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.
  Most of the DNA in a eukaryotic cell is in the nucleus, and that is where DNA replication and transcription occur.In eukaryotic cells, mitochondria and chloroplasts a â¦ lso contain DNA, which performs replication and transcription inside these organelles. In prokaryotic cells there is no nucleus.The DNA is in a region of the cytoplasm called the nucleoid, and that is where DNA replication and transcription occur in these cells.n prokaryotic cells there is no nucleus.
