Which of the following statements regarding the packaging of DNA is incorrect?
Options
- AIn prokaryotes like E. coli, DNA is held together by some positively charged proteins.
- BIn prokaryotes, the DNA is organized in large loops held by proteins in a region termed as nucleoid.
- CEukaryotes possess a set of positively charged, basic proteins called histones to package their DNA.
- DDue to the absence of a defined nucleus, the negatively charged DNA in prokaryotes is scattered uniformly thro
Correct answer
D. Due to the absence of a defined nucleus, the negatively charged DNA in prokaryotes is scattered uniformly thro
Step-by-step solution
According to NCERT, in prokaryotes such as E. coli, even though they lack a defined nucleus, the DNA is not scattered throughout the cell. The negatively charged DNA is held together by some positively charged proteins in a specific region termed the nucleoid. Here, the DNA is organized in large loops held by proteins. In eukaryotes, DNA packaging is more complex and involves a set of positively charged, basic proteins called histones. Therefore, the statement claiming that prokaryotic DNA is scattered uniformly th
