Correct Answer
D. Glenn T. SeaborgExplanation
Glenn Theodore Seaborg was an American scientist who won the 1951 Nobel Prize in Chemistry for "discoveries in the chemistry of the transuranium elements," contributed to the discovery and isolation of ten elements, developed the actinoids concept and was the first to propose the actinoids series which led to the current arrangement of the Periodic Table of the Elements.
Seaborg was the principal or co-discoverer of ten elements: plutonium, americium, curium, berkelium, californium, einsteinium, fermium, mendelevium, nobelium and element 106, which was named seaborgium in his honor while he was still living. He also developed more than 100 atomic isotopes, and is credited with important contributions to the separation of the isotope of uranium used in the atomic bomb at Hiroshima.Rate this question:

Which American scientist entered graduate school intending to study ecology, but soon switched his focus to genetics and cytology and later on won a Nobel Prize for discovering the role of genes in regulating biochemical events in cells.
- A.
Franklin D. Keim
- B.
George W. Beadle
- C.
Rollins A. Emerson
- D.
Barbara McClintock
Correct Answer
B. George W. BeadleExplanation
George Wells Beadle was an American scientist in the field of genetics, and Nobel Prize in Physiology or Medicine Nobel laureate who with Edward Lawrie Tatum discovered the role of genes in regulating biochemical events within cells.
Beadle and Tatum's key experiments involved exposing the bread mold Neurospora crassa to x-rays, causing mutations. In a series of experiments, they showed that these mutations caused changes in specific enzymes involved in metabolic pathways. These experiments led them to propose a direct link between genes and enzymatic reactions, known as the "one gene, one enzyme" hypothesis.Rate this question:

- A.
Joseph L. Gay-Lussac
- B.
Antoine-Laurent de Lavoisier
- C.
Stanislao Cannizarro
- D.
JĹ‘ns J. Berzelius
Correct Answer
B. Antoine-Laurent de LavoisierExplanation
Antoine-Laurent de Lavoisier, the father of modern chemistry, was a French noble prominent in the histories of chemistry and biology. He stated the first version of the law of conservation of mass, recognized and named oxygen (1778) and hydrogen (1783), abolished the phlogiston theory, helped construct the metric system, wrote the first extensive list of elements, and helped to reform chemical nomenclature.
As one of twenty-eight French tax collectors and a powerful figure in the unpopular Ferme Générale, Lavoisier was branded a traitor during the Reign of Terror by French Revolutionists in 1794. Lavoisier had also intervened on behalf of a number of foreign-born scientists including mathematician Joseph Louis Lagrange, granting them exception to a mandate stripping all foreigners of possessions and freedom. Lavoisier was tried, convicted, and guillotined on 8 May in Paris, at the age of 50.Rate this question:

- A.
Alfred Hershey
- B.
Raymond Gosling
- C.
Maurice H. F. Wilkins
- D.
Rosalind Franklin
Correct Answer
D. Rosalind FranklinExplanation
Rosalind Elsie Franklin was an English biophysicist and X-ray crystallographer who made important contributions to the understanding of the fine molecular structures of DNA, RNA, viruses, coal and graphite. Franklin is still best known for her work on the X-ray diffraction images of DNA. Her data, according to Francis Crick, were “the data we actually used” to formulate Crick and Watson's 1953 hypothesis regarding the structure of DNA. Furthermore, unpublished drafts of her papers (written as she was arranging to leave the unsupportive research situation at King's College London) show that she had indeed determined the overall B-form of the DNA helix. However, her work was published third, in the series of three DNA Nature articles, led by the paper of Watson and Crick which only vaguely acknowledged her evidence in support of their hypothesis.Rate this question:

Where in the cell are proteins produced?
- A.
Golgi apparatus
- B.
Endoplasmic reticulum
- C.
Peroxisome
- D.
Ribosomes
Correct Answer
D. RibosomesExplanation
The ribosome functions in the expression of the genetic code from nucleic acid into protein, in a process called translation. Ribosomes do this by catalyzing the assembly of individual amino acids into polypeptide chains; this involves binding a messenger RNA and then using this as a template to join together the correct sequence of amino acids. This reaction uses adapters called transfer RNA molecules, which read the sequence of the messenger RNA and are attached to the amino acids.Rate this question:
