S gene complex
(Science: molecular biology) genes coding for molecular components of the pollen stigma recognition system in the cabbage genus brassica). The gene products govern the self incompatibility response and include a glycoprotein found on the stigma surface and a lectin on the pollen grain surface that binds to the stigma glycoprotein.
Genes are expressed through the process of protein synthesis. This elaborate tutorial provides an in-depth review of the different steps of the biological production of protein starting from the gene up to the process of secretion. Also included are topics on DNA replication during interphase of the cell cycle, DNA mutation and repair mechanisms, gene pool, modification, and diseases...
This tutorial presents the benefits and the possible adverse eventualities of genetic engineering. Know more about this topic in this tutorial to be able to articulate the advantages and disadvantages of artificially manipulating genes...
Genes are the blueprint of our bodies, a blueprint that creates a variety of proteins essential to any organism's survival. Find out in this lesson the various factors that affect growth. ..
Homeostasis is the relatively stable conditions of the internal environment that result from compensatory regulatory responses performed by homeostatic control systems. Know the different components of homeostatic control systems, homeostatic regulators, and the various biological processes that homeostasis entail...
