DNA extraction
A popular method of DNA extraction, phenol chloroform method. students can use this method if you have required facilities in your lab.
DNA isolation
1. Genetics plays an important role in medicine through studies of inheritance patterns, gene mapping, analysis of disease mechanisms, and diagnosis/treatment of genetic diseases like gene therapy.
2. DNA isolation involves extracting DNA from samples and separating it from other cell components. It is used for scientific research, medicine like outbreak tracing, and forensic science like identification. Various methods disrupt cells, remove proteins, and recover DNA.
3. DNA purification removes contaminants and avoids DNA degradation. Key steps are cell lysis, contaminant removal through various separation techniques, and DNA concentration. Evaluation assesses concentration, purity through absorbance ratios, and degradation using gel electrophoresis.
Agarose gel electrophoresis
Agarose gel electrophoresisMarudhar Kesari Jain College for Women Vaniyambadi - 635 751, Tamil Nadu, INDIA.
Agarose gel electrophoresis is a method to separate DNA fragments by size using an agarose gel matrix and electric current. Shorter DNA fragments migrate faster and farther than longer ones. DNA is visualized by staining with ethidium bromide and viewing under UV light. Agarose concentration determines resolution, with 0.8% gels best for separating large 5-10kb fragments and 2% for small 0.2-1kb fragments. Applications include estimating DNA size, analyzing PCR products, and separating DNA for further analysis.Dna isolation
This document discusses the key steps in isolating genomic DNA from cells:
1) Cell lysis using a buffer with SDS to break open cell and nuclear membranes and release DNA.
2) Addition of protease to degrade proteins surrounding the DNA.
3) Precipitation of DNA by adding salt to neutralize charges on DNA molecules followed by cold alcohol, which causes the DNA to clump out of solution.
electrophoresis
This document summarizes the principles and techniques of electrophoresis. Electrophoresis involves applying an electric field to move charged biomolecules like proteins and nucleic acids through a gel or liquid medium. It was first developed in the 1930s to study serum proteins. Factors like molecular charge, size, shape and buffer conditions determine electrophoretic mobility. Common applications include protein/nucleic acid analysis and purification. Techniques include agarose gel electrophoresis for DNA/RNA separation by size, and sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) to denature and linearly separate proteins by mass. Isoelectric focusing separates proteins based on their isoelectric point.
Dna extraction
The document discusses various DNA extraction methods from biological samples. It describes organic extraction, non-organic extraction, Chelex extraction, and FTA paper methods. Organic extraction uses phenol-chloroform to remove proteins and isolate DNA, while non-organic extraction uses high salt concentrations. Chelex extraction uses an ion exchange resin to remove ions that degrade DNA. FTA paper allows samples to be stored at room temperature. The minimum DNA quantities needed for different techniques is also discussed.
Tests of significance
This document provides an overview of statistical inference and hypothesis testing. It discusses key concepts such as the null and alternative hypotheses, type I and type II errors, one-tailed and two-tailed tests, test statistics, p-values, confidence intervals, and parametric vs non-parametric tests. Specific statistical tests covered include the t-test, z-test, ANOVA, chi-square test, and correlation analyses. The document also addresses how sample size affects test power and significance.

Coral Reefs: Biodiversity and Beauty at Risk
Coral reefs are the largest structures built by living organisms and are home to 25% of ocean species, yet they are at severe risk. Coral reefs provide many benefits like fisheries, shoreline protection, tourism, and medicines, valued at $233 billion to $1.3 trillion annually. However, threats from overfishing, pollution, disease, bleaching due to warming oceans, and ocean acidification have already damaged many reefs and are projected to severely damage most reefs by 2050 if issues are not addressed.
How Did Scientists discover the properties of electrons
J.J. Thomson discovered electrons through his experiments with cathode ray tubes in 1897. He observed that something was moving from the cathode to the anode, even through a vacuum. To determine if these particles carried an electrical charge, Thomson passed cathode rays through an electric field. He found that the particles were deflected towards the positive plate, indicating they were negatively charged particles. This led Thomson to conclude that the particles, which he named "corpuscles," were subatomic constituents within atoms that could be broken off, contradicting prevailing theories that atoms were indivisible. His discovery of electrons and their negative charge was a major breakthrough in understanding atomic structure.

