Gene targeting is a method for modifying the structure of a specific gene without removing it from its natural environment in the chromosome in a living cell. This process involves the construction of a piece of DNA, known as a gene targeting vector,...

The ability of a bacterium to regulate the expression of the myriad of genes contained in the chromosome and plasmids is essential to the growth and survival of the microorganism. While a bacterium has many genes that code for a variety of proteins,...

The regulation of the genes in prokaryotes and eukaryotes determines the cell's growth, differential development, and responses to changing conditions. In eukaryotes, for example, hormone-producing cells in the human pituitary gland normally only...

To understand the regulation of genes, the following sequence of events must be appreciated: A gene, made of DNA, is "transcribed" to produce a messenger RNA, or mRNA, that is "translated" to produce a protein product. Gene...

Major brassinosteroid (BR) effects such as BR-induced growth are mediated through genomic pathways because RNA synthesis inhibitors and protein synthesis inhibitors interfere with these processes. A limited number of BR-regulated genes have been identified hitherto. The majority of genes (such as BRUL, CycD3, Lin6,...

Amino Acid Regulation of Gene Expression1,2 ABSTRACT Regulation of gene expression by amino acids is mediated through a number of mechanisms affecting both the transcription of DNA and the translation of mRNA. This report reviews recent findings demonstrating a role for amino acids...
