If the proteins are structural, such as those that comprise skin or bone matrix, a mixture of normal or abnormal products usually produces abnormal skin or bone, and the resulting abnormality is termed a dominant trait or disease. An abnormal gene ...

DNA

...ty of Cambridge The discovery that DNA was the carrier of genetic information was a process which required many earlier discoveries. The existence of DNA was discovered in the mid 19th century . However, it was only in the early 20th century that researchers began suggesting that it might storeb genet...

Diffusion

...ssive transport of ions or molecules by a specific carrier protein in a membrane. As in simple diffusion, net transport is down a concentration gradient, and no additional energy has to be supplied. Compare with diffusion and active transport. Net flux Net flux is used to measure diffusion. Polarity...
