Solution
The correct option is C plasmids
To isolate DNA from a cell, various enzymes are used in order to dissolve the cell wall, cell membrane and various other biomolecules (proteins, lipids, RNA).
As peptidoglycan (murein) is present in the cell wall of bacterial cells, the cell used here to isolate DNA is a bacterial cell.
The enzyme lysozyme usually degrades peptidoglycan in the bacterial cell wall.
A bacterial cell is a prokaryotic cell which lacks membrane bound organelles and a well-defined nucleus (nuclear membrane absent).
70S ribosomes are present in bacterial cells. 80S ribosomes are found in the cytoplasm of eukaryotic cells.
Plasmids are extrachromosomal circular DNA rings which replicate independently and are found in certain bacterial cells.
Hence, the correct answer is option c.
