Small pieces of moss "stems" or "leaves" are often scattered by the wind, water or animals. If a moss fragment reaches a suitable environment, it can establish a new plant. [ 2 ] They also produce gemmae , for example in the splash-cups of Marchantia polymorpha , [ 3 ] that are easily broken off and distributed.
A small piece of flesh-like tissue, typically lumpy or warty, growing on the testa near the hilum. Contrast aril. caryopsis A dry, indehiscent, one-seeded fruit in which the seed coat is closely fused to the fruit wall, e.g. in most grasses. Casparian strip
Since only a small number of double-strand breaks are tolerated, and only a small number can be repaired, enough ligation failures could be lethal to the cell. Further research implicates the supplementary role of proliferating cell nuclear antigen (PCNA) to DNA ligase I's function of joining Okazaki fragments. When the PCNA binding site on DNA ...
[31] Very small pieces of the planarian, estimated to be as little as 1/279th of the organism it is cut from, can regenerate back into a complete organism over the course of a few weeks. [32] New tissues can grow due to pluripotent stem cells that have the ability to create all the various cell types. [33]
This glossary of biology terms is a list of definitions of fundamental terms and concepts used in biology, the study of life and of living organisms.It is intended as introductory material for novices; for more specific and technical definitions from sub-disciplines and related fields, see Glossary of cell biology, Glossary of genetics, Glossary of evolutionary biology, Glossary of ecology ...
Fragmentation describes the process of splitting into several pieces or fragments. In cell biology, fragmentation is useful for a cell during both DNA cloning and apoptosis. DNA cloning is important in asexual reproduction or creation of identical DNA molecules, and can be performed spontaneously by the cell or intentionally by laboratory ...
"Viroid-like elements" refer to pieces of covalently closed circular (ccc) RNA molecules that do not share the viroid's lifecycle. The category encompasses satellite RNAs (including small plant satRNAs " virusoids ", fungal " ambivirus ", and the much larger HDV -like Ribozyviria ) and "retroviroids".
A cloning vector is a small piece of DNA that can be stably maintained in an organism, and into which a foreign DNA fragment can be inserted for cloning purposes. [1] The cloning vector may be DNA taken from a virus , the cell of a higher organism, or it may be the plasmid of a bacterium.
