Zinc is also present in some denture adhesive creams at levels ranging from 17â34 mg/g [17]. While use of these products as directed (0.5â1.5 g/day) is not of concern, chronic, excessive use can lead to zinc toxicity, resulting in copper deficiency and neurologic disease.
If you're looking to learn about cells with a nucleus, this is the wrong place. Prokaryotes do not have an organized nucleus. Their DNA is kind of floating around the cell. It's clumped up, but not inside of a nucleus. If you want to learn about cells with a nucleus, look for information on eukaryotes. And, once again, a prokaryote is a single cell or organisms that does NOT have organized nuclei.
Report Abuse. Prokaryotes are organisms that lack a cell nucleus or karyona or organelles. Most prokaryotes are unicellular, wheareas eukaryotes are always multicellular. Among the prokaryotes, you can find the bacteriae and the archae.In prokaryotes, the genetic information is not membrane-bound, in other words their DNA is not in their cell.eport Abuse.
