Cancer is caused by mistakes in DNA, and a new study finds that in most cancer cases. These mistakes are completely random. They are not due to heredity or environmental factors, but rather the results of random errors. About 66 percent of cancers were due to random mistakes, 29 percent were due to environmental factors or people’s lifestyles, and 5 percent (5%) due to inherited mutations [2]
The transcription of a gene begins with transcription elements, mostly protein and RNAs, binding to regulatory sites on DNA. The frequency of this binding affects the level of expression. Experiments have verified that a stronger binding site will increase the effect of a protein on transcription rate. On the other hand, since the DNA sequences is unchanged,
