Example sentences for: pri-mi
How can you use “pri-mi” in a sentence? Here are some example sentences to help you improve your vocabulary:
While this work was under review, the clustering of miR-100, let-7 and miR-125 was independently reported; these researchers also provide evidence for coordinate expression of these miRNAs as a single pri-miRNA [ 45 50 ] .
Processing of pri-miRNA into the pre-miRNA stem-loop occurs in the nucleus, while subsequent processing of pre-miRNA into 21-22 mers is a cytoplasmic event mediated by the RNAse III enzyme Dicer [ 17 18 19 20 ] ; Dicer is also responsible for cleavage of long perfectly double-stranded RNA into 21-22 nucleotide fragments during RNA interference (RNAi) [ 2 21 ] . These latter molecules, known as silencing RNA (siRNA), bind to and trigger the degradation of perfectly homologous mRNA molecules via RISC, a double-strand RNA-induced silencing complex containing nuclease activity [ 22 23 ] .
In general, it is thought that miRNA biogenesis proceeds via intermediate precursor transcripts of more than 70 nucleotides that have the capacity to form an extended stem-loop structure (pre-miRNA), although at least some pre-miRNAs are further derived from even longer transcripts (primary miRNA transcripts, or pri-miRNAs).
Our observation that the temporal expression profile of miR-100 (Figure 5d) is similar to that described for let-7 and miR-125 (that is, expression is initiated during larval/pupal development and continues through adulthood [ 9 29 ] ) is consistent with probable coordinate expression of all three as a single pri-miRNA transcript, and may further implicate miR-100 in developmental timing.
