Answer»

Griffith
HERSHEY and Chase
Avery, MacLeod and Mc Carty
Hargobind Khorana

Solution :The final PROOF that DNA is the genetic material came from the experiments of Alfred Hershey and Martha Chase (1952). Griffith 's experiment proved the existance of genetic material while Avery MacLeod and McCarty WORKED to determine the biochemical nature of transforming principle.
Concept Enhancer Hershey and Chase during their experiment , grew viruses in two mediums , one containing `.^(32)P and "other" .^(35)S`, when these were allowed to INFECT bacteria, they observed that viruses containing `.^(32)P` DNA were radioactive while those with`.^(35)S` protein werenot radioactive . Hence , DNA not protein COAT entered bacterial cells from viruses.

Question : The figure shows the restriction enzyme cutting sites (R1-R3) in wild type (n) and mutant (n) gene. If a radioactively labelled probe (that hybridises at a sequence close to R1) is used for detecting the presence of DNA fragments after gel electrophoresis and Southern blotting, which of the following band patterns will yout expect ? Note : L1 : wild type DNA, L2: mutant DNA

Answer»

(a)
(b)
(c)
(d)

Solution :Restriction enzymes recongise the base sequence of PALINDROME sites in DNA duplex and cut is strands. After the CUTTING of DNA by restriction enzymes, fragments of DNA are formed. SEPARATION of DNA fragments according to their SIZE is done by gel electrophoresis. since the probe hybridises close to `R1` it will give 500 kb band for `L1` and 400 kb band for `L2` after gel electrophoresis.
