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.
Section 9.7 Organelle DNAs. Although the vast majority of DNA in most eukaryotes is found in the nucleus, some DNA is present within the mitochondria of animals, plants, and fungi and within the chloroplasts of plants.ndividual mitochondria are large enough to be seen under the light microscope and even the mitochondrial DNA (mtDNA) can be detected by fluorescence microscopy. The mtDNA is located in the interior of the mitochondrion, the region known as the matrix.
