Flanking sequence definition

Short hairpin RNA (shRNA) sequences are usually encoded in a DNA vector that can be introduced into cells via plasmid transfection or viral transduction. shRNA molecules can be divided into two main categories based on their designs: simple stem-loop and microRNA-adapted shRNA. A simple stem-loop shRNA is often transcribed under the control of ...

These regions primarily function in th…Different flanking haplotypes within loci were identified and characterized, and the types and locations of the variants involved were described. The rates of stutter were then contrasted both across loci and across haplotypic backgrounds within loci to assess whether flanking sequence variation, as well as the LUS, influence the rates of stutter.Polymerase chain reaction, or PCR, is a technique to make many copies of a specific DNA region in vitro (in a test tube rather than an organism).
