Johann set out to research the key components of white blood cells , part of our body’s immune system. The main source of these cells was pus-coated bandages collected from a nearby medical clinic.]]> 2018-04-03 16:10:29 UTC https://padlet.com/1013168/4vv35avp5414/wish/248188095 1013168 https://padlet.com/1013168/4vv35avp5414/wish/248533892 It is a common misconception that James Watson and Francis Crick discovered DNA in the 1950s. In reality, DNA was discovered decades before. It was by following the work of the pioneers before them that James and Francis were able to come to their ground-breaking conclusion about the structure of DNA in 1953.]]> 2018-04-04 15:09:43 UTC https://padlet.com/1013168/4vv35avp5414/wish/248533892 1013168 https://padlet.com/1013168/4vv35avp5414/wish/248542653 Friedrich Mieschefer's Lab was found in 1969 to offer highly qualified junior scientists in the area of biology an opportunity to establish independent research groups and pursue their own line of research within a five-year period . ]]> 2018-04-04 15:26:28 UTC https://padlet.com/1013168/4vv35avp5414/wish/248542653 1013168 https://padlet.com/1013168/4vv35avp5414/wish/248546134 DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what determines DNA's instructions, or genetic code]]> 2018-04-04 15:33:49 UTC https://padlet.com/1013168/4vv35avp5414/wish/248546134 1013168 https://padlet.com/1013168/4vv35avp5414/wish/248908957 Most genetic ancestry tests involve the analysis of small snippets of DNA passed down only through the mother, or only through the father. These tests can identify related individuals who share a common maternal or paternal ancestor, and even where in the world people with your genetic signature live today.]]> 2018-04-05 15:06:28 UTC https://padlet.com/1013168/4vv35avp5414/wish/248908957
