Production of Biopolymer | Genetics

The commercial production of biopolymer is aimed as bio-degradable alteration to petrochemicals (synthetic) plastics. The homopolymer poly (3-4 hydroxy butyrate) (PHB) shows brittle, whereas copolymer like poly (3-hydroxy butyrate-co-3-hydroxy valerate) (PHBV) are more flexible due to their reduced crystallanity and are well suited for commercial applications. Polyhydroxybutyrate is best characterized polymer synthesized in bacteria Alkaligenes entrophus accumulate upto 70% of [...]

Models for Post-Transcriptional Gene Silencing (PTGS) | Genetics

In this article we will discus about the models for post-transcriptional gene silencing (PTGS). Production of dsRNA from inverted transgene repeats and single copy transgene trig­gers PTGS. It was proposed that dsRNA would be act as template for an RNA-directed RNA polymerase. Atleast four models have been proposed to explain induction of PTGS. First model is known as threshold model [...]
