In 2012 a modified RAD tagging method called double digest RADseq (ddRADseq) was suggested. [10] [11] By adding a second restriction enzyme, replacing the random shearing, and a tight DNA size selection step it is possible to perform low-cost population genotyping.
EcoRI (pronounced "eco R one") is a restriction endonuclease enzyme isolated from species E. coli. It is a restriction enzyme that cleaves DNA double helices into fragments at specific sites, and is also a part of the restriction modification system. [1]
In biotechnology applications, T7 RNA polymerase is commonly used to transcribe DNA that has been cloned into vectors that have two (different) phage promoters (e.g., T7 and T3, or T7 and SP6) in opposite orientation.

In May 2020, a separate phylogenomic analysis that used a double digest RADseq protocol (in contrast to the previous studies, which used whole mitogenomes) found that the South Australian form of the Burrunan dolphin fell within T. aduncus, forming a monophyletic lineage that is sister to an undescribed, wider coastal Australasian subspecies ...
Primordial soup, also known as prebiotic soup, is the hypothetical set of conditions present on the Earth around 3.7 to 4.0 billion years ago. It is an aspect of the heterotrophic theory (also known as the Oparin–Haldane hypothesis ) concerning the origin of life , first proposed by Alexander Oparin in 1924, and J. B. S. Haldane in 1929.
Czernina (Polish pronunciation: [t͡ʂɛrˈɲina] ⓘ, from czarny – "black"; also spelled czarnina or czarna polewka – "black soup") is a Polish soup traditionally made of duck blood and clear poultry broth. Rabbit or pig blood can also be used as alternatives. [1] [2] In English it can be called "duck blood soup".
Macaulay's method (the double integration method) is a technique used in structural analysis to determine the deflection of Euler-Bernoulli beams.Use of Macaulay's technique is very convenient for cases of discontinuous and/or discrete loading.
