How Early Life Thrived Without Oxygen - BioTechniques
Jan 11, 2017 · According to Planavsky, oxygen saturated the surface of oceans and the atmosphere, but these sulfur-oxidizing bacteria thrived best at the interface between oxic and oxygen-poor waters. The evolution of the environment changed the course of evolution for most life on Earth. “A lot of people don’t think about how the Earth has changed so ...
Western Blotting Summary - BioTechniques
Western blotting (or immunoblotting) is a well-established biochemical technique that detects specific proteins in complex samples and has applications from basic research to the diagnosis of infectious diseases. Western blotting can be used to determine quantity, molecular weight and post-translational modifications of proteins and can ...
Protecting the powerhouse of the cell - BioTechniques
Jan 11, 2019 · The mitochondria, often labeled the powerhouse of the cell, are the organelle responsible for energy production within the cell. Playing an important role in cellular respiration, the mitochondria are the main location for ATP production. They also make proteins essential for DNA metabolism such as the iron-sulfur family of proteins.
A Mechanism for Positive Phototropism: Explained - BioTechniques
Nov 23, 2023 · Even without eyes, most organisms are capable of determining the direction light is coming from. In plants, blue-light-absorbing phototropin photoreceptors are responsible for detecting light, enabling them to grow towards it or position their leaves in its path, a phenomenon known as positive phototropism. While the detection of light and the ...

Environmental DNA Extracted From Paw Prints in Snow
Dec 13, 2023 · The team collected snow from the tracks of Alaskan polar bears and Swedish Eurasian lynxes both in the wild and in captivity. They then melted and filtered the snow, extracting environmental DNA before conducting microsatellite analyses. They also collected saliva, hair and mucus to confirm that the genotypes provided by the snow were accurate.
Do Identical Twins Have the Same DNA? - BioTechniques
Nov 26, 2018 · There is a common misconception that identical twins have identical DNA and, though they begin development with a matching genetic blueprint, differences in gene expression throughout life means that they differentiate more and more as they age. Though still more similar than ordinary siblings, they are no longer as identical as one may believe ...
What is Western Blotting? The Story of the Western Blot
Jul 18, 2018 · The technique involves the identification and characterization of DNA-binding proteins using DNA probes (Southern) and protein blotting (western) and was first described in 1980. This method was published before the western blot. Yet, it still alludes to it in its name, reaffirming the popularity of the western blot.
What is the Maillard Reaction? the Science of Cooking
Nov 20, 2018 · The Maillard reaction is a process ubiquitous in the culinary world, it occurs every time you make toast, bake cookies and roast meat, but to most people it is simply known as ‘browning’, a name that only really addresses one of its effects. The Maillard reaction, named after French chemist Louis-Camille Maillard in 1910, is responsible for ...
