In this article we will discuss about the functional aspects and mechanisms of genetic code. Functional Aspects of Genetic Codon: All the amino acids except methionine and tryptophan are specified by more than one codon. Three amino acids—leucine, serine and orginine—are each specified by six different codons. Isoleucine has three codons, and the other amino acids each have either two [...]
The below mentioned article provides notes on Enzyme Linked Immunosorbent Assay (EIA). Enzyme immunoassay (EIA) was first described by Engvall and Perlmann (1971, 1972), and by von Weemen and Schuurs (1971, 1972). The technique was derived from the work of Nakane and Pierce (1967) which showed that antibodies could be labelled with enzymes for use in histochemical staining of tissues [...]
In this article we will discuss about the mechanism of eukaryotic gene expression, particularly in humans. 1. In multicellular organism, each cell expresses a subset of its genes. 2. A cell expresses different genes depending on its growth state or environment. 3. Sometimes gene transcripts are spliced differently in different cells. 4. Each gene carries not only structural information but [...]
