If replication of DNA does not maintain accuracy there will be mutations. Not all mutations are bad.
In fracture patient, splinting is beneficial as it could prevent damage to the vascular and nerve tissue by immobilizing it. But splinting is also dangerous. To immobilize the extremity, splint needs to be put with enough force. This force often can cause damage as it could block the arteries that run in the extremity, causing ischemia.
It is important to do the assessment before and after splint to make sure the splint doesn't cause damage to the patient.
Answer:
The bacterial DNA gets degraded at step 3 of the viral lytic cycle.
Explanation:
Viruses are organisms that are incapable of replicating on their own, hence, they require a living host which they infect and use its replicational ability to reproduce theirselves. The infection cycle of this virus is regarded as its replication cycle. Viruses employ either the LYTIC or LYSOGENIC cycle for infection.
The lytic cycle involves killing of their host cell at the end of the cycle. Generally, the cycle starts with the attachment of my the virus to the cell membrane of its host using specific receptor sites (step 1). It then penetrates the host cell as seen in step 2.
After penetration, the virus then secretes certain degrading enzymes called ENDONUCLEASES that degrades the bacterial DNA. After which the virus uses the replicational and gene expressing ability of the host to transcibe its genetic material and replicate itself. This process called SYNTHESIS occurs in step 3.
Hence, the yellow ring in the image that represents bacterial DNA disappears in step 3 (synthesis stage) because it gets degraded by viral digesting enzymes.
Would need a strong background in biology and ... B. Chemistry
I thing B is the right answer
