medical applications of the classical PCR method is the detection of pathogens. In addition, the PCR assay is used in forensic medicine to identify criminals. Because of its widespread use, it is important to understand the basic principles of PCR and how its use can be modified to provide for sophisticated analysis of genes and the genome

Describing and Interpreting an Immersive Learning Case with the Immersion Cub...
Current descriptions of immersive learning cases are often difficult or impossible to compare. This is due to a myriad of different options on what details to include, which aspects are relevant, and on the descriptive approaches employed. Also, these aspects often combine very specific details with more general guidelines or indicate intents and rationales without clarifying their implementation. In this paper we provide a method to describe immersive learning cases that is structured to enable comparisons, yet flexible enough to allow researchers and practitioners to decide which aspects to include. This method leverages a taxonomy that classifies educational aspects at three levels (uses, practices, and strategies) and then utilizes two frameworks, the Immersive Learning Brain and the Immersion Cube, to enable a structured description and interpretation of immersive learning cases. The method is then demonstrated on a published immersive learning case on training for wind turbine maintenance using virtual reality. Applying the method results in a structured artifact, the Immersive Learning Case Sheet, that tags the case with its proximal uses, practices, and strategies, and refines the free text case description to ensure that matching details are included. This contribution is thus a case description method in support of future comparative research of immersive learning cases. We then discuss how the resulting description and interpretation can be leveraged to change immersion learning cases, by enriching them (considering low-effort changes or additions) or innovating (exploring more challenging avenues of transformation). The method holds significant promise to support better-grounded research in immersive learning.
The binding of cosmological structures by massless topological defects
Assuming spherical symmetry and weak field, it is shown that if one solves the Poisson equation or the Einstein field
equations sourced by a topological defect, i.e. a singularity of a very specific form, the result is a localized gravitational
field capable of driving flat rotation (i.e. Keplerian circular orbits at a constant speed for all radii) of test masses on a thin
spherical shell without any underlying mass. Moreover, a large-scale structure which exploits this solution by assembling
concentrically a number of such topological defects can establish a flat stellar or galactic rotation curve, and can also deflect
light in the same manner as an equipotential (isothermal) sphere. Thus, the need for dark matter or modified gravity theory is
mitigated, at least in part.

Phenomics assisted breeding in crop improvement
As the population is increasing and will reach about 9 billion upto 2050. Also due to climate change, it is difficult to meet the food requirement of such a large population. Facing the challenges presented by resource shortages, climate
change, and increasing global population, crop yield and quality need to be improved in a sustainable way over the coming decades. Genetic improvement by breeding is the best way to increase crop productivity. With the rapid progression of functional
genomics, an increasing number of crop genomes have been sequenced and dozens of genes influencing key agronomic traits have been identified. However, current genome sequence information has not been adequately exploited for understanding
the complex characteristics of multiple gene, owing to a lack of crop phenotypic data. Efficient, automatic, and accurate technologies and platforms that can capture phenotypic data that can
be linked to genomics information for crop improvement at all growth stages have become as important as genotyping. Thus,
high-throughput phenotyping has become the major bottleneck restricting crop breeding. Plant phenomics has been defined as the high-throughput, accurate acquisition and analysis of multi-dimensional phenotypes
during crop growing stages at the organism level, including the cell, tissue, organ, individual plant, plot, and field levels. With the rapid development of novel sensors, imaging technology,
and analysis methods, numerous infrastructure platforms have been developed for phenotyping.

