Document Summary
As we saw previously the dna is the molecule that used all the cells for storing the information hereditary. Without however, there are differences in terms of the way in which organize the dna, so that can classify into two large groups: cells prokaryotes and eukaryotes. So important it has been this differentiation that was uti- ized for the classification of the beings living in domains and kingdoms. prokaryotic cells, present in the monera kingdom (bacteria), have free dna. It breeds in the cytoplasm in an area called the nucleoid. Let"s see the structural characteristics corresponding to the prokaryotic cell type: wall cell: present one cover of protection called wall cell, which is rigid and is composed of one. 1 | p a g e: extrachromosomal dna: some bacteria also have one or more circular dna molecules smaller than their chromosome, calledplasmids .
