RE: Random vs. Form-wound stator coils for IFDs. Simply buy a motor that is rated for the service it is to perform. In North America, that would be a motor with an MG1 Part 31 endorsement on the nameplate. I'm not familiar with similar endorsements in the IEC world but there may well be one or more.
5a-Reductase (5AR) is the enzyme that catalyzes the conversion of (among others): 1  Testosterone â 5a-DHT. 2  Androstenedioneâ androsterone. 3  Cortisol â allo-tetrahydrocortisol.s early as 1986, it was suspected by some that 5a-DHT might be a primary contributing factor to prostate cancer growth. 15 5a-Reductase (5AR) is responsible for conversion of testosterone to 5a-dihydrotestosterone (5a-DHT).
In molecular biology, the five-prime cap (5â² cap) is a specially altered nucleotide on the 5â² end of some eukaryotic primary transcripts such as precursor messenger RNA.n eukaryotes, the capping enzyme complex (CEC) required for capping is found bound to RNA polymerase II before transcription starts. As soon as the 5â² end of the new transcript emerges, the enzymes transfer to it and begin the capping process (this kind of mechanism ensures capping, as with polyadenylation).
