Question

Recombinant proteins, often seen in the news, are ________?

• A. proteins synthesised in animal models
• B. natural proteins found in bacteria
• C. proteins synthesised in mutated cell lines
• D. proteins synthesised by transgene in host cell by rDNA technology

Answer 1

Answer:

D. proteins synthesised by transgene in host cell by rDNA technology

Recombinant proteins are proteins synthesized by a transgene in a host cell using recombinant DNA (rDNA) technology. This process involves inserting a gene encoding the desired protein into a host organism's genome, enabling the host to produce that protein Recombinant proteins are polypeptides produced from cloned genes by recombinant DNA techniques, generally in a heterologous expression system. The process begins with DNA fragments containing the gene of interest.
