Workers in Dr. Garcia's lab first obtain tumor cells from patients with cancer. They then remove the DNA from the tumor cell nuclei and use enzymes to segment the DNA strands into sections. Finally, they insert the DNA sections in which they are interested into "host" bacteria cells, where the DNA can be reproduced for later use. Dr. Garcia's lab is engaged in work involving:
A) behavior genetics
B) recombinant technology
C) cryogenics
D) autosomal transmission

Question

As defined in the textbook, recombinant DNA technology refers to an assortment of highly sophisticated procedures in which DNA is extracted from cell nuclei and cut into segments; the resulting fragments are then joined to self-replicating elements, in essence forming functional gene clones. These are then placed in host bacterial cells to be maintained and cultured.