hematic appreciation test is a psychological assessment tool used to measure an individual's appreciation and understanding of specific themes or topics. This test helps to evaluate an individual's ability to connect different ideas and concepts within a given theme, as well as their overall comprehension and interpretation skills. The results of the test can provide valuable insights into an individual's cognitive abilities, creativity, and critical thinking skillsThe use of Nauplii and metanauplii artemia in aquaculture (brine shrimp).pptx
Although Artemia has been known to man for centuries, its use as a food for the culture of larval organisms apparently began only in the 1930s, when several investigators found that it made an excellent food for newly hatched fish larvae (Litvinenko et al., 2023). As aquaculture developed in the 1960s and ‘70s, the use of Artemia also became more widespread, due both to its convenience and to its nutritional value for larval organisms (Arenas-Pardo et al., 2024). The fact that Artemia dormant cysts can be stored for long periods in cans, and then used as an off-the-shelf food requiring only 24 h of incubation makes them the most convenient, least labor-intensive, live food available for aquaculture (Sorgeloos & Roubach, 2021). The nutritional value of Artemia, especially for marine organisms, is not constant, but varies both geographically and temporally. During the last decade, however, both the causes of Artemia nutritional variability and methods to improve poorquality Artemia have been identified (Loufi et al., 2024).
Brine shrimp (Artemia spp.) are used in marine aquaculture worldwide. Annually, more than 2,000 metric tons of dry cysts are used for cultivation of fish, crustacean, and shellfish larva. Brine shrimp are important to aquaculture because newly hatched brine shrimp nauplii (larvae) provide a food source for many fish fry (Mozanzadeh et al., 2021). Culture and harvesting of brine shrimp eggs represents another aspect of the aquaculture industry. Nauplii and metanauplii of Artemia, commonly known as brine shrimp, play a crucial role in aquaculture due to their nutritional value and suitability as live feed for many aquatic species, particularly in larval stages (Sorgeloos & Roubach, 2021).
Unlocking the mysteries of reproduction: Exploring fecundity and gonadosomati...
The pygmy halfbeak Dermogenys colletei, is known for its viviparous nature, this presents an intriguing case of relatively low fecundity, raising questions about potential compensatory reproductive strategies employed by this species. Our study delves into the examination of fecundity and the Gonadosomatic Index (GSI) in the Pygmy Halfbeak, D. colletei (Meisner, 2001), an intriguing viviparous fish indigenous to Sarawak, Borneo. We hypothesize that the Pygmy halfbeak, D. colletei, may exhibit unique reproductive adaptations to offset its low fecundity, thus enhancing its survival and fitness. To address this, we conducted a comprehensive study utilizing 28 mature female specimens of D. colletei, carefully measuring fecundity and GSI to shed light on the reproductive adaptations of this species. Our findings reveal that D. colletei indeed exhibits low fecundity, with a mean of 16.76 ± 2.01, and a mean GSI of 12.83 ± 1.27, providing crucial insights into the reproductive mechanisms at play in this species. These results underscore the existence of unique reproductive strategies in D. colletei, enabling its adaptation and persistence in Borneo's diverse aquatic ecosystems, and call for further ecological research to elucidate these mechanisms. This study lends to a better understanding of viviparous fish in Borneo and contributes to the broader field of aquatic ecology, enhancing our knowledge of species adaptations to unique ecological challenges.

Polymerase Chain Reaction
- 2. PCR is a revolutionary method developed by Kary Mullis in the 1980s. Polymerase chain reaction (PCR) is a method widely used in molecular biology to make multiple copies of a specific DNA segment. Using PCR, a single copy (or more) of a DNA sequence is exponentially amplified to generate thousands to millions of more copies of the particular DNA segment. PCR is now a common technique used in medical laboratory and clinical laboratory research for a broad variety of applications including biomedical research and criminal forensics. 2
- 3. PCR is based on using the ability of DNA polymerase to synthesize new strand of DNA complementary to the offered template strand. Because DNA polymerase can add a nucleotide only onto a preexisting 3'-OH group, it needs a primer to which it can add the first nucleotide. This requirement makes it possible to delineate a specific region of template sequence that the researcher wants to amplify. At the end of the PCR reaction, the specific sequence will be accumulated in billions of copies Fact: Almost all PCR applications employ a heat-stable DNA polymerase, such as Taq polymerase, an enzyme originally isolated from the thermophilic bacterium Thermu s aquaticus. 3
- 4. Principle The double stranded DNA of interest is denatured to separate into two individual strands. Each strand is then allowed to hybridize with a primer. The primer-template duplex is used for DNA synthesis. This involves three steps : Denaturation, Renaturation and Synthesis. These three steps are repeated over and again in each cycle for successful DNA replication What does Recombinant DNA say? “I am the hybridized DNA molecule Created by cutting and sealing When introduced into host cells I multiply and code for desired proteins” 4
- 5. Component requirement in PCR The basic required components for PCR are: 1. A target DNA sequence (100-35,000 bp) 2. Two Primers that are complimentary to target DNA region (One for each strand). 3. Four types of Deoxyribonucleotides: dATP, dCTP, dGTP and dTTP. 4. A thermostable DNA polymerase that can withstand up to 95˚C of temperature. Remember : There exists a clear line of difference between nucleotides and nucleosides. • Nucleosides are Base + Sugar whereas • Nucleotides are Base + Sugar + Phosphate group 5
- 6. Steps of PCR 1. Denaturation : The temperature is raised to 95˚C for about 1 minute. This causes separation of two DNA strands called Denaturation. 2. Renaturation : Temperature is slowly cooled to about 55˚C which results into binding of primers onto DNA strands. 3. Synthesis : The initiation of DNA synthesis occurs at 3’ end which extends by joining of complimentary bases to template DNA strands at a temperature of about 75˚C. Reaction can be stopped by raising the temperature to 95˚C. 6

- 8. Applications of PCR Prenatal diagnosis of Inherited diseases. Diagnosis of retroviral infections. Diagnosis of bacterial infections. Diagnosis of several virally induced cancers. Also used for sex determination of embryos. A widely used tool in forensics for criminal identification. Also applied in evolutionary biological studies thus, important for palaentology and archeology. 8
