1. Question
Consider the following statements regarding Mitochondrial Replacement Therapy:
- Mitochondrial Replacement Therapy (MRT) is a new form of reproductive in-vitro fertilization (IVF) that involves replacing a woman’s abnormal mitochondrial DNA (mt-DNA) with a donor’s healthy mt-DNA.
- In 2015, the United Kingdom became the first country to regulate MRT.
Which of the statements given above is/are correct?
CorrectAnswer: C
About Mitochondrial Replacement Therapy
- Mitochondrial Replacement Therapy (MRT) is a new form of reproductive in-vitro fertilization (IVF) that involves replacing a woman’s abnormal mitochondrial DNA (mt-DNA) with a donor’s healthy mt-DNA.
- Purpose: MRT is primarily performed to prevent women who are carriers of mitochondrial diseases from passing on these heritable genetic diseases to their children.
- DNA Types: Humans have two types of DNA in their cells: nuclear DNA, inherited from both parents, and mitochondrial DNA (mtDNA), inherited only from the mother.
- In 2015, the United Kingdom became the first country to regulate MRT, establishing legal and ethical guidelines for its use.
IncorrectAnswer: C

3. Question
Consider the following statements about the Fluorescence Microscopy:
1. Fluorescence microscopy is a technique that involves viewing how the object re-emits light that it has absorbed.
2. Fluorescence microscopy is useful for imaging specific features of small specimens, such as microbes.
Which of the statements given above is/are correct?CorrectAnswer: c
About Fluorescence Microscopy:
• Fluorescence microscopy is a technique that uses the principles of fluorescence to study an object. This involves viewing how the object re-emits light that it has absorbed, i.e., how it fluoresces.How it works?
• The way fluorescence microscopy works is by illuminating the object with a specific wavelength of light.
• Particles within the object, called fluorophores, absorb the light and re-emit it at a higher wavelength or different color.
• Before being viewed through the microscope, the object is infused with fluorophores to make it fluorescent.
• As the fluorophores fluoresce, the microscope can track them as they move within the object, allowing visualization of its internal structure and characteristics.
• Different fluorophores have been developed by scientists to study various entities such as specific parts of DNA and protein complexes.Applications:
• Fluorescence microscopy is useful for imaging specific features of small specimens, such as microbes.
• It can enhance the visualization of 3-D features at small scales.
• The technique allows for multicolor staining and labeling of structures within cells, as well as measuring the physiological state of a cell.
• The most popular application of fluorescence microscopy is for studying dynamic behavior in live-cell imaging.
• Multiple types of molecules can now be stained with different colors, enabling simultaneous tracking and observation of various molecules.IncorrectAnswer: c

4. Question
Which of the following statements regarding the Authorised Economic Operator (AEO) Programme are correct?
1. An AEO is a business entity engaged in domestic goods movement, requiring compliance with national customs law standards.
2. Approval for AEO status is granted solely by the World Customs Organization (WCO), without any involvement of national administrations.Which of the statements given above is/are correct?
CorrectAnswer: (a)
Explanation:
Statement 1 is correct. An AEO is indeed a business entity engaged in international goods movement, requiring compliance with national customs law standards, as mentioned in the overview of the AEO Programme.
Statement 2 is incorrect. Approval for AEO status is granted by or on behalf of the national administration, adhering to the World Customs Organization (WCO) guidelines, not solely by the WCO itself. Therefore, only statement 1 is correct, making option (a) the correct answer.IncorrectAnswer: (a)
Explanation:
Statement 1 is correct. An AEO is indeed a business entity engaged in international goods movement, requiring compliance with national customs law standards, as mentioned in the overview of the AEO Programme.
Statement 2 is incorrect. Approval for AEO status is granted by or on behalf of the national administration, adhering to the World Customs Organization (WCO) guidelines, not solely by the WCO itself. Therefore, only statement 1 is correct, making option (a) the correct answer. - Question 5 of 5
