  1. Antigen-antibody

  2. Enzyme-ligand

  3. Nucleic acid- DNA

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Biosensors rely on specific biological interactions to detect analytes. Antigen-antibody, enzyme-ligand, and nucleic acid interactions are all standard mechanisms used in various types of biosensors.

Oxidation of ethanol can be sensed by which of the following biosensor?

  1. Electrochemical biosensor

  2. Microbial biosensor

  3. Ozone biosensor

  4. None of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A- Electrochemical biosensors are simple tools which are utilized to determine the measurement of electronic current or conductance changes done by the bio-electrodes. The electrochemical sensor converts the electrochemical information into an analytical signal. This type of biosensor is generally made up of two basic parts - a biological component & an electronic component.

Blood glucose biosensor is an example of ___________.

  1. Conduct metric biosensor

  2. Potentiometric biosensor

  3. Amperometric biosensor

  4. None of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
Amperometric biosensors are biosensors which function by the production of a current when a potential is applied between two electrodes. One of its application is the determination of glucose concentrations by the use of an immobilised glucose oxidase membrane. Reaction results in a reduction of the oxygen concentration as it diffuses through the biocatalytic membrane to the cathode, this being detected by a reduction in the current between the electrodes
So, the correct answer is option C.

Which of the following biosensors is used for medical diagnostics and forensic science?

  1. Ozone biosensor

  2. DNA biosensor

  3. Microbial biosensor

  4. Both B and C
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

DNA biosensors have various applications, commonly used for medical diagnostics, forensic science, agriculture, or even environmental clean-up efforts. It function as the two strands of DNA stick to each other by virtue of chemical attractive forces and that is, two strands that match up at every nucleotide position gives rise to a fluorescent signal that is then transmitted to a signal generator.

So, the correct answer is option B.

Which of the enzyme can be used in electrochemical biosensors?

  1. Ligase

  2. Endonuclease

  3. Dehydrogenase

  4. None of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Electrochemical biosensors are those biosensors that are mostly based on enzymes and catalyses the reaction that produces or consumes electrons. The reactions are redox types and the enzymes that catalyze these oxidations are called dehydrogenases.

So, the correct answer is option C.

Which of the following is considered as a physical component of biosensor?

  1. Analyte

  2. Amplifier

  3. Transducer

  4. Both B and C
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

A biosensor typically consists of a biological recognition element and a physical transducer that converts the biological signal into an electrical one. An amplifier is often used to boost this signal, making both components essential physical parts of the system.

____ are miniaturized labs which help in detection of diseases.

  1. Biotech labs

  2. Biomolecular labs

  3. Biolabs

  4. Biochips
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

In molecular biology, biochips are essentially miniaturized laboratories that can perform hundreds or thousands of simultaneous biochemical reactions. Biochips enable researchers to quickly screen large numbers of biological analytes for a variety of purposes, from disease diagnosis to detection of bioterrorism agents.

SCID is caused by defective gene coding for enzyme ______________.

  1. Adenosine deaminase

  2. Adenosine transaminase

  3. Adenosine transferase

  4. Guanosine transaminaseGuanosine deaminase
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Adenosine deaminase deficiency SCID, commonly called ADA SCID, is a very rare genetic disorder. It is caused by a mutation in the gene that encodes a protein called adenosine deaminase (ADA).
