What gets asked: 16 concepts
Every question in the bank is tagged to one of these, so practice can target the exact idea you keep missing.
Sample questions
A circular plasmid vector is shown with restriction sites for EcoRI and HindIII, and an ampicillin resistance gene (ampR) and tetracycline resistance gene (tetR). If a foreign DNA fragment is inserted into the EcoRI site within the tetR gene, what will be the expected outcome regarding antibiotic resistance of the transformed bacteria?
Assertion (A): Genetic engineering allows the introduction of only one or a desired set of genes into a target organism. Reason (R): Unlike traditional hybridisation, recombinant DNA technology avoids the transfer of undesirable genes along with the desired ones. Select the correct option:
Observe the diagram below and identify the labeled part that helps in the separation of DNA fragments. (Diagram Description: A gel electrophoresis apparatus is shown. It consists of a gel matrix, wells at one end, and electrodes at both ends. DNA samples are loaded into the wells. 'A' points to the wells where DNA samples are loaded. 'B' points to the positive electrode (anode) at the bottom end of the gel. 'C' points to the gel matrix. 'D' points to the negative electrode (cathode) near the wells.)
