Enamines act as nucleophiles that require less acid/base activation for reactivity than their enolate counterparts. They have also been shown to offer a greater selectivity with less side reactions. There is a gradient of reactivity among different enamine types, with a greater reactivity offered by ketone enamines than their aldehyde ...
DNA and RNA also contain other (non-primary) bases that have been modified after the nucleic acid chain has been formed. In DNA, the most common modified base is 5-methylcytosine (m 5 C). In RNA, there are many modified bases, including those contained in the nucleosides pseudouridine (Ψ), dihydrouridine (D), inosine (I), and 7-methylguanosine ...
Free base (freebase, free-base) is a descriptor for the neutral form of an amine commonly used in reference to illicit drugs. The amine is often an alkaloid , such as nicotine , cocaine , morphine , and ephedrine , or derivatives thereof.
The different stages of the method are lyse, bind, wash, and elute. [1] [2] More specifically, this entails the lysis of target cells to release nucleic acids, selective binding of nucleic acid to a silica membrane, washing away particulates and inhibitors that are not bound to the silica membrane, and elution of the nucleic acid, with the end result being purified nucleic acid in an aqueous ...

Nucleic acid extraction apparatus based on the Tajima pipette [14] [15] (see Fig. 2) are one of the most widespread instruments to perform the Boom method. [ 25 ] The Tajima pipette was invented by Hideji Tajima, [ 14 ] founder and president of Precision System Sciences (PSS) [ 25 ] Inc., a Japanese manufacturer of precision and measuring ...

Huberman describes the effect of alcohol on the gut as a two-hit model: It kills the good bacteria in the gut and disrupts the lining of the gut—releasing bad bacteria into your bloodstream.
