Which type of cell can be useful for producing a protein product from an introduced gene?

Answer and explanation

Correct answer: मेजबान कोशिका

In recombinant DNA technology, a host cell receives a vector carrying the desired foreign gene. If the gene is placed under suitable regulatory control and the host has the required cellular machinery, the gene can be expressed and its protein product can be produced. Bacteria, yeast and cultured mammalian cells are examples of hosts used for different proteins. Option A is correct because a living host cell can replicate DNA, transcribe the gene and translate its messenger RNA. Paper and glass are not living cells, and a cell completely lacking DNA cannot normally support the necessary genetic and regulatory functions.
