perception to transcriptional regulation of primary cytokinin-responsive genes in Arabidopsis thaliana. Membrane-bound histidine kinases‚ including CRE1/ AHK4‚ AHK2‚ and AHK3‚ perceive cytokinins. The signal is then transferred via histidine-containing phosphotransfer factors‚ AHPs‚ to transcription-factor-type response regulators‚ such as ARR1‚ which execute the signal-dependent transactivation of primary cytokinin-responsive genes‚ including those for other types of response regulator.

physiological condition. It includes all the mRNA transcripts in a cell‚ reflecting genes that are actively expressed at any given time. An understanding of the transcriptome is essential for interpreting the functional elements of the genome and the development and disease. The key aims of transcriptomics are: cataloguing all species of transcript; determining gene transcriptional structure; and quantifying expression levels of each transcript during development and under different conditions (Marguerat

article An On/Off Switch For Genes written by Jim Kozubek‚ he talks about how doctors are looking at ways to have genes treat different hereditary illnesses. He explains that the gene therapy’s history is not always easy because scientist cannot control where the new gene is inserted. This then causes problems because they need a specific gene to be placed in a certain spot to be read and activated. The started experimenting with the idea of taking a therapeutic gene and combining it with an on/off

Nielsen*‚ M.D.C.M.‚ Ph.D. 1 The idea of human germline gene therapy introducing genetic changes into early embryos which become incorporated into all cells of the body and‚ as such‚ are passed on to future generations - has elicited considerable ethical‚ scientific‚ and political controversy. Technological advances have turned what until recently

Gene Editing Human Embryos While very controversial‚ the fact of the matter is that gene editing on human embryos has happened‚ legally or otherwise. Many people oppose this form of experiments‚ and believe that it is not good for the human race. In theory‚ gene editing could give us the ability to remove certain genes and replace them with genes that could serve the same purpose but in a more efficient manner. While gene editing is not a new process‚ it is not an experiment that has been performed
