Solution
The correct option is C 1 and 4
Bacteria is a prokaryotic cell where DNA is held by positively charged non-histone proteins in the nucleoid region. There is no nucleus in the cell.
Histones are found in the nucleus of a eukaryotic cell to wrap DNA around itself.
Plasmid is an extrachromosomal, smaller, circular DNA molecule commonly found in bacterial cells and replicates independently. They are generally used in genetic engineering to produce copies of certain genes.
