Choose all of the following that are true of the Hersey-Chase Blender Experiment:A. It utilized radioactively labelled phages in which the DNA was labelled with 35S and the protein coat was labelled with 32PB. It utilized radioactively labelled phages in which the DNA was labelled with 32P and the protein coat was labelled with 35SC. It showed that DNA is composed of Adenine, Guanine, Cytosine, and ThymineD. It offered definitive proof that DNA is the molecule of heredity Solution 5) the answer are (B & C) cell theory was given by two scientists and they were Theodor Schwan & Matthias Schleiden..

It utilized radioactively labelled phages in which the DNA was labelled with 35S and the protein
coat was labelled with 32PB.
It utilized radioactively labelled phages in which the DNA was labelled with 32P and the protein

It offered definitive proof that DNA is the molecule of heredity
Solution
5) the answer are (B & C) cell theory was given by two scientists and they were Theodor Schwan
& Matthias Schleiden.. They both stated that it consists of double layer phospholipids
membrane..
4) Watson and Crick discovered DNA & Rosalind Franklin determined the structure of the
dsDNA by X-rays crystallography..!! (A& B)
2) Hershey and Chase experiment they radio labeled the DNA with 32P and protein with 32S as
DNA contains Phosphorus and protein contains Sulphur.. It offered the definite proof that DNA
is passed to one generation to other as 32P was observed in progeny..(B&D)
3) the answer is (c & D) . He gave the one enzymes one gene hypothesis.. He took those strains
which are Metabolic disorder..!!
1) Thomas Morgan demonstrated Sex linkage..!!!
