Retroviruses Contain RNA and not DNA - To be able to take over a host cell, the retrovirus must be able to convert the RNA into DNA. -To accomplish the conversion, retroviruses insert an enzyme called Reverse Transcriptase into the host cell RETROVIRUSES Most complicated Genetic information flows...
Mitosis Mitosis is cell reproduction and it occurs in the nucleus of the cell Mitosis enables the cell to make an exact copy of itself Mitosis Mitosis is the process of cell division, which results in the production of two daughter cells from a single parent cell. The daughter cells are ide...
Human R-RAS protein mainly localizes to focal adhesions on the plasma membrane [6], where it regulates integrin functions by enhancing focal adhesion formation, cell adhesion, and cell spreading [7,8]. R-RAS2/TC21 localizes to the plasma membrane and the Golgi apparatus [9,10], suggesting...
Plants, known for their immobility, employ various mechanisms against stress and damage. A prominent feature is the formation of callus tissue—a cellular growth phenomenon that remains insufficiently explored, despite its distinctive cellular plasticity compared to vertebrates. Callus formation involves dedi...
Metabolic engineering approaches initially used chemical mutagenesis-based selection and chemical engineering procedures that centered on manipulating substrate flux; however, the field has since expanded to include other strategies from a genetics standpoint [48,54]. The process varies depending on promoter...
