For numbers 14-15, refer to the following choices below.

A. Statement is correct H. Statement Il is correct.

C. Statement 1 and 11 are both correct.

D. Statement 1 and I are both incorrect.

14 1-Since ancient time the practice af genetic engineering had begun.

II-Artificial selection is done to indirectly manipulate genes focusing on the physical traits among organisma.

151-Vectors help in Recombinant DNA technology by carrying and integrating the desired gene usually plasmids and

bacteriophages

11-Host organism is used to propagate the recombinant DNA.​
