Answer:
plants grow taller in generations level because the vascular tissue can transport nutrients throughout the body even when it it necessary to go against gravity.
Explanation:
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).
Answer:
The inheritance of ABO blood groups corresponds to an autosomal codominant pattern.
Explanation:
The blood type is defined by the presence of surface antigens in the red blood cell, called A and B. The presence of each antigen is determined by a gene present on the parental chromosomes.
- Blood type A corresponds to the presence of gene A, and its genotypic expression can be A/A or A/O.
- Type B blood, whose genotype is B/B or B/O, is due to the presence of a gene containing the B antigen.
- AB blood -due to codominance- has one gene for A and another for B, with genotype A/B.
- Blood type O, characterised by the absence of surface antigens, behaves like a recessive trait, which only manifests itself in the absence of surface antigens A and B. The genotype is O/O.
The presence of an antigen A or B, suppresses the expression of blood type O, recessive, which will be possible only in its homozygous form.
