SSC MCQ Question Ans. Biotechnology

They saw that all the genes of a living being are not good for that living being. The scientists began to investigate, how the gene can be transferred from one cell to another cell without fertilization, how the harmful gene can be deleted and the good or suitable gene can be inserted in that place. Herbert Boyer and Stanley Cohen, the researchers of California University, in 1973, at first were successful in inserting gene artificially, without fertilization. In the history of biology, it was an unimaginable event. It instituted a new branch of biology called biotechnology or genetic engineering. We will discuss chromosome, gene, DNA and RNA before discussing biotechnology. We have got an overall knowledge about chromosome, gene, DNA and RNA in class Eight. We shall know it in detail in this chapter.
