Macrophages are also able to eat any cell that is infected by a bacterium or virus. This helps your body to remain as healthy as possible. Sometimes, the macrophages are given the wrong...

Examining coding structure and redundancy in DNA. How does DNA protect itself from life's uncertainty?

0739-5175/06/$20.00©2006IEEE T he genetic code instructs proteins on the translation of nucleotides to amino acids, but this example is only one of many signals encoded in DNA. It is well known that these protein-coding regions have the lowest mutation rates in the DNA strand. So, the question arises: how does DNA protect itself from error? A review of DNA signal content, redundancy, and mutati...
