Question

Differentiate the nuclear regions of a bacterial cell with a human cell. Add a note on their functions

Answer 1

DIFFERENCESBACTERIAL CELLHUMAN CELLCellCell is isolated and Independent. It survives as an individual on its own.Human cellsare in a group and not isolated. It is dependent on other cells for survival.Cell wallThick protective cell wall is present covering the whole cell.The wall is absentCell membrane is made ofIs made of phospholipid bilyaer. But the memebrance lacks sterols.Lipid bi-layer with phosphate molecules. It is hydrophilic to external and hydrophobic in the inner wall.Cell membrane hasNo cytoplasmic bridges as there is only one cell.Cytoplasmic bridges are present which help in inter-cellular transport in between neighboring cells.Cell shapeCells can be of different shapesOnly spherical or ovalCell appendages (External parts)Present. Flagella for movement, pili for sexual reproduction.Absent mostly. Except for ciliated cells in respiratory tract & gut.NucleusNucleus is Absent. Instead nuclear content like DNA are present in cytoplasm. No distinct nucleus, so called as prokaryoteProminent nucleus with nuclear membrane. So called as an eukaryote type.DNA synthesis & ElongationEnzyme DNA Gyrase is involved.Enzyme Topoisomerase is involvedRNA (ribo nucleic acid)70 s type with 50s and 30s type sub units.80 s type with 60 s and 40 s sub units.
