However, in 1970, Morton Mandel and Akiko Higa showed that E. coli may be induced to take up DNA from bacteriophage λ without the use of helper phage after treatment with calcium chloride solution. [6] Two years later in 1972, Stanley Norman Cohen, Annie Chang and Leslie Hsu showed that CaCl

By delivering against the roadmap, it’s my firm belief we will build the foundations for a better and more productive economy and society. Message from Paul Willmott, Executive Chair, Central Digital and Data Office Shape A has a base of 4 units and shape B has a base of 2 units. 2 is half of 4. The scale factor is 0.5. The lengths of shape B are half the lengths of shape A. Competence is specifically induced by DNA damaging conditions. For instance, transformation is induced in Streptococcus pneumoniae by the DNA damaging agents mitomycin C (a DNA cross-linking agent) and fluoroquinolone (a topoisomerase inhibitor that causes double-strand breaks). [34] In B. subtilis, transformation is increased by UV light, a DNA damaging agent. [35] In Helicobacter pylori, ciprofloxacin, which interacts with DNA gyrase and introduces double-strand breaks, induces expression of competence genes, thus enhancing the frequency of transformation [36] Using Legionella pneumophila, Charpentier et al. [37] tested 64 toxic molecules to determine which of these induce competence. Of these, only six, all DNA damaging agents, caused strong induction. These DNA damaging agents were mitomycin C (which causes DNA inter-strand crosslinks), norfloxacin, ofloxacin and nalidixic acid (inhibitors of DNA gyrase that cause double-strand breaks [38]), bicyclomycin (causes single- and double-strand breaks [39]), and hydroxyurea (induces DNA base oxidation [40]). UV light also induced competence in L. pneumophila. Charpentier et al. [37] suggested that competence for transformation probably evolved as a DNA damage response. Likewise, f(x) can be transformed in many ways. This table shows the resultant graph after the transformation is applied on f(x). Transformation of f(x)

As the Parliamentary Secretary with responsibility for digital government, I remain focused on the targets and commitments we set out last year. I also believe it is essential we stay at the cutting edge of digital and remain relevant. Consequently, I am launching an iteration of the roadmap, which includes additional targets around AI and a heightened focus in several existing areas, agreed with colleagues across departments.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.
