The correct answer is "Support the head in the position you find it. Do not try to align it." This is because in a patient with a possible head, neck, or spinal injury, mobilization or moving the the head can potentiate more damage; especially to the cervical vertebra and cervical spine, producing dire consequences such as paralysis and paresthesias. The best thing to do is to support the head and attach a cervical collar, if possible.
Supercoiling is an important property of DNA tertiary structure that affects essential processes such as replication and transcription. Negative supercoiling is very important. Negative supercoiling causes unwinding of DNA and it makes the DNA strand ready for biological processes such as replication and transcription. Negative supercoiling is introduced in a DNA with the help of enzyme topoisomerase enzymes I and II. In bacteria topoisomerase enzyme II is called gyrase.
