Answer:
"Viral reverse transcriptase to make a DNA copy that is integrated into the host genome and then host RNA polymerase transcribes it is a true statement.
Explanation:
The virus is an infectious agent which is not considered living either considered non- living. The virus particles contain the genetic material that determines the trait of a virus in the form of either DNA or RNA.
The virus which contains the RNA replicates themselves by fist converting their RNA into DNA by reverse transcriptase enzyme. Once the DNA is made, the DNA is incorporated in the genome of the host and the machinery of the host performs the replication, transcription and translation.
Thus, the selected option is true.
Answer: The bacteria uses the oxygen present in the mouth.
Explanation:
The plaque that is formed in the teeth is a highly anaerobic bacteria but it can sustain in the environment rich in oxygen. The oxygen is used by the bacteria and there is a absence of oxygen in the teeth.
It is formed in between the teeth which needs oxygen to survive and if remains for tooth for a longer period of time then it began to grow without oxygen.
It basically uses the oxygen available in the mouth and makes the condition anaerobic.
