Chapter Part of the MIT Biology Hypertextbook, this chapter looks at prokaryotic gene regulation, specifically the Lac Operon and also methods for studying regulation, other types of operons and there are also some practice problems. Protein Synthesis Learn all about protein synthesis, the structure of hemolglobin, amino acids, proteins, transcription, and the genetic code. The Lac Operon Part of MIT Biology Hypertextbook web site. Learn about gene regulation and the lac operon. This FAQ covers common cat colors, basic color terminology, and color genetics.
Domestic cats exhibit a rich variety of coat patterns and colors.
The names given to these colors and patterns are increasingly based on genetic theory. Coat Color and Pattern Genetics of the Domestic Cat Viewed in slide format, this site, with the use of colour photos, examines the genetic variations found in domestic cats. Also examines pleitropy, tail length, and fur length genes. This site looks at the types of gene interactions. An easy to read site, it explains the differences between incomplete dominance, codominance, multiple alleles, pleiotropy and polygenic inheritance.
