For example, many types of RNA have been ... then inhibit transcription of an mRNA molecule that has a sequence complementary to its RNA component. Inside the eukaryotic nucleus, the nucleolus ...

Our search for additional microRNAs was precipitated by Pasquinelli and Ruvkun's finding that the let-7 RNA sequence is perfectly conserved across a vast evolutionary distance. At that time ...

Twist Bioscience, for example, offers a rapid library preparation kit designed to work ... It also incorporates dUTP nucleotides during second-strand synthesis, allowing scientists to trace amplified ...

This is where DNA and RNA epigenetics comes in: a series of mechanisms that act as "markers" on genes, to control their activity without modifying the DNA or RNA sequence itself. Until now, DNA and ...

Researchers led by François Fuks - Laboratory of Cancer Epigenetics, ULB Faculty of Medicine, ULB-Cancer Research Center and Jules Bordet Institute, H.U.B. - have discovered a new mechanism which ...
