The European Federation of Biotechnology [EFB] defines biotechnology as:
1. The use of living cells and bacteria in industrial and scientific processes.
2. The integration of natural sciences and organisms, cells, parts thereof, and molecular analogues for products and services.
3. The use of biology to solve problems and make useful products.
4. The use of biology to develop new products, methods and organisms intended to improve human health and society.

The palindrome in DNA is a sequence of base pairs:
1. that reads same on the two strands when orientation of reading is kept the same.
2. that reads same on the two strands when orientation of reading is 5’ to 3’ on one end and 3’ to 5’ on the other.
3. that are complementary on the two strands when orientation of reading is kept the same. 
4. that are complementary on the two strands when orientation of reading is 5’ to 3’ on one end and 3’ to 5’ on the other.

Identify the incorrect statement regarding restriction endonucleases:

1. They mostly cut dsDNA at specific base sequences.
2. They are produced by bacterial cells as a mechanism of self-defence.
3. They digest DNA by removing nucleotides from a free 3' end.
4. They often generate short single-stranded sequences at the ends of the resultant fragments.
