Given below are two statements:
Statements 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 nucleosome.
In the light of the above statements, choose the correct answer from the options given below :
Both Statement I and Statement II are true.
Both Statement I and Statement II are false.
Statement I is correct but statement II is false.
Statement I incorrect but statement II is true.
Answers (1)
The correct answer is Option 4) Statement I is incorrect, but statement II is true.
Statement I: In prokaryotes, the positively charged DNA is held with some negatively charged proteins in a region called nucleoid.
This statement is incorrect. In prokaryotes, the DNA is not associated with proteins like histones to form nucleosomes as seen in eukaryotes. Instead, prokaryotic DNA is typically found in a region called the nucleoid, where it is condensed and organized to some extent, but without the association of histones or other proteins.
Statement II: In eukaryotes, the negatively charged DNA is wrapped around the positively charged histone octamer to form nucleosome.
This statement is true. In eukaryotes, DNA is wrapped around histone proteins to form nucleosomes. The DNA molecule is negatively charged due to its phosphate backbone, while the histone proteins are positively charged. The interaction between the negatively charged DNA and the positively charged histones allows for the compaction and organization of DNA into a higher-order structure.
Therefore, the correct answer is Option 4) Statement I is incorrect, but statement II is true.
