This PhD will aim to express these silent gene clusters, optimally produce novel antibiotics and genetically engineer pathways to create novel products.
Now team of researchers at Princeton University has announced that it has discovered a global regulator that switches on a lot of silent gene clusters in a bacterium.
Rather than activate the normally silent gene, the mutation silenced the normally active gene, thus thwarting the production of the corresponding proteins in the embryo, Li says.
Moreover, the molecular basis of several genetic variants of BCHE have been reported, such as atypical gene [5], fluoride-resistant gene [6], silent gene [7], K-variant [8], J-variant [9], and H-variant X10].
A phenotypically resistant strain may be genotypically "susceptible," and in contrast, a susceptible phenotype may carry silent genes, which are observed with genotyping [10].
He argues that the so-called "junk DNA" consists of silent genes that are not subject to the normal processes of natural selection and thus can evolve freely over long periods of time without adversely affecting the host organisms.
Singapore, Feb 8, 2013 - (ACN Newswire) - Scientists from Singapore and Germany have identified that the proteins lamin A (Lmna) and lamin B receptor (Lbr) are essential for holding silent genes in their correct position at the edge of the nucleus, in the form of heterochromatin(1).
