Answer:
Enzymes lower the activation energy that is needed, making reactions happen at a lower temperature that they could without the enzyme. This speeds up the rate of reaction.
Explanation:
Answer:
c) Nucleoside reverse transcriptase inhibitors may interfere with DNA replication by the host, not just by the virus.
Explanation:
A drug that targets the structures or processes specific to the pathogen or microbe has fewer side effects than the drugs that target the more general structures and processes exhibited by both the pathogen and host cells.
According to the given information, the nucleoside reverse transcriptase inhibitors resemble thymine and terminate the process of DNA replication. Thymine base is also one of the nitrogenous bases present in the human cells and other organisms. Therefore, the nucleoside reverse transcriptase inhibitors would terminate the process of DNA replication in both the virus and the host organism.
On the other hand, the non-nucleoside reverse transcriptase inhibitors specifically target the reverse transcriptase enzyme that is not present in host organisms. Therefore, the non-nucleoside reverse transcriptase inhibitors have fewer side effects than the nucleoside reverse transcriptase inhibitors.
Answer:
Flowers
Explanation:
All angiosperms produce flowers.
restricted endonucleases are used to cut DNA into smaller fragments
Answer: False
Explanation:
Protozoans are not the organism that fix nitrogen for the plants. The organism that fix nitrogen to convert it into a form which can be used by plants are known as diazotrophs.
These are bacteria and archae that fix nitrogen gas found in the atmosphere into more usable form such as ammonia.
These organism can grow without any external source of fixed nitrogen. Example: Rhizobia and azospirillium.
