Explanation:
RNA polymerase will keep transcribing until it gets signals to stop. The process of ending transcription is called termination, and it happens once the polymerase transcribes a sequence of DNA known as a terminator.

Answer:
<u><em>The above statement is true.</em></u>
Explanation:
A proto-oncogene can be described as a gene which is normal but if mutation occurs then it can be converted into a cancerous gene. Proto oncogenes have different functions to perform. Some of them act as signals for cell division while others might be involved in the process of apoptosis. A point mutation can be described as a mutation by which just a single nucleotide gets changed. Even a change in the single nucleotide can cause a proto oncogene to convert into an oncogene and cause cancer.
Answer:
A. The bacteria could no longer regenerate the NAD+ needed for glycolysis, so it would stop producing ATP.
Explanation:
According to the given information in this question, Lactobacillus acidophilus is a bacterium species that uses the lactic acid fermentation when there is no oxygen in its cell i.e. under anaerobic conditions. This means that it converts glucose to lactic acid during this anaerobic respiration process.
However, if the lactic acid fermentation pathway were blocked under an anaerobic condition, this means that it will be no longer be able to perform respiration and hence stop production of ATP. This is because the bacteria will no longer regenerate the NAD+ (electron acceptor) needed for glycolysis, so it would stop producing ATP. Note that, all living organisms, whether aerobic or anaerobic, undergo GLYCOLYSIS, which is the first stage of cellular respiration.
