Since DNA is a hydrophilic molecules, it cannot pass through cell membranes. Why ?

Select the wrong statement (a) Presence of chromogenic substrate gives blue color colonies if the plasmid in the bacteria does not have an insert (b) Retroviruses in animals have the ability to transform normal cells into cancerous cells (c) In microinjection, cells are bombarded with high velocity microparticles of gold or tungsten coated with DNA (d) Since DNA is a hydrophilic molecule it cannot pass through cell membranes

DNA is a hydrophilic molecule, so it cannot pass through cell membranes. Then how does a recombinant DNA inserted into a plasmid vector, enter into a bacterial cell ?

DNA is a hydrophilic molecule, it cannot pass through cell membrane. In order to force bacteria to take up the plasmid, the bacterial cells must be made competent to take up DNA. Write the procedure for making the cell competent?

Since DNA is a ............ molecule, it cannot pass through cell membranes.

DNA cannot pass through a cell membrane as

Sound cannot pass through
