The question is incomplete. The complete question is as follows:
Which characteristics of DNA polymerase I raised doubts that its in vivo function is the synthesis of DNA leading to complete replication?
its composition of a single polypeptide chain
.
deficiency of enzyme in some organisms that are still capable of DNA synthesis
.
requirement of Mg2+ presence in order for the enzyme to work
.
low stability under normal physiological conditions.
Answer:
Deficiency of enzyme in some organisms that are still capable of DNA synthesis
Explanation:
The DNA polymerase I may be defined as the important enzyme that play an important role in the DNA replication of prokaryotes. DNA pol I is the replicating enzyme, DNA repair enzyme and can also acts as the exonuclease.
DNA pol I has been studied invitro and Arthur Korenberg explain the discovery of the DNA pol I. This DNA pol I plays an important role in DNA repair rather than the replication process. This explained invivo by the fact that some in some organisms the deficiency of this enzyme do not halt the process of replication. If the DNA pol I acts as the main replaicating enzyme, the DNA synthesis must be stopped in the organisms that lack DNA synthesis.
Thus, the correct answer is option (2).
The answer is smallet is size.
<h3>What is electrode?</h3>
- Electrode, electric conductor, usually metal, operated as either of the two terminals of an electrically operating medium; it conducts current into and out of the medium, which may be an electrolytic resolution as in a storage battery, or a solid, gas, or vacuum.
- The main use of electrodes is to generate electrical current and pass it through non-metal objects to essentially alter them in several ways. Electrodes are also used to calculate conductivity.
- The electrode is the location where electron transfer happens. An electrode is classified as either a cathode or an anode counting on the type of chemical response that happens. If an oxidation reaction happens at an electrode.

Answer:
Facultative anaerobe.
Explanation:
Bacteria can be classified on the basis of their nutrition requirement and on the basis of different condition of oxygen in which they live. Two main types of bacteria are aerobic bacteria and anaerobic bacteria.
Anaerobic bacteria grows in the absence of oxygen. The facultative anaerobe bacteria can undergoes the process of respiration in presence as well as in absence of oxygen. Thioglycollate chemicals helps to known the aero tolerance of the organism. The turbidity on the whole tube indicates that the bacteria is facultative anaerobe.
Thus, the correct answer is facultative anaerobe.
