What is true of reverse genetics

  1. Gene therapy

  2. Gene replacement

  3. Identification of gene from map position

  4. Deletion of genes and studying the effect
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Reverse genetics is a method that is used to help understand the function of a gene by analyzing the phenotypic effects of specific engineered gene sequences. Reverse genetics usually proceeds in the opposite direction of so-called forward genetic screens of classical genetics. The goal in reverse genetics is Identification of gene from map position.

So, the correct answer is 'Identification of gene from map position.'

All the following statements about Stanley Cohen and Herbert Boyer are correct but one is wrong. Which one is wrong?

  1. They discovered recombinant DNA ( rDNA) technology which marked the birth of modern biotechnology.

  2. They first produced a healthy sheep clone, a Finn Dorset lamb, Dolly, from the differentiated adult mammary cells.

  3. They invented genetic engineering by combining a piece of foreign DNA containing a gene from a bacterium with a bacterial (E. coli) plasmid using the enzyme restriction endonuclease.

  4. They isolated the antibiotic resistance gene by cutting out a piece of DNA from a plasmid which was responsible for conferring antibiotic resistance.
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

  • The recombinant DNA technology by which DNA fragments from different organisms are joined together to produce new genetic combinations was discovered by Stanley Cohen and Herbert Boyer. 
They used restriction endonucleases to digest a plasmid from E. coli and a foreign DNA segment and ligated them to produce a recombinant DNA.
They discovered antibiotic resistance gene from a piece of DNA that was conferring resistance to the transformed cells to grow in presence of that antibiotic.
  • Dolly, a Finn Dorset lamb, was produced by gene cloning by Ian Wilmut and his co-workers.
Hence Stanley Cohen and Herbert Boyer are not associated with the discovery of Finn Dorset lamb Dolly.
So, the correct answer is 'They first produced, healthy sheep clone, a Finn Dorset lamb, Dolly, from the differentiated adult mammary cells'.

Out of the following, which is not related to biotechnology?

  1. Synthesis of a gene

  2. Correction of a gene

  3. Alternation of gene

  4. Transfer of a gene from parent to off spring
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Biotechnology deals with the techniques of using live microorganisms, plant or animal cells or their components or enzymes from organisms to produce products and processes useful to human beings. It includes DNA manipulation, gene manipulation, recombinant DNA technology, and Genetic Engineering. Synthesis of genes, correction of genes, alteration of genes are included in Genetic Engineering. 

Transfer of gene from parent to offspring is a normal way of heredity. All offsprings inherit some characters from their parents as a result of fertilization. 

Thus the correct option is 'Transfer of a gene from parent to off spring'.
