Mutations in the Genome

Estimates are that about 5 percent of cells in your body that multiply and divide mutate. That is, the new cell fails to copy the pattern completely and accurately from the original. Think of a mutation as simply a change in the spelling of a DNA sequence. What does that mean? DNA has or is a genetic language that consists of 64-letters known as codons. This DNA alphabet spells out your genetic code. The letters are organized into words and sentences known as genes. Estimates are that humans have about 30,000 genes (far less than as originally believed). Every person’s DNA contains mutations that typically are quite harmless. Others, however, are harmful and may be responsible for triggering abnormal conditions and specific diseases.
