Dion and Ethan
We worked together to finish this project. (teamwork) -
Gregor Mendel
Gregor Mendel discovered the fundamental laws of inheritance. He deduced that genes come in pairs and are inherited as distinct units, one from each parent. (genetics) -
Friedrich Miescher
Was the first researcher to identify DNA as a distinct molecule and to isolate and identify nucleic acid. (genetics) -
Thomas Hunt Morgan
Thomas Morgan Hunt was the first person to definitively link the inheritance of a specific trait with a particular chromosome. He was able to confirm the chromosome theory. (genetics) -
Alfred Sturtevant
Alfred Sturtevant constructed the first genetic map of a chromosome. (genetics) -
Frederick Griffith
Frederick Griffith was the first experimenter suggesting that bacteria are capable of transferring genetic information through a process known as transformation. (bacteria) -
Harriet Creighton and Barbara McClintock
These two discovered that the recombination of genes linked on a chromosome requires the physical exchange of segments of the chromosomes with its homologous partner. (genetics) -
Oswald Avery
Oswald Avery is best known for the experiment that isolated DNA as the material of which genes and chromosomes are made and it can be altered through transformation. (genetics) -
Erwin Chargaff
Erwin Chargaff proposed three main rules known as Chargaff's Rules about DNA. The first rule was adenine and thymine residues are equal. Second rule was guanine and cytosine residues are equal. And the third rule is that purines and pyrimidines are equal. (genetics) -
Rosalind Franklin
Rosalind Franklin used x-ray diffraction in order to discover two forms of DNA, a dry "A" form and a wet "B" form. (genetics) -
Al Hershey and Martha Chase
this dynamic duo discovered that genetic material is found in DNA prior to that discovery, most scientists believed that genetic material was found in proteins due to their diversity and prevalence in cells. (genetics) -
James Watson and Frances Crick
In 1953 they determined the double-helix structure of DNA, which is the molecule containing human genes. (genetics) -
Meselson and Stahl
Conducted experiment which supported the hypothesis that DNA replication was semiconservative. -
Joe Hin Tjio
Joe Hin Tjio dispelled a 50 year old held belief that the number of chromosomes in the human cell was 48, when we established the majority of human cells contain 46 chromosomes, arranged in 23 pairs. (genetics) -
Herb Boyer
Herb Boyer discovered a method to coax bacteria into producing foreign proteins, thereby jump starting the field of genetic engineering. (biotechnology) -
Alec Jefferys
Alec Jefferys developed genetic techniques for DNA fingerprinting and DNA profiling which are both now used worldwide in forensic sciences. (genetics) -
J. Craig Venter
J. Craig Venter is the first person to sequence the human genome and the first to transfect a cell with a synthetic genome. (biotechnology) -
Ian Wilmut
Ian Wilmut was the first to use nuclear transfer of differentiated adult cells to generate a mammalian clone, which was a sheep named Dolly. (biotechnology)
