While Prokaryotes see some nonessential genes being encoded into extra-chromosomal plasmids‚ such activity is typically absent in Eukaryotic cells. 3. The own way DNA is present in each type of cell has different

doctors in the 1950’s‚ cells from her tumor were sent for research without her consent; and unfortunately the credit/rights that her and her family deserves have been thrown in the air.

ROD CELLS Rod cells‚ or rods‚ are photoreceptor cells in the retina of the eye that can function in less intense light than the other type of visual photoreceptor‚ cone cells. Rods are concentrated at the outer edges of the retina and are used in peripheral vision. On average‚ there are approximately 125 million rod cells in the human retina.[1] More sensitive than cone cells‚ rod cells are almost entirely responsible for night vision. STRUCTURE AND FUNCTION Rods are a little longer and leaner
