 shows once and for all that no consistent patterns of genes across the human genome exist to distinguish one race from another. People who have lived in the same geographic region for many generations may have some alleles in common, but no allele will be found in all members of one population and in no members of any other

DNA studies do not indicate that separate classifiable subspecies exist within modern humans. While different genes for physical traits such as skin and hair color can be identified between individuals, no consistent patterns of genes across the human genome exist to distinguish one race from another. There also is no genetic basis for divisions of human ethnicity. People who have lived in the same geographic region for many generations may have some alleles in common, but no allele will be found in all members of one population and in no members of any other.

is an encoder of information that works analogously to a four-letter alphabet much like how we arrange letters into words and phrases with specific meanings.

The way DNA encodes information is analogous to how we arrange the letters of the alphabet into words and phrases with specific meanings. The word rat, for example, evokes a rodent; the words tarand art, which contain the same letters, mean very different things. We can think of nucleotides as a four-letter alphabet. Specific sequences of these four nucleotides encode the information in genes. Many genes provide the blueprints for making proteins, which are the major players in building and maintaining the cell and carrying out its activities.

has so much storage capacity that a single lily seed has as much information as sixty Encyclopaedia Britannica and a primitive amoeba as much has one-thousand.

There is enough storage capacity in the DNA of a single lily seed or a single salamander sperm to store the Encyclopædia Britannica 60 times over. Some species of the unjustly called ‘primitive’ amoebas have as much information in their DNA as 1,000 Encyclopædia Britannicas.

DNA is not really a thing, it is a memory. — Deepak Chopra

is so efficient that all the information . . . necessary to specify the design of all the species of organisms which have ever existed on the planet . . . could be held in a teaspoon and there would still be room left for all the information in every book ever written.
