In gene gun method used to introduce alien DNA into host cells, microparticles of ________ metal are used.
Zinc
Tungsten or gold
Silver
Copper
Tungsten or gold microparticles are commonly used in the gene gun method for gene transfer. The microparticles are coated with the foreign DNA of interest and are then propelled into the target cells using a biolistic device (gene gun). The high velocity of the microparticles enables them to penetrate the cell membranes and deliver the foreign DNA into the host cells, allowing for genetic transformation or transfection.
Therefore, The correct option is (B): Tungsten or gold
During the purification process for recombinant DNA technology, addition of chilled ethanol precipitates out
Upon exposure to UV radiation, DNA stained with ethidium bromide will show
Biotechnology is a vast field of biology that involves the creation, production, and modification of useful products for human welfare using both the technology and the execution of living organisms and their components. An agricultural engineer, Karoly Ereky, coined the word "biotechnology" in 1919, achieving him the title of "Father of Biotechnology."
Among many, the two core techniques that entitled the birth of modern biotechnology are :
