Whatisbiotechnology.org Website Review

whatisbiotechnology is a content-led community that brings together the stories about the sciences, people and places that have enabled. biotechnology to transform medicine and the world we live in today. we are pleased to publish some reflections from women about what they see as the most important change for women in the life sciences and healthcare sector in recent years. click here to see their comments and contribute your own reflections contributions of women in the biomedical sciences. click here to find out more about this project to see a timeline of initiatives implemented to promote gender equality in the biomedical sciences the following events took place on this day (20th december) in years past: petri was a microbiologist who is credited with inventing the petri dish, a shallow glas* cylinder used to culture cells and bacteria. this he developed in the late 1870s while working as an as*istant to robert koch. petri developed the dish to help culture bacteria on agar plates. he subsequently developed the technique of agar culture to clone bacterial colonies derived from single cells. his work helped improve the process of identifying bacteria responsible for disease. sciences: bacteriology.. the polymerase chain reaction (pcr) technique was published (1985) the pcr technique enabled the amplification of small fragments of dna on a large scale. it was published in rk saiki et al, 'enzymatic amplification of beta-globin genomic sequences and restriction site an*lysis for diagnosis of sickle cell anemia', science, 230 (1985), visit our science section to explore some of the most important sciences behind biotechnology and medicine including: pcr replicate dna. the first step in pcr, known as denaturing, involves heating a dna sample to separate its two strands. once separated the two strands are used as templates to synthesise two new dna strands. this is done with the help of an enzyme called taq polymerase. once made, the newly synthesised molecules are used as templates to generate two more copies of dna. the two basic steps involved in pcr,
