An electrochemical cell is a device capable of either generating electrical energy from chemical reactions or facilitating chemical reactions through the introduction of electrical energy. A common example of an electrochemical cell is a standard 1.5 - volt cell meant for consumer use. This type of device is known as a single galvanic cell. A battery consists of one or more cells, connected in either parallel or series pattern.
Most of the DNA in eukaryotes is found in the nucleus, while prokaryotes, lacking a nucleus, have their DNA loose in the cytoplasm. Explanation: In eukaryotes, the genomic DNA, which makes up most of the cells DNA, is contained in the nucleus. There is additional DNA in the cells mitochondria, and still more in the chloroplast if it is a plant cell, but it is a very small amount.
Best Answer: Eukaryotic DNA is found in the nucleus, mitochondria and the plastid. Most eukaryotic DNA is found in the nucleus, usually in the form of chromosomes. The chromosomes exist as uncoiled chromatin during interphase and condense during cell division. Mitochondria and plastids also have their own DNA, found in the form of DNA-protein complexes located on the inner membranes of the plastids.