Cop 19
The document discusses the United Nations Framework Convention on Climate Change (UNFCCC). It was created in 1992 at the Rio Earth Summit to stabilize greenhouse gas concentrations and prevent dangerous anthropogenic interference with the climate system. Nearly every country is party to the UNFCCC, which meets annually to assess climate change progress. The Kyoto Protocol was adopted under the UNFCCC in 1997 and established emissions reduction obligations for developed countries. The goal of the UNFCCC process is for universal participation to efficiently limit future global warming below 2.0°C through a new legally binding climate agreement.
Human population growth
This document discusses human population growth trends over time. It notes that the global human population reached 1 billion in 1830, 2 billion in 1930, 3 billion in 1960, 4 billion in 1975, 5 billion in 1987, 6 billion in 1999, and 7 billion in 2011. It also provides estimates of current birth and death rates worldwide.

It examines some potential problems associated with high population growth, especially in developing countries, including environmental degradation and resource scarcity. Finally, it outlines the demographic transition process and considers predictions for future global population size and stability.
Plate Tectonics II
The document discusses evidence for plate tectonics including measurements over 10 years showing the movement of tectonic plates and geological studies of ocean floor rocks. Volcanoes, earthquakes, and tsunamis are linked to plate tectonic boundaries as plates diverge, converge, or a hot spot rises. Examples include the Hawaiian Islands formed by a hot spot and volcanoes and quakes at the Mid-Atlantic Ridge. Historic quakes like 1989 in San Francisco and tsunamis such as the 2004 Indian Ocean and 2011 Tohoku, Japan events are also summarized.
Plate Tectonics I
This document provides an overview of plate tectonics and the key individuals and discoveries that led to the development of the theory. It discusses Alfred Wegener's idea of continental drift in the early 20th century, which was initially rejected. It then covers the discoveries of the mid-ocean ridge system and magnetic striping of the ocean floor in the 1950s-60s, which provided evidence that the continents are moving and new crust is generated at ocean ridges through seafloor spreading. This led to the acceptance of plate tectonics as a scientific theory to explain geological phenomena.
How Old is Stuff?
The document discusses estimates of the age of the Earth and universe over time. Early estimates based on biblical interpretations placed the Earth's age at around 6000 years. The development of modern geology in the 18th century, led by James Hutton, established that geological processes occurred gradually over long periods, indicating a much older Earth. Radiometric dating techniques now provide precise measurements of billions of years for the Earth, meteorites, and universe based on the decay of radioactive isotopes.
The earth part ii
The document describes the layers that make up the Earth's interior. It discusses the core, mantle, crust, and lithosphere. The core is divided into a solid inner core and liquid outer core. The mantle is below the core and comprises most of the Earth's volume. It is divided into upper and lower mantle. The crust sits atop the mantle and exists in oceanic and continental forms. The lithosphere includes the crust and upper mantle. The document also provides background on the formation of the Earth and different types of rocks.
Coastal Ecosystems
Coastal ecosystems like estuaries, salt marshes, mangroves, and rocky intertidal zones are influenced by gradients in wave exposure and tidal exposure. Experiments by Joe Connell on barnacles in the rocky intertidal showed that distribution patterns are influenced by both abiotic factors like desiccation stress, and biotic interactions like competition. Mangroves have adaptations like aerial roots and pneumatophores that allow them to survive in intertidal soils with low oxygen and high salinity. They provide nurseries for fish and protect coastlines from storms.
Waves
Ocean waves are caused by wind and transfer energy through water, but do not transfer water from place to place. Key characteristics of waves include wavelength, amplitude, height, and period. Wave movement involves an orbital pattern, with energy moving through water in a circular motion. Near shore, waves begin to break as their movement becomes disrupted. Breaking waves can come crashing ashore. Some surfers seek out large storm waves for challenges they present. There is potential to harness wave power as an energy source.
Tides
Tides are caused by the gravitational forces of the moon and sun interacting with Earth's oceans, which creates two bulges of water that result in two high tides and two low tides each day. The changing positions and distances of the moon and sun relative to Earth cause variations in tide heights and times. Spring tides occur during new and full moons when the sun and moon are aligned, producing the highest tides, while neap tides happen when the sun and moon are at right angles, resulting in lower tides.
