Process and analyse information from secondary sources to explain a modern example of ‘natural’ selection. (Structural, Physiological, Behaviour)
Some organisms, such as bacteria and insects, produce large numbers of offspring. Amongst large numbers of bacteria offspring, some individuals may carry genes that give them resistance to antibiotics. These individuals are then able to survive and reproduce with reduced competition from other members of the same species. Each generation will produce a higher percentage of individuals containing the resistant genes.
A modern example of ‘natural’ selection, is the development of microorganisms physiologically (including, bacteria, viruses, fungi and parasites). These organisms have been able to develop a resistance to antimicrobial drugs (antibiotics, antifungals and antivirals) known as AMR (antimicrobial resistance). This leads to prevention method’s efficiency decreasing, therefore standard treatments become ineffective and infections persist, increasing the risk of …show more content…
The four people in this finding conducted studies in two different locations. Rosalind Franklin and Maurice Wilkins studied at King's College London whereas, James Watson and Francis Crick studied at Cambridge University. Rosalind Franklin was a woman working in a field that was male dominated however it is believe she didn't get equal recognition for her contributions. Her work on X-ray diffraction showed that DNA had the characteristics of a helix. However prior to gathering more results Wilkins had already shown her research to Watson and Crick unknowingly. This allowed them to begin development on their model of the said helix. Franklin later died from cancer in 1958 at the age of 37. Watson, Crick and Wilkins later received the Nobel Prize for their work in 1962 on the research of DNA
