for number 14-15, refer to the following choices below.
a.) statement 1 is correct
b.) statement 2 is correct
c.) statement 1 and 2 are both correct
d.) statement 1 and 2 are both incorrect

14.) 1-since ancient time the practice of genetic engineering had begun.
2-artificial selection is done to directly manipulate genes focusing on the physical traits among organisms.

15.) 1-enzymes help in recombinant dna technology by carrying and integrating the desired gene usually classmates and bacteriophages.
2-host organism are used to propagate the recombinant dna. ​
