Chapter 13, Problem 15QP
Summary Introduction
Introduction: A process of molecular biology which is responsible for the production of various copies of a particular segment of DNA is called “polymerase chain reaction (PCR).” Using the technique of PCR, a single segment of DNA can be amplified to produce sufficient number of copies of that particular segment.

(a) Restriction sites are usually ______.
Recombinant DNA Technology
Restriction enzymes
Ligase
Palindromic sequences
(b) Involves joining a donor DNA fragment of interest to a vector
Recombinant DNA Technology
Restriction enzymes
Ligase
Palindromic sequences
Restriction enzymes and DNA ligase play essential roles in DNA cloning. How is it that a bacterium that produces a restriction enzyme does not cut its own DNA?
PCR is a very useful method in biotechnology because it does not require the 6 or more different key proteins/enzymes required for DNA replication in living cells. Explain how and why this technique only requires 1 enzyme to make lots of DNA.

- Would it be possible to use human polymerase for the PCR reaction? a. No, because human polymerase does not have the ability to withstand the high temperatures required for the PCR reaction to occur. b. No, because human polymerase cannot be extracted from cells to use in a lab setting. c. Yes, because we are using human DNA as the template DNA. d.
