Details of the polymerase chain reaction are given in a previous publication.

The polymerase chain reaction makes sense of that tape.

The test developed at Oxford is based on a technique known as polymerase chain reaction.

The polymerase chain reaction, which we were discussing earlier, is actually very simple.

The polymerase chain reaction is not quite infinitely powerful or infallible.

Both teams used an extremely sensitive and powerful research method called polymerase chain reaction developed in recent years.

The new test, developed by Cetus, uses a procedure called a polymerase chain reaction.

With the use of the polymerase chain reaction additional species have been and are still being identified that infect humans.

There are other methods for amplification besides polymerase chain reaction.

There the chase paused until a technique called the polymerase chain reaction came along.
