Where is …Features defining a pri-miRNA encompass more than just structure. Sequence motifs like UG and CNNC at the 5′ and the 3′ ends of the basal stem respectively can promote pri-miRNA cleavage by Microprocessor [46, 47]. A bulged GHG motif in the stem and UGUG motif in the loop also contribute to the processing efficiency [46, 48]. About 80% of ...Introns can be divided into three types based on phases: phase 0, phase 1, and phase 2. A phase 0 intron does not disrupt a codon, a phase 1 intron disrupts a codon between the first and second bases, whereas a phase 2 intron disrupts a codon between the second and third bases. An exon flanked by two introns of the same phase is called a ...

Although seemingly simple, this process is relatively new and quite complex. In most cases, gene targeting with the use of floxing is enhanced and catalyzed through a process known as Cre/lox recombination.
