5 minute DNA Extraction in a Shot Glass

A blog that offers research to help you achieve and maintain health… "If we don't play God, who will?" – James Watson Intro: 5 minute DNA Extraction in a Shot Glass Despite its exotic-sounding name, DNA is ubiquitous – it can be found in every cell of every living thing and almost everywhere on the planet. Nonetheless, we rarely come face-to-face with the molecule itself – and it’s not because DNA is difficult to find or isolate! In this instructable, we’ll show you how to isolate your own DNA with little more than some dish soap, table salt, high-proof alcohol, a shot glass, and [more...]

Science Webulagam: Ribonucleic acid (RNA)

Ribonucleic acid (RNA) is a biologically important type of molecule that consists of a long chain of nucleotide units. Each nucleotide consists of a nitrogenous base, a ribose sugar, and a phosphate. RNA is very similar to DNA, but differs in a few important structural details: in the cell, RNA is usually single-stranded, while DNA is usually double-stranded; RNA nucleotides contain ribose while DNA contains deoxyribose (a type of ribose that lacks one oxygen atom); and RNA has the base uracil rather than thymine that is present in DNA. RNA is transcribed from DNA by enzymes called RNA [more...]

Why is the germ ideal for DNA extraction? (in a wheat seed)?

A seed is basically just an egg. The “germ” of a grain is the actual embryo within the seed, while the majority of the rest of the seed is fuel that the new plant will use for its initial growth, and is basically little more than starches and sugars. In short, ALL the DNA in the seed is in the [more...]

How Sugar Destroys Your Health And Can Make You Desperate For Help ...

Sugar is a silent killer, affecting so many aspects of your health, not just fertility. Below you will find a list of reasons why sugars and sweeteners of any kind would best be excluded from your day-to-day routine. You may be saying, “Fine, I already know sugar is not good for me but I CAN’T HELP IT! I just have to eat it”. One of the main reasons for this is that sugar is INCREDIBLY addictive. The more you eat it, the more you want to eat it and the never-ending cycle goes on. There are a few good reasons why intense sugar cravings happen: nutrient deficiencies (particularly [more...]

Genetics is the study of how traits are passed on from one generation to the next via genes (in DNA) and epi is a prefix indicating essentially “related to but not of” (from the Greek preposition meaning on, around, above, nearby, outer, etc.), so epigenetics concerns those phenomena that result in traits being passed from one generation to the next that are not directly due to genetic material alone. In other words, those things that affect the phenotype without affecting the genotype (for those of you in High School biology). Epigenetics has been a hot field in mental health research [more...]

Inquiring minds. Inspiring solutions | UTS News Room

Her early research linked cell division to the process of DNA replication and she is currently working on uncovering, at the molecular level, how cells know to divide at exactly the right place. “Once we understand this process we can work out how to stop the bacteria from multiplying, which will stop an infection from starting and spreading. We can do this by designing novel antibiotics that target specific bacteria – hopefully meaning a significant reduction in bacterial infectious disease.” Associate Professor Liz Harry Harry believes her discoveries could even lead to potential [more...]

A GMO primer — What you should know about genetically modified ...

Ninety-five percent of the sugar-beet crop in the U.S. is genetically modified, but a recent federal ruling may have a huge impact on that. When it all began: The technologies that led to genetically modified foods were developed in the 1970s, with the advent of recombinant DNA technology. At the time, there were a lot of ethical debates and concerns about crossing the species barrier and transgenic technology. The focus then was on bacteria — mainly E. coli — and putting genes from different species into bacteria. Big Business: In the 1980s, Monsanto pushed to develop and use GM [more...]

Losing Weight after 45 is a Bitch: It's Non-GMO Month!!!

GMOs are products of biotechnology (also called genetic engineering or GE), which creates new combinations of plant, animal, bacteria and viral genes by combining DNA from one species with DNA from another. The result: new organisms that do not occur in nature. In short, GMOs are the ultimate processed foods. Beets and corn are two crops that have been compromised by genetic engineering, and now we have the threat of a Franken Salmon reaching our dinner plates. Why should we care about eating GMO foods if we're trying to lose weight? Well, if any of you have gotten anywhere on your weight [more...]

Atheism Mathematically Impossible | OrthodoxNet.com Blog

DNA, the genetic code, also is made up of various smaller molecules (nucleic acids) that have to be together in a precise sequence in order for the DNA to work. There are left-handed and right-handed sugar molecules making-up nucleic acids. In order to get a working DNA molecule the various nucleic acids have to be not only in a precise sequence but they also have to contain only right-handed sugar molecules. If a nucleic acid with a left-handed sugar molecule gets into the mix then the DNA won’t work. The great and well-known British scientist Frederick Hoyle showed that the probability of [more...]

Free Online Guides: New role for master regulator in cell ...

Unlike genetic changes, which involve a change or mutation in DNA sequence, epigenetic changes in the nucleus leave the DNA sequence unaltered but modify the histone proteins, which comprise the backbone of the chromosome. Histones are proteins found in the nucleus that package and order DNA into structural units. Epigentic changes alter how DNA folds in chromosomes, changing how accessible genes are to regulatory proteins and enzymes that copy genes into RNA messages."Epigenetics is the study of how factors outside of actual DNA interact with, but not alter, genes.

Junk DNA: When The Science Hits The Fan -- Changes Edition

Carotenoids are made and reside in chloroplasts along with chlorophyll. These yellow and orange pigments are always present, however the number of chlorophyll molecules far outnumbers the amount of carotenoid molecules. Therefore, the green chlorophyll color masks the yellow and orange pigments during the growing seasons. As the nights get longer, chlorophyll production comes to a halt and all of the residual chlorophyll in the leaf is broken down. When this happens, the underlying carotenoid pigments become visible. Anthyocyanin is the last major type of pigment present in leaves. In [more...]

DNA or RNA friendship necklaces - Boing Boing

Genes are written in DNA and RNA molecules using a code of chemical units called bases. These bases form pairs, which is critical to their function. In DNA, A (adenine) pairs with T (thymine) and G (guanine) pairs with C (cytosine). In RNA, G pairs with C and A pairs with U (uracil). The charms are based on shapes of the base molecules. They are strung onto a chain at the place where they would normally connect to the sugar-phosphate backbone. This set of two necklaces comes with your choice of A-T, A-U, or G-C.
