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 nucleosome. |

I: | The process of copying genetic information from one strand of the DNA into RNA is termed as transcription |
II: | A transcription unit in DNA is defined primarily by the three regions in the DNA i.e. a promoter, the structural gene and a terminator. |
