Figure showing packaging of DNA Helix. Observe the figure and answer the following questions.

The region in prokaryotic cell whose DNA is organised in large loops held by proteins is called:

Nucleoid

The correct answer is Option (4) → Nucleoid

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 .The length of the E.coli DNA is 1.36mm.
