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
