Answer:
Yes, there is a need to assure the client that this is a normal reaction.
Explanation:
In the given case, it is the duty of a nurse to assure the patient that swelling takes place while performing intradermal vaccination. As with the administration of disease-specific antigens, the injected area inflames that generally takes place due to the development of antibodies against the presented antigens.
Thus, both the patient and the nurse need to be calm in such a situation and should leave the swelling open so that it can get heal by itself. In case, if one applies ice packs or rubs the affected area, it can enhance the condition and may result in more issues.
Answer:
<em> A nick is created between G and A in GAATTC when using Eco R1 site while a nick is generated between G and G in GGATCC when Bam H1 is used. The difference in the nicks created is the main reason you observe two bands when you digest the circular plasmid with a mixture of both</em>
Explanation:
Circular plasmid containing : 9 kb of DNA
Eco R1 and Bam H1 are known as restriction sites in DNA ( i.e. special sequences found in a DNA ) hence they can be specifically cleaved by the restriction enzymes enabling the insertion of a gene. that is why you will get a same result when you digest the Plasmid with either Eco R1 or Bam H1
<em>but A nick is created between G and A in GAATTC when using Eco R1 site while a nick is generated between G and G in GGATCC when Bam H1 is used. The difference in the nicks created is the main reason you observe two bands when you digest the circular plasmid with a mixture of both</em>
The particles vibrate but they are tight together so they don’t move past each other
