The PAX-6 gene is a gene that translates to the PAX-6 protein that serves as a transcription factor needed to activate certain genes that functions in the development of the eyes. While PAX-6 gene may look like it produces different functions for different species (such as formation of the compound eye in insects vs. formation of a single lens eye in vertebrates), it does not. It does in fact only regulate the genes required for the formation of the eyes. Absence or mutation of the PAX-6 gene will cause aniridia or absence of the iris, opaque lens and cornea, and a dysfunctional retina. Also, the function of the PAX-6 protein is conserved throughout evolution of species.
It is known as a transgenic organism. This procedure is otherwise called "genetic engineering." Genes of one species can be altered, or qualities can be transplanted starting with one animal types then onto the next. Genetic engineering is made conceivable by recombinant DNA innovation. Living beings that have modified genomes are known as transgenic.
Vacuoles are storage sacs used for storing liquid and solid contents.they are small in animal cells and large in plant cells.in plant cells vacuoles are full of cell sap and provide turgidity and rigidity to the cell.in single celled organisms like amoeba,the food vacuole contain the food item that amoeba has consumed.in some unicellular organisms specialised vacuoles also play important role in expelling excess water and some waste from the cell.
