5 Questions
What is the function of restriction endonucleases?
The function of restriction endonucleases is to cut invading viral DNA.
How do Type II restriction endonucleases recognize DNA sequences?
Type II restriction endonucleases recognize perfectly palindromic sequences in DNA.
What type of ends can restriction endonucleases produce when cutting DNA?
Restriction endonucleases can produce either sticky ends or blunt ends with no overhang.
What is the unique base sequence cutter for every 256 base pairs?
The unique 4 base sequence cutter occurs every 256 base pairs.
What is the purpose of DNA ligase in recombinant DNA technology?
DNA ligase is used to join adjacent DNA fragments during the recombination process.
Test your knowledge on Restriction Endonucleases, a class of enzymes derived from bacteria that play a protective role by cutting invading viral DNA. Learn about their recognition of palindromic sequences, binding as dimers, and their ability to produce sticky or blunt ends.
