Cell Biology Internship Test
Intern has to take Cell Biology internship test in which they will be asked 50 multiple-choice questions. They have to score grade A or A* on this test to be eligible for the internship. Here’s a sample set of questions on the Cell Biology topic.
1. Which microscope was used by Anton van Leeuwenhoek?
(B) confocal microscope
(D) compound microscope
Explanation: Antonie Van Leeuwenhoek used single-lens microscope which he constructed by himself. The biconvex lens used was capable of magnifying 270 times and a resolution of 1.35 micro-meters.
2. Motor proteins help in regulation which activities in a cell?
Explanation: Cells perform lot of bustling activities in their daily discourse. This requires a lot of mechanical activities, regulation, uptake etc. The motor protein is one class of proteins amongst many that help in the mechanical activities of the cell.
3. The rotary engine made of protein at the base of the flagella is driven by ______________
(A) Vanderwaal’s foce
(B) Proton- motive force
(C) Electron passage
(D) Exchange of sodium and potassium ions
Explanation: Proton motive force is the flow of protons or hydrogen ions across the bacterial cell membrane due to a concentration gradient set up by cell’s metabolism. This force drives the motor engine at the base of the flagella and helps in flagellar movement.
4. Which of the following enables a Dengue virus to affect human beings?
(A) RNA Polymerase enzyme
(B) DNA Polymerase enzyme
(C) Reverse Transcriptase enzyme
(D) Gyrase enzyme
Explanation: The Dengue Virus is a retrovirus which contains RNA as its genetic material. So, to infect a human being by integrating its genome into the human DNA genome, it is necessary to convert its RNA sequence into DNA. Reverse Transcriptase enzyme catalyzes the reverse transcription of viral RNA into DNA.
5. Buffers usually contain ________________ with its conjugate ____________
(A) weak base, base
(B) strong base, acid
(C) weak acid, base
(D) weak acid, acid
Explanation: Buffers are solutions that resists change in pH. They can be made up of a weak acid and its conjugate base or a weak base and its conjugate acid. An example of a buffer is a solution of acetic acid(weak aci(D) and sodium acetate(conjugate base).
