If the DNA polymerase did nothing special when a mispairing occurred between an incoming deoxyribonucleoside triphosphate and the DNA template, the wrong nucleotide would often be incorporated into the new DNA chain, producing frequent mutations. The high fidelity of DNA replication, however, depends not only on complementary base-pairing but also on several “proofreading” mechanisms that act sequentially to correct any initial mispairing that might have occurred.
Answer: Camels adapt by having a hump and having the ability to store water and food in their hump so they will survive in the desert.

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:
After a cell was treated with a certain chemical, the ribosomes stopped functioning. The cell activity immediately affected by this change in ribosome function is protein synthesis.
Explanation:
The basic structural units of all living things are known as cells. Inside the cells, specialized structures called ribosomes are present, which synthesize proteins. The protein synthesis in a eukaryotic cell consists of two processes, transcription and translation.
The transcription process takes place in nucleus, where the information from a DNA strand is copied into a single stranded messenger RNA (mRNA) molecule using RNA polymerase enzyme. During the ending of transcription, the completed mRNA strand detaches from DNA and exits the nucleus and goes into a ribosome in the cytoplasm. In the ribosome, translation occurs where the genetic code in mRNA is read and protein is synthesized. These proteins are used by cells to perform important functions such as repairing cellular damage, maintain cellular structure, create hormones, cell division etc.
