understanding microbes

through 20th cent scientists built on earlier research and findings. Developed techniques used by Pasteur and Koch to discover further microbes causing diseases. Created vaccines to stop people getting the diseases

1 of 18

Improved knowledge of what helped what?

knowledge of how microbes caused disease which led to cures known as magic bullets

measles vaccination

9 of 18

1998

MMR (measles, mumps and rubella) vaccination

10 of 18

discovery of DNA structure and work of human genome project led to steps such as

improved vaccinations, better insulin for diabetes, new techniques for skin grafts, better understanding of things such as downs syndrome, better undertsanding of developments such as cancer, stem cells able to grow into different cells discovery

continuing research means what?

faulty genes could be corrected and genetic diseases could be prevented in the future

Understanding genetics

another break lol

13 of 18

during 19th century

Mendel showed how human characteristics could be passed down between generations

14 of 18

20th century

new technology (electron microscopes, X-rays) let scientists analyse human cells in more detail. Found that every cell in body contains DNA- codes controlling the genes of each person

15 of 18

Watson and Crick 1

worked together on how genetic codes of DNA fitted together

16 of 18

Watson and Crick 2

analysed X-ray crystallography by Maurice Wilkins and Rosalind Franklin at kings college hospital eventually worked out double helix structure of DNA (1953)

17 of 18

1990

Watson led the human genome project and started identifying and mapping every gene in human DNA
