Question

Study the following statements regarding recombinant DNA technology and select the correct one.

विकल्प

• Taq polymerase extends the primers using the nucleotides provided in the reaction.

• Antibiotic resistance genes are considered desirable genes in recombinant DNA technology.

• DNA fragments are separated according to their charge only in agarose gel electrophoresis.

• Downstream processing is one of the steps of the polymerase chain reaction.

Answer 1

Taq polymerase extends the primers using the nucleotides provided in the reaction.

Explanation:

Other assertions can be modified because antibiotic-resistance genes are selected markers. Desirable genes are those that are inserted into vectors in order to produce a desired protein output. In agarose gel electrophoresis, DNA fragments are sorted based on their charge and size. Downstream processing is a recombinant DNA technology stage that comprises separation and purification.
