The answer is restriction enzymes. These staggered ends are important in recombination of DNA since they allow DNA strands with complementary sticky ends to be easily joined into one piece by DNA ligase. Other restriction enzymes produce blunt ends. These are harder to join by DNA ligase. An example of a restriction ezyme if EcoRI
The type of chromosomal mutation that occurs here is an example of a deletion mutation. Specific genetic data, or DNA is removed and the remaining portions of chromosomal information have rejoined.
The answer to this question would be: vertebrae
In vertebrae fracture, traction is important to assure immobilization of the vertebrae. Movement can cause the fragment of bone in the fracture damaging the neural tissue in the vertebrae.
To ensure no movement in the neck, metal tongs can be put on the skull. The tongs will help fixate the skull with the shoulder.
