The cell membrane slows the movement of water into or out of the cell and this is vital when treating diseases.
<h3>
What is a cell membrane?</h3>
The cell membrane provides protection for a cell and also provides a fixed environment inside the cell. It transports nutrients into the cell and transports toxic substances out of the cell.
The cell membrane is simply one of the major barriers that pathogens need to conquer e.g. a virus first needs to attach itself to the cell membrane and injects its genetic material into the host cell before replication.
Estrogens passively diffuse across the plasma membrane and then bind to their receptor proteins in the cytoplasm of the target cells.
When estrogen enters the nucleus, it binds to the estrogen receptor, causing it to pair up and form a dimer. Then this dimer then binds to several dozen specific sites in the DNA, strategically placed next to the genes that need to be activated.

The answer is C hope this helps.
DNA model given by Watson and Creek in the year of 1953 gave a very detailed study regarding the structure of B DNA which is valid till date and is essentially corroborating with Chargaff's data and Xray diffraction pattern.
<h3><u>Explanation:</u></h3>
The DNA is the most common nucleic acid found in the living organisms as a genetic material. As stated by Watson and Creek, this DNA contains a double helical structure with two sugar phosphate backbones and the nitrogen bases getting projected from it inwards. The backbones are formed of ribose sugar and phosphate and joined together with a phosphodiester bond. The ribose sugar is attached to phosphates at its 3' and 5' Carbon atoms. The nitrogen bases found in DNA are Adenine, Guanine, Thymine and Cytosine. The Adenine has two hydrogen bonds with thymine and guanine has 3 hydrogen bonds with cytosine.
Each full turn of a helix is 34A and each base pair is 3.4A apart. The distance between two strands of DNA is 20A.
Chargaff's rule regarding the equal amount of adenine and thymine as well as guanine and cytosine is matching with this structure. All the other rules also do match with this DNA structure.
