Restriction enzymes cut the DNA (deoxyribonucleic acid) molecules at specific restriction sites on both the strands and produce
sticky ends or blunt ends.
If the restriction enzymes make staggered cuts of the two strands of DNA, then fragments having sticky ends will be formed.
In table 8.1, BamHI, EcoRI, HindII,I and HinfI will produce restriction fragments with sticky ends.

Genetic screening can identify the infection of viruses even before the patient shows any sign of infection.
The cancer inducing virus, Human T-lymphotropic virus 1 or HTLV-1 inserts itself into the human chromosome. There it remains.
Thus that particular gene in the human chromosome gets mutated. The mutated gene can be identified by using genetic screening.
The scientists use DNA or Deoxyribonucleic acid microarrays to screen patients for such mutated genes.
DNA microarray consists of single-stranded DNA immobilized on a substrate.

A thermocycler is a device that automatically performs Polymerase Chain Reaction (PCR) by continuously cycling through the
three temperature regimes.
The Deoxyribonucleic Acid (DNA) polymerase derived from hyperthermophilic bacteria, such as, Taq DNA polymerase remains
stable at all the three temperatures used in PCR. It is resistant to temperature fluctuations as well as to the high temperature.
