Transformation using electroporation was developed in the late 1980s, increasing the efficiency of in-vitro transformation and increasing the number of bacterial strains that could be transformed. [9] Transformation of animal and plant cells was also investigated with the first transgenic mouse being created by injecting a gene for a rat growth hormone into a mouse embryo in 1982. [10] In 1897 a bacterium that caused plant tumors, Agrobacterium tumefaciens, was discovered and in the early 1970s the tumor-inducing agent was found to be a DNA plasmid called the Ti plasmid. [11] By removing the genes in the plasmid that caused the tumor and adding in novel genes, researchers were able to infect plants with A. tumefaciens and let the bacteria insert their chosen DNA into the genomes of the plants. [12] Not all plant cells are susceptible to infection by A. tumefaciens, so other methods were developed, including electroporation and micro-injection. [13] Particle bombardment was made possible with the invention of the Biolistic Particle Delivery System (gene gun) by John Sanford in the 1980s. [14] [15] [16] Definitions [ edit ] Digital is recognised in the private sector as the core driver of efficiency, but we are only beginning to harness its potential across the UK government. Private companies have reduced costs, sped up delivery times and improved user experience by focusing on end-to-end digital transformation of services, using agile, product-centric ways of working and investing in modern technology and systems. Government must do the same. treatment is also effective for transformation of plasmid DNA. [7] The method of transformation by Mandel and Higa was later improved upon by Douglas Hanahan. [8] The discovery of artificially induced competence in E. coli created an efficient and convenient procedure for transforming bacteria which allows for simpler molecular cloning methods in biotechnology and research, and it is now a routinely used laboratory procedure.

Logarithmically growing bacteria differ from stationary phase bacteria with respect to the number of genome copies present in the cell, and this has implications for the capability to carry out an important DNA repair process. During logarithmic growth, two or more copies of any particular region of the chromosome may be present in a bacterial cell, as cell division is not precisely matched with chromosome replication. The process of homologous recombinational repair (HRR) is a key DNA repair process that is especially effective for repairing double-strand damages, such as double-strand breaks. This process depends on a second homologous chromosome in addition to the damaged chromosome. During logarithmic growth, a DNA damage in one chromosome may be repaired by HRR using sequence information from the other homologous chromosome. Once cells approach stationary phase, however, they typically have just one copy of the chromosome, and HRR requires input of homologous template from outside the cell by transformation. [41] Gene gun: Also referred to as particle bombardment, microprojectile bombardment, or biolistics. Particles of gold or tungsten are coated with DNA and then shot into young plant cells or plant embryos. Some genetic material will stay in the cells and transform them. This method also allows transformation of plant plastids. The transformation efficiency is lower than in Agrobacterium-mediated transformation, but most plants can be transformed with this method.We provide optimal levels of professional massage and bodywork services to promote healing and well being through responsible, compassionate, and respectful touch.

People expect government services to be as good as the best online experiences in the private sector. Rising to meet these expectations will require change on a scale that government has never undertaken before.This roadmap sets out a common cross-government vision for 2025 and a set of specific actions we will collectively take to achieve it. It has been written collaboratively by the Central Digital and Data Office (CDDO) and central government departments. Exceed public expectations. We will create user-centric policies and public services that are more efficient, fit for the digital age, centred on user needs and deliver the right outcomes.
