Under Lesson 1: Names and their Contributions Flashcards
He suggested that
chromosomes are involved with inheritance
Theodor Boveri
The first human gene is
sequenced by whom? It is the gene that causes
cystic fibrosis
Francis Collins and Lapchee Tsui
He discovered the Polymerase Chain Reaction (PCR), enabling lengths of DNA to be multiplied
Kary Mullis
He finds the amounts of adenine and thymine in DNA are about the same, as area the amounts of guanine and cytosine
Erwin Chargaff
He published the investigations into
inheritance of pea plants
Gregor Mendel
These 2 scientists, who worked independently, proposed that certain chromosomes determine sex. They show that a single Y chromosome determines maleness, and two copies of the X chromosome determine femaleness.
- Edmund Beecher Wilson
- Nettie Stevens
Mendel’s work was rediscovered by these three scientists
- Hugo De Vries
- Erich von Tschermack
- Carl Correns
These 3 scientists, who worked independently, sequenced the DNA from virus for the first time?
- Frederick Sanger
- Walter Gilbert
- Allan Maxam
They discover that X-rays can be used to study the molecular structure of simple crystals, such as salt
Sir William Henry Bragg and his son
They used bacteria to show that DNA is the hereditary material
- Oswald Avery
- Colin MacLeod
- Maclyn McCarty
He proved that genes are carried on chromosomes. He also showed that some characteristics are carried on the sex chromosome.
Thomas Hunt Morgan
He discovered ‘transformation’ in bacteria
Frederick Griffith
He observed chromosomes in grasshopper cells
Walter Sutton
He mapped the genes on the fruit fly’s sex chromosomes.
Alfred Henry Sturtevant
He discovered that some diseases might be inherited
Archibald Garrod
He gave the term “genetics”
William Bateson
They proposed that DNA molecule is a double-stranded helix
James Watson and Francis Crick
They analyze mitochondrial DNA in different human races. They declared that humans have a common ancestor who lived 200,000 years ago.
- Rebecca Cann
- Mark Stoneking
- Allan Wilson
He published “The Theory of the Gene”
(Thomas Hunt) Morgan
They work out the genetic code
Marshall Nirenberg and
Heinrich Matthaei
These 2 scientists, who worked independently, suggested that each egg and sperm cell contains only one of each chromosome pair
Sutton and Boveri
He used the term ‘gene’ to describe the carrier of heredity, ‘genotype’ to describe an organism’s genetic make-up, and ‘phenotype’ to describe an organism’s outward appearance.
William Johannsen
