George Beadle and Edward Taturn provided clear evidence that genes specified the structure for enzymes in a series of experiment: on the bacterium Pneumococcus. fungus Neurospora fruit fly Drosophila. bacteriophage T4 ciliate Paramecium. DNA was identified as the genetic material in experiments done by Mendel. Beadle and Tatum. Avery, MacLeod, and McCarty, Watson and Crick, Singer and Nicholson. The enzyme that synthesizes DNA using RNA templates is called ________________. In recombinant DNA methods, the term vector can refer to the enzyme that cuts DNA into restriction fragments the sticky end of a DNA fragment a SNP marker a plasmid used to transfer DNA into a living cell a DNA probe used to identify a particular gene

Solution

Answers :

Question number 6 : The correct answer is B (fungus Neurospora crassa)

Explanation : Fungi such as neurospora crassa and yeast have been extensively used as model organisms to study genetic mutations, cell cycle regulation, chromatin modification etc., Beadle and Tatum proposed one gene – one enzyme hypothesis while studying the genetic mutations in the mold Neurospora crassa, which says that each genes acts through production of enzymes, with each gene is responsible for producing a single enzyme that in turn affects a single step in a metabolic pathway
