1.A laboratory technologist, who was working in a given molecular biology laboratory, planned to
perform Southern blotting techniques. Accordingly, after extracting and purifying DNA, he runs
agarose gel electrophoresis. He also added a buffer to this agarose gel to separate the doubleοΏΎstrand DNA, to facilitate blotting of single strands to the nitrocellulose paper.
What is the most likely buffer added to agarose gel in this case?
A. Strong Acidic
B. Weak acidic
C. Strong alkaline
D. Weak alkaline
try your answer.......

A 4th year student was performing differential white cell count on an apparently healthy control
study participant to determine the relative count. The blood film was well prepared and well
stained using Romanowsky stains. He faced difficulty identifying Neutrophil from Eosinophilic
and asked his supervisor.
What is the most likely key feature is NOT used in this case?
A. Size
B. Number of lobes
C. Primary granules
D. Specific granule

A laboratory technologist, who was working in a molecular biology laboratory, prepared the
laboratory for the extraction of Nucleic acids from the blood sample. He has planned to extract
and purify the nucleic acids in traditional methods by heating the sample in the presence of
detergents and phenol solution. Furthermore, he has arranged the removed contaminants by
equilibrium density gradient centrifugation in cesium chloride.
What is the most likely nucleic acid to be extracted as per the technologist's work plan?
A. DNA
B. RNA
C. Cesium chloride
D. Difficult to extract

A laboratory technologist, who was in a molecular biology laboratory, extracted nucleic acids
from biological samples. Next, he assessed the purity of the extracted samples by taking
spectrophotometer readings at 260 and 280 nm. Accordingly, the ratio of the extracted sample
absorbance at 260/280 was 1.9.
What is the most likely absorbance ratio that indicates the nucleic acid status?
A. Lipid contamination
B. Protein contamination
C. No contamination
D. phenol contamination
