Which characteristics of DNA polymerase I raised doubts that its in vivo function is the synthesis of DNA leading to complete replication?

Answers

Answer 1
Answer:

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).

If you were trying to identify an unknown adult animal that must be either an echinoderm or chordate, which morphological feature(s) would guarantee that your organism was an echinoderm rather than a chordate.

Answers

Answer:

The radial symmetry and mesodermal skeleton in echinodems

Bilateral symmetry and internal skeleton of chordates

Explanation:

The echinoderms have radial symmetry and their skeleton is mesodermal made up of calcites known as ossicles while the chordates have bilateral symmetry and their internal skeleton is made up of bones and cartilages.

Imagine you discover a yeast mutant that exhibits a general inability to grow and thrive compared to wild-type yeast. You predict that the mutant has a defect in a basic process necessary for survival and therefore examine the cellular levels of 200 common proteins, as well as the levels of tRNAs and rRNAs. You discover that tRNA and rRNA levels are normal, but the levels of all of the proteins you examine are much lower than they are in the wild-type yeast. This suggests that there is a general defect in:
