You`re one in a googol: optimizing genes for protein expression
You`re one in a googol: optimizing genes for protein expression

... The standard genetic code encodes the 20 ubiquitous amino acids by 61 nucleotide triplets (codons). An amino acid may be encoded by as few as one or as many as six codons. This redundancy means that a protein can be encoded by many alternative nucleic acid sequences; a 300 amino acid protein of aver ...

Messenger RNA reprogramming by spliceosome-mediated

... Consensus sequences at and around the splice sites in nuclear pre-mRNA introns of mammals (17). Two types of introns, U2-dependent and U12-dependent, are spliced by two spliceosomes that share some components. The U2-dependent introns are by far the more prevalent. Although all the published SMaRT r ...

History of genetic engineering

Genetic modification caused by human activity has been occurring since around 12,000 BC, when humans first began to domesticate organisms. Genetic engineering as the direct transfer of DNA from one organism to another was first accomplished by Herbert Boyer and Stanley Cohen in 1973. Advances have allowed scientists to manipulate and add genes to a variety of different organism and induce a range of different effects. Since 1976 the technology has been commercialised, with companies producing and selling genetically modified food and medicine.
