In prophase the chromatin, diffuse in interphase, condenses into chromosomes. Each chromosome duplicates and has become two sister chroma...
Genetic Technology and the betterment of our world What exactly is genetic engineering? A simple definition of genetic engineering is ?the ability to isolate DNA pieces that contain selected genes of other species?(Muench 238). Genetic engineering has been the upcoming field of biology since the early nineteen seventies. The prospero...
BACTERIAL CONJUGATION EXPERIMENT INTRODUCTION: Bacteria, in general, reproduce asexually, but in order to increase diversity, they have developed a mechanism for transfer of genetic material from one bacterium to another. The ability to perform this transfer is conferred by a set of genes which are called F for 'fertility.' These genes...
