The human gene encoding for titin is located on the long arm of chromosome 2 and contains 363 exons, which together code for 38,138 amino acid residues (4200 kDa). [15] ...
A plant cell wall was first observed and named (simply as a "wall") by Robert Hooke in 1665. [3] However, "the dead excrusion product of the living protoplast" was forgotten, for almost three centuries, being the subject of scientific interest mainly as a resource for industrial processing or in relation to animal or human health.
An image of multiple chromosomes, taken from many cells. Plant genetics is the study of genes, genetic variation, and heredity specifically in plants. [1] [2] It is generally considered a field of biology and botany, but intersects frequently with many other life sciences and is strongly linked with the study of information systems.
Even the smallest proteins contain no fewer than 20 amino acids, making for some pretty long names in their own right; titin, however, is the human body’s largest protein. Total amino acid count ...
Transformation of animal and plant cells was also investigated with the first transgenic mouse being created by injecting a gene for a rat growth hormone into a mouse embryo in 1982. [10] In 1897 a bacterium that caused plant tumors, Agrobacterium tumefaciens , was discovered and in the early 1970s the tumor-inducing agent was found to be a DNA ...
This list of longest species names lists the longest scientific binomials. [1] Species in this list are grouped by length of their name. Only binomials are considered, not subgenera, trinomial names of subspecies or infraspecific names. Family is given for each species (or the closest taxonomic rank if family is unassigned), with a short ...
Transfer cells are specialized parenchyma cells that have an increased surface area, due to infoldings of the plasma membrane. They facilitate the transport of sugars from a sugar source, mainly mature leaves, to a sugar sink, often developing leaves or fruits. They are found in nectaries of flowers and some carnivorous plants.
Horizontal transfer of mitochondria is mediated by actin-rich membrane protrusions named tunneling nanotubes (TNTs). [5] The establishment of a nanotube begins with the formation of a filopodium-like membrane protrusion that retracts after reaching the recipient cell, leaving an ultrafine structure that is separated from the substrate.
