What limitation of traditional hybridization procedures used in plant and animal breeding can be overcome by recombinant DNA procedures?

Which of the given statements is correct in the context of visualizing DNA molecules separated by agarose gel electrophoresis?

Which of the following is not required in the preparation of a recombinant DNA molecule?

A reporter enzyme used in biotechnology includes all the following except:
1. Green Fluorescent Protein
2. Luciferase
3. Beta Galactosidase
4. Chloramphenicol acetyl transferase

A donor DNA and plasmid vector DNA of E. coli are cut by EcoRI. The plasmid contains genes for resistance to ampicillin and tetracycline. The ECoRI recognition sequence lies within the gene for tetracycline resistance. Ligase is used, and the recombinant DNA is produced. The plasmids are transferred to E.coli with the help of electroporation. Samples of the bacterial colonies are then grown in four different media: nutrient medium plus ampicillin, nutrient medium plus tetracycline, nutrient medium plus ampicillin and tetracycline, and nutrient medium without antibiotics. Non-recombinant transformants will grow on:

Which of the following is not a plasmid?

Which of the following can be used to induce competence for getting a bacterial cell transformed during rDNA procedures?

If any protein-encoding gene is expressed in a heterologous host, the protein formed is called:
