MCQ
Given below are two statements:
Statement I: In prokaryotes, the positively charged DNA is held with some negatively charged proteins in a region called nucleoid.
Statement II: In eukaryotes, the negatively charged DNA is wrapped around the positively charged histone octamer to form nucleolus.
Choose the correct answer from the options given below:
  • A
    Statement I is incorrect but Statement II is true.
  • B
    Both Statement I and Statement II are true.
  • Both Statement I and Statement II are false.
  • D
    Statement I is correct but Statement II is false.

Answer

Correct option: C.
Both Statement I and Statement II are false.
(C)
In prokaryotes, such as, E. coli, though they do not have a defined nucleus, the DNA is not scattered throughout the cell. DNA (being negatively charged) is held with some proteins (that have positive charges) in a region termed as 'nucleoid".
The DNA in nucleoid is organised in large loops held by proteins.
