DNA contains all the genetic information of an organism that is passed from one generation to the next through inheritance. DNA is made up of nucleotides containing four bases that provide the code for an organism's traits. During cell division and reproduction, DNA is copied and passed from parents to offspring in the form of genes on chromosomes, allowing inheritance of physical and behavioral characteristics.

This document provides information on genetics and DNA. It discusses that DNA is found coiled in chromatin in the nucleus of cells. During cell division, chromatin coils tightly to form chromosomes which are duplicated so each new cell contains a full set. DNA is made of nucleotides containing a sugar, phosphate, and one of four nitrogenous bases. The bases bond with each other to form the sides of the DNA double helix structure. Experiments by Griffith, Hershey and Chase provided evidence that DNA is the genetic material. Watson and Crick used evidence from Franklin and others to develop the first model of the DNA double helix structure. DNA holds the instructions for development and reproduction and can replicate itself through semiconservative replication.

Dna (deoxyribonucleic acid) structure and functions
DNA provides the genetic blueprint for all living organisms. It is made up of four nucleotide bases - adenine, guanine, cytosine, and thymine - that are linked together in a double helix structure. The double helix allows DNA to be tightly packaged and also provides a mechanism for DNA replication. DNA stores genetic information that is passed from parents to offspring, enabling inheritance of traits. It also contains instructions for building and sustaining all life.
Biotechnology and its fundamental final (1).ppt
DNA carries genetic information and consists of two strands linked by hydrogen bonds between complementary nucleotide base pairs. DNA can be cloned by inserting a foreign gene into a bacterial plasmid, which is then taken up by bacteria and replicated along with the plasmid. This results in multiple copies of the gene of interest that can be harvested and used for research or applications such as producing therapeutic proteins.

DNA - Poster
In this poster you are going to be exposed to the DNA structure, composition and information it contains. Can you imagine that you have a nucleus in each cell and within that nucleus is a full strand of DNA. However there is an exception for the gamete [sex cells] which contain only half [1/2] the genetic/DNA a normal cell should have. These are also known as haploid cells.

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.
Applied Science: Thermodynamics, Laws & Methodology.pdf
When I was asked to give a companion lecture in support of ‘The Philosophy of Science’ (https://shorturl.at/4pUXz) I decided not to walk through the detail of the many methodologies in order of use. Instead, I chose to employ a long standing, and ongoing, scientific development as an exemplar. And so, I chose the ever evolving story of Thermodynamics as a scientific investigation at its best.
Conducted over a period of >200 years, Thermodynamics R&D, and application, benefitted from the highest levels of professionalism, collaboration, and technical thoroughness. New layers of application, methodology, and practice were made possible by the progressive advance of technology. In turn, this has seen measurement and modelling accuracy continually improved at a micro and macro level.
Perhaps most importantly, Thermodynamics rapidly became a primary tool in the advance of applied science/engineering/technology, spanning micro-tech, to aerospace and cosmology. I can think of no better a story to illustrate the breadth of scientific methodologies and applications at their best.

Deep Software Variability and Frictionless Reproducibility
Deep Software Variability and Frictionless ReproducibilityUniversity of Rennes, INSA Rennes, Inria/IRISA, CNRS
The ability to recreate computational results with minimal effort and actionable metrics provides a solid foundation for scientific research and software development. When people can replicate an analysis at the touch of a button using open-source software, open data, and methods to assess and compare proposals, it significantly eases verification of results, engagement with a diverse range of contributors, and progress. However, we have yet to fully achieve this; there are still many sociotechnical frictions.
Inspired by David Donoho's vision, this talk aims to revisit the three crucial pillars of frictionless reproducibility (data sharing, code sharing, and competitive challenges) with the perspective of deep software variability.
Our observation is that multiple layers — hardware, operating systems, third-party libraries, software versions, input data, compile-time options, and parameters — are subject to variability that exacerbates frictions but is also essential for achieving robust, generalizable results and fostering innovation. I will first review the literature, providing evidence of how the complex variability interactions across these layers affect qualitative and quantitative software properties, thereby complicating the reproduction and replication of scientific studies in various fields.
I will then present some software engineering and AI techniques that can support the strategic exploration of variability spaces. These include the use of abstractions and models (e.g., feature models), sampling strategies (e.g., uniform, random), cost-effective measurements (e.g., incremental build of software configurations), and dimensionality reduction methods (e.g., transfer learning, feature selection, software debloating).
I will finally argue that deep variability is both the problem and solution of frictionless reproducibility, calling the software science community to develop new methods and tools to manage variability and foster reproducibility in software systems.

