Define mitochondria. mitochondria synonyms, mitochondria pronunciation, mitochondria translation, English dictionary definition of mitochondria. mitochondrion n. pl. mi·to·chon·dri·a A spherical or elongated organelle in the cytoplasm of nearly all e
A small circular DNA molecule of which all MITOCHONDRIA in cells have several copies. It contains 16,569 base pairs and 37 genes. Being present in the cytoplasm of the cell, is transmitted exclusively by the mother. A mature ovum contains about 100,000 copies of mitochondrial DNA; sperms co...
of the spindle. In telophase, the spindle disappears, and a nuclear membrane forms around the chromosomes at each end of the cell. The cytoplasm of the dividing cell begins to separate during mitosis and ends after division of the nucleus is complete. During interphase, the daughter cells ...
The meaning of SYMBIONT is an organism living in symbiosis; especially : the smaller member of a symbiotic pair.
The meaning of SARCOMERE is any of the repeating, contractile, structural subunits of striated muscle cells (as of skeletal or cardiac muscle) that are composed of the protein filaments actin and myosin. How to use sarcomere in a sentence.
Similar to other biological membranes, the membrane of the endoplasmic reticulum is a lipid bilayer, which means it has two layers of phospholipids, with various membrane proteins and carbohydrates. However, unlike the nucleus, chloroplasts, and mitochondria which have two lipid bilayer membranes (...
Thus, fathers have an important, albeit indirect, influence on the genetic imprinting of mitochondria and thereby on the energy metabolism of their children. FromScience Daily By studying mice with heart failure, the researchers found evidence of stress imprinting on the epigenome, that is, chemical...
import assay assessing mitochondrial and chloroplast imports simultaneously show dual targeting of ascorbate peroxidase, monodehydroascorbate reductase, and glutathione reductase gene products to mitochondria and chloroplasts, while a putative dehydroascorbate reductase protein is only imported into mitochondria. In...
Mitochondrial inheritance --This type of genetic disorder is caused by mutations in the nonchromosomal DNA of mitochondria. Mitochondria are small round orrod-like organelles that are involved in cellularrespirationand found in thecytoplasmof plant and animal cells. Each mitochondrion may contain 5 to...
Moreover, this change in calcium levels occurred not only in the main body of the cell but also within substructures such as mitochondria -- the tiny power plants that cells use to produce energy. FromScience Daily There is a risk that the barges could come into contact with the “substruct...
