All living cells on Earth, without any known exception, store their hereditary information in the form of double-stranded molecules of DNA—long unbranched paired polymer chains, formed always of the same four types of monomers—A, T, C, G. These monomers are strung together in a long linear sequence that encodes the genetic information.
DNA is packed within a chromosome in a cell. There are around 3.16 billion base pairs present in each human cell. These DNAs are spread across in total of 46 chromosomes in a single human cell.
The plasma membrane is called as selectively permeable membrane because it regulates the movement of substances in and out of the cell. It means that the plasma membrane allows some material to pass through it while at the same time it blocks other material from entering through it.
