What is the doctrine of Specific Nerve Energies?

Since the blood is already separated form the cellular components and the plasma, blood typing can be a challenge if the medical technologist does not know the theory. Antigens are membrane proteins on the red blood cells. There are 2 types of antigens namely the A antigen and B antigen. Blood types are according to the antigen present in the red blood cells. Blood type O has no antigens in the red cell surface, blood type A has A antigen, blood type B has B antigen, and blood type AB has both A and B antigens. In identifying the antigen, the researcher should extract the cellular components rather the plasma. The plasma, on the other hand, contains antibodies.

If you wanted to sequence the genome of Ötzi, the 5,300-year-old "Iceman" mummy found in the Alps in 1991, which method would yo

Delvig [45]

The question is incomplete as it does not have the options which are:

a) DNA

b) AGCT

c) PCR

d) SNP

Answer:

PCR (polymerase chain reaction)

Explanation:

The polymerase chain reaction is the technique which replicates and produces multiple copies of the DNA molecule artificially in a short period of time.

The PCR technique employs a variety of enzymes and all the prerequisites which are required in the DNA replication in vivo conditions.

In the given question, if the genome of the mummy has to sequence then after the collection of samples from the bones, the DNA has to replicate through the process of PCR. The samples from the different bone structures can be compared and analysed and a complete genome sequence can be analysed.

Thus, PCR is correct.

Prior to modern DNA analysis, morphology (study of physical characteristics) was used to classify organisms. As a result of DNA

Usimov [2.4K]

Answer:

The classification of the organisms are done on the basis of their characteristics and differences among them. DNA sequencing is the most appropriate methods of the organisms classification.

The DNA analysis can be misleading as well. This mainly occurs in the case of analogous traits as these traits are similar to some homologous traits. The similar environmental conditions can also leads to the misleading of the organisms.
