Fusion of structural genes to analyze protein behavior or fusion of regulatory sequences with structural genes to determine mechanisms of regulation.  

The phenotypic manifestation of a gene or genes by the processes of gene action. The production of RNA and cellular proteins. The process by which genetic information from the DNA is carried to the RNA and translated into proteins.  

It encodes the major envelope protein and includes all the specifications for HBsAg.  

A genetic rearrangement through loss of segments of DNA or RNA, bringing sequences which are normally separated into close proximity. This deletion may be detected using cytogenetic techniques and can also be inferred from the phenotype, indicating a deletion at one specific locus.  

The asymmetrical segregation of genes during replication which leads to the production of non-reciprocal recombinant strands and the apparent conversion of one allele into another. Thus, e.g., the meiotic products of an Aa individual may be AAAa or aaaA instead of AAaa, i.e., the A allele has been converted into the a allele or vice…

A product formed from skin, white connective tissue, or bone collagen. It is used as a protein food adjuvant, plasma substitute, hemostatic, suspending agent in pharmaceutical preparations, and in the manufacturing of capsules and suppositories. A jellylike material obtained from boiling animal skin, ligaments, and bones. A protein found in collagen which is soluble in…

Endoscopic examination, therapy, or surgery of the interior of the stomach. Visual examination of the stomach using a gastroscope. Visual examination of the stomach (esp. the upper part) by means of a flexible fiberoptic instrument (gastroscope) inserted through the esophagus; photographs may be taken and specimens removed for analysis. Visualization of the esophagus, stomach, and…

The digestive pathway, including the esophagus, stomach, small intestine, and large intestine. Flexible muscular tube from the mouth, through the esophagus, stomach, small intestine, large intestine, and rectum to the anus. Stomach and intestines; sometimes used more broadly to include the entire digestive tube from the mouth to the anus. The passage along which the…

Refers to the stomach and intestines. Pertaining to the stomach and intestines. Pertaining to both the stomach and the intestines.    

Flow of the stomach’s contents back up into the esophagus. Happens when the muscle between the esophagus and the stomach (the lower esophageal sphincter) is weak or relaxes when it shouldn’t. May cause esophagitis. Also called esophageal reflux or reflux esophagitis. Gastroesophageal reflux disease, also known as GERD, is a condition in which acidic gastric…
