WebIn addition, there is a chance that the transgene DNA, when microinjected into the fertilized egg, may insert itself into the genome in a way that disrupts the animal's normal gene function. If this happens, it can lead to birth defects, poor brain development, cancer, arthritis, diabetes, or other health problems. WebMicroinjection is a direct method to introduce DNA into either cytoplasm or nucleus. It is a microsurgical procedure conducted on a single cell, using a glass needle (i.e., a fine, glass microcapillary pipette), a precision positioning device (a micromanipulator) to control the movement of the micropipette, and a microinjector. geforce rtx 3070 treiber
