Question

question 3 (1 point)
from reviewing figure 10.1 on page 246, a circular section of dna from a bacterial
cell called a ____ is used in recombinant dna technology. the gene of interest
from another cell is inserted into this structure.
a) plasmid
b) restriction enzyme
c) desired clone
d) transgenic organism

Explanation:

In recombinant DNA technology, a plasmid is a small, circular DNA molecule that can replicate independently of the chromosomal DNA in bacteria. It is often used as a vector to insert foreign DNA (such as a gene of interest from another cell) into a host cell. Restriction enzymes are used to cut DNA, not as the structure into which DNA is inserted. A desired clone is the result of successful gene insertion and replication, not the initial structure. A transgenic organism contains foreign DNA integrated into its genome, which is a later stage after the gene has been inserted into a plasmid and then into the organism's cells.

Answer:

A. plasmid
