Second runner credited with a proper documented world run under the World Runners Association rules. He holds the record for the fastest circumnavigation on foot and is the second person to be inducted into the WRA membership. [citation needed] Date Dec. 31, 2011 – Sept. 13, 2013 Duration 1 year, 8 months, 14 days Distance
An image file format is a file format for a digital image. There are many formats that can be used, such as JPEG, PNG, and GIF. Most formats up until 2022 were for storing 2D images, not 3D ones. The data stored in an image file format may be compressed or uncompressed.
On April 25, 1953 James D. Watson and Francis Crick published "a radically different structure" for DNA, [3] thereby founding the field of molecular genetics.Their structural model featured two strands of complementary base-paired DNA, running in opposite directions as a double helix.

A pulsed plasma thruster (PPT), also known as a Pulsed Plasma Rocket (PPR), or as a plasma jet engine (PJE), is a form of electric spacecraft propulsion. [1] PPTs are generally considered the simplest form of electric spacecraft propulsion and were the first form of electric propulsion to be flown in space, having flown on two Soviet probes (Zond 2 and Zond 3) starting in 1964.

These cycles normally consist of three stages: the first, at around 95 °C, allows the separation of the nucleic acid's double chain; the second, at a temperature of around 50–60 °C, allows the binding of the primers with the DNA template; [7] the third, at between 68 and 72 °C, facilitates the polymerization carried out by the DNA polymerase.
Polymerase chain reaction itself is the process used to amplify DNA samples, via a temperature-mediated DNA polymerase.The products can be used for sequencing or analysis, and this process is a key part of many genetics research laboratories, along with uses in DNA fingerprinting for forensics and other human genetic cases.