The debris of the ‘last major merger’ is dynamically young
The Milky Way’s (MW) inner stellar halo contains an [Fe/H]-rich component with highly eccentric orbits, often referred to as the
‘last major merger.’ Hypotheses for the origin of this component include Gaia-Sausage/Enceladus (GSE), where the progenitor
collided with the MW proto-disc 8–11 Gyr ago, and the Virgo Radial Merger (VRM), where the progenitor collided with the
MW disc within the last 3 Gyr. These two scenarios make different predictions about observable structure in local phase space,
because the morphology of debris depends on how long it has had to phase mix. The recently identified phase-space folds in Gaia
DR3 have positive caustic velocities, making them fundamentally different than the phase-mixed chevrons found in simulations
at late times. Roughly 20 per cent of the stars in the prograde local stellar halo are associated with the observed caustics. Based
on a simple phase-mixing model, the observed number of caustics are consistent with a merger that occurred 1–2 Gyr ago.
We also compare the observed phase-space distribution to FIRE-2 Latte simulations of GSE-like mergers, using a quantitative
measurement of phase mixing (2D causticality). The observed local phase-space distribution best matches the simulated data
1–2 Gyr after collision, and certainly not later than 3 Gyr. This is further evidence that the progenitor of the ‘last major merger’
did not collide with the MW proto-disc at early times, as is thought for the GSE, but instead collided with the MW disc within
the last few Gyr, consistent with the body of work surrounding the VRM.

ESR spectroscopy in liquid food and beverages.pptx
With increasing population, people need to rely on packaged food stuffs. Packaging of food materials requires the preservation of food. There are various methods for the treatment of food to preserve them and irradiation treatment of food is one of them. It is the most common and the most harmless method for the food preservation as it does not alter the necessary micronutrients of food materials. Although irradiated food doesn’t cause any harm to the human health but still the quality assessment of food is required to provide consumers with necessary information about the food. ESR spectroscopy is the most sophisticated way to investigate the quality of the food and the free radicals induced during the processing of the food. ESR spin trapping technique is useful for the detection of highly unstable radicals in the food. The antioxidant capability of liquid food and beverages in mainly performed by spin trapping technique.

DNA and it's role in inheritance pptx.pdf
- 1. ● Presented by: Sawera Rasheed (24) Sehrish (25) ● Topic: DNA and it's role in inheritance
- 2. DNA ● The macromolecule that stores all of an organism’s genetic information. ● DNA is a type of nucleic acid. ● Important property of DNA is that it can replicate or make copies of itself. ● Chromosome is a long, coiled piece of DNA. ● Gene is segment of DNA that codes for speci c trait or protein.
- 3. ● DNA is important for not only humans but also for other organisms. ● Every cell in person's body has same DNA. ● Structure of DNA was established by Watson and Crick in 1953. ● Complete set of DNA is called genome. It contain 3 billion bases, 20,000 genes, 23 pairs of chromosomes. ● Inheritance is transmission of information from one generation to another.
- 5. Types of DNA Nuclear DNA ● Most DNA is located in cell nucleus, called nuclear DNA. ● It is combination of both your ancestor's DNA. Mitochondrial DNA ● Small amount of DNA can also be found in mitochondria, called mitochondrial DNA. ● Which you can only get from your mother.
- 7. How genes are inherited? ● One copy is inherited from mother (via eggs) and other from father (via sperm). ● Sperm and egg each contain one set of 23 chromosomes ● When sperm fertilizes egg 2 copies of each chromosome are present ( and therefore 2 copies of gene ) and so an embryo forms.
- 9. What role does DNA play in inheritance? ● It packs in all the genetic information and passes it onto the next generation. ● DNA make gene, gene make chromosomes.
- 10. DNA and it's role in inheritance ● DNA contain tons of information and is actually very long. If you took all the DNA out of one of your cell and stretched it out, it would be about 5 feet long. This is why DNA condenses into chromosome to t inside the cell. ● The information in DNA is stored as a code made up of four chemical bases. 1. Adenine (A). 2. Cytosine (C) 3. Thyamine(T). 4. Guanine(G)
- 12. ● These four bases control everything about an organism from hair color to number of legs. ● Human DNA consist of 3 billion bases connected together. ● More than 99% of these bases are same in all people. ● They are all sorted in just 23 pairs of chromosomes. ● The order or sequence of these bases determine the information available for building and maintaining an organism. ● DNA bases pair up with eachother, A with T, C with G to form units called base pairs.
- 13. ● Each base is attached to sugar molecule and a phosphate molecule. ● Together a base, sugar and a phosphate is called nucleotide. ● Nucleotides are arranged in 2 long strands that form a spiral called double helix. ● Order of nucleotide in an organism's DNA results in physical and even some behavioural characteristics of an organism.
- 14. Questions regarding topic Q1 : De ne the terms, DNA, gene, chromosome, inheritance, nucleotide, double helix, base pairs, genome. Q2 : How genes are inherited? Q3 : What role does DNA play in inheritance? Q4 : What is the role of nucleotide and four chemical bases? Q5 : Why do you resemble one parent so much but not other?
