Variation in DNA sequence between individuals that is detectable by variation in the length of DNA fragments generated by digestion with restriction endonucleases.
Industry:Natural environment
A database management system with the ability to access data organized in tabular files that can be related to each other by a common field (item). An RDBMS has the capability to recombine the data items from different files, providing powerful tools for data usage.
Industry:Natural environment
A large barrel-shaped colony of colonial pelagic tunicates belonging to the genus Pyrosoma. The colony propels itself through the water by means of cilia that pump water through the individual tunicates. It responds to mechanical, chemical, and light stimuli by moving and by spectacular blue-green bioluminescent displays.
Industry:Natural environment
A nutrient, such as iron, copper, or zinc, that is required in very small amounts by plants in order to photosynthesize and thrive.
Industry:Natural environment
A slender elongated thread-like organ which may cling to objects for support.
Industry:Natural environment
A tide that occurs when the difference between high and low tide is least; the lowest level of high tide. Neap tide comes twice a month, in the first and third quarters of the moon.
Industry:Natural environment
Any of over 40 species of bony fishes in the family Antennariidae. They are small globose fishes with loose prickly skin, limb-like pectoral fins with an elbow-like joint, small round gill openings, and a very large upward directed mouth. The first dorsa.
Industry:Natural environment
DNA sequences that interrupt the protein-coding sequence of a gene; introns are transcribed into mrna but the sequences are eliminated from the RNA before it is used to make protein; junk DNA; in eukaryotic cells, a sequence of DNA that is contained in the gene but does not encode for protein. The presence of introns "splits" the coding region of the gene into segments called exons.
Industry:Natural environment
In relation to the genetic code, more than one codon can code for the same amino acid.
Industry:Natural environment
Newly hatched, active feeding post larval fishes; may include all fish stages from hatching to fingerling.
