Answer 1

​Answer:

why dna cannot pass through cell membrane ?

Because DNA is present in the nucleous and the cell membrane is outside the nucleous so it can not pass. DNA being hydrophilic with the sugar-phosphate backbone, can not pass through the cell membrane.The nature of lipid is hydrophobic , so hydrophobic molecules can easily pass the membrane.

how it can pass.​

DNA contains the instructions needed for an organism to develop, survive and reproduce. To carry out these functions, DNA sequences must be converted into messages that can be used to produce proteins, which are the complex molecules that do most of the work in our bodies.
