Q. Consider the following statements regarding Dark DNA:
1.Dark DNA refers to genomic regions that are easily identified using standard sequencing but have no known biological function.
2.Recent research suggests these regions may influence gene regulation and species adaptation, despite being traditionally labeled as “junk DNA.”
Which of the statements given above is/are correct?
Answer: B
Notes:
Explanation:
Statement 2 is correct. Recent research has overturned the traditional view of junk DNA non-coding, repetitive, or intergenic sequences—revealing that these regions are actually essential for gene regulation and species adaptation.
Statement 1 is incorrect: Because Dark DNA is characterized by being difficult to detect or interpret using standard methods, often due to high mutation rates.
