The Basis of DNA Technology

Question 13 • Biology_A_IC

Which best describes the process of making recombinant DNA?

Answer
A
The isolated DNA is inserted into a mechanical vector for cloning.
B
The isolated genes are placed into a vector.
C
The sticky ends of fragmented DNA are joined with vector DNA.
D
The isolated genes are joined by using restriction enzymes.

Explanation

Recombinant DNA is made by joining DNA fragments from different sources. Restriction enzymes cut the DNA and vector to create matching sticky ends, which can pair and then be sealed together. Thus, “the sticky ends of fragmented DNA are joined with vector DNA” best describes the process; restriction enzymes cut DNA rather than join it.
