All of the following techniques involve hybridization between single-stranded nucleic acid molecules except:
Savatey [412]

Answer:

RFLP analysis.

Explanation:

RFLP (Restriction fragment length polymorphism ) may be defined as a molecular technique used to determine the location of a particular gene in the DNA sequences. The individuals among the population can be easily identified by RFLP analysis.

The restriction enzyme is used for the digestion of DNA sample. The restriction fragments are then visualized by running the fragments on gel electrophoresis. The hybridization between single stranded nucleic acid is not involved in the RFLP.

Thus, the correct answer is option (1).

The most important factor that determines the percent of oxygen saturation of hemoglobin is
erik [133]

Answer:

This question lacks options, options are:

a) The partial pressure of oxygen

b) Acidity

c) The partial pressure of carbon dioxide

d) Temperature

e) BPG

The correct answer is a. The most important factor that determines the percent of oxygen saturation of hemoglobin is <u>The partial pressure of oxygen </u>.

Explanation:

Hemoglobin is an oxygen transport protein. Partial Oxygen Pressure (PaO2), measures the pressure of dissolved oxygen in the blood, that is, it shows how well oxygen passes from the lungs into the bloodstream. A high partial pressure of oxygen in the blood produces an almost complete saturation of hemoglobin, which indicates the maximum amount of oxygen that combines, but when PaO2 is reduced, so is hemoglobin saturation, when saturation is below 90% hypoxemia occurs, that is, the level below normal blood oxygen levels.
