b. Ngb-H64Q has a higher affinity than hemoglobin for both carbon monoxide and oxygen. However, Ngb-H64Q binds to carbon monoxide with a higher affinity than to oxygen.
Explanation:
A study of neuroglobin (Ngb), a hemoglobin-like protein present in the brain, was done at the University of Pittsburgh by a team of researchers. Upon testing the red blood cells of a mouse that contained carbon monoxide, they found that Ngb-H64Q was significantly better at removing CO from hemoglobin than 100-percent oxygen treatment. Hence Ngb-H64Q binds to carbon monoxide with a higher affinity than to oxygen.
<span>The action of Helicase is to create replication forks and replication bubbles. Helicase is the first step in the DNA replication process. Helicase is an enzyme that breaks the hydrogen bond between the parental DNA to free the DNA double helix. The area where it unwinds is called as replication fork.</span>
