Types of Satellite DNA
Satellite DNA, together with minisatellite and microsatellite DNA, constitute the tandem repeats.
Some types of satellite DNA in humans are:
| Type | Size of repeat unit (bp) | Location |
|---|---|---|
| α (alphoid DNA) | 171 | All chromosomes |
| β | 68 | Centromeres of chromosomes 1, 9, 13, 14, 15, 21, 22 and Y |
| Satellite 1 | 25-48 | Centromeres and other regions in heterochromatin of most chromosomes |
| Satellite 2 | 5 | Most chromosomes |
| Satellite 3 | 5 | Most chromosomes |

“Science is intimately integrated with the whole social structure and cultural tradition. They mutually support one other—only in certain types of society can science flourish, and conversely without a continuous and healthy development and application of science such a society cannot function properly.”
—Talcott Parsons (1902–1979)
“He’s one of those know-it-all types that, if you flatter the wig off him, he chatter like a goony bird at mating time.”
—Michael Blankfort. Lewis Milestone. Johnson (Reginald Gardner)
“Books are the best things, well used; abused, among the worst. What is the right use? What is the one end, which all means go to effect? They are for nothing but to inspire. I had better never see a book, than to be warped by its attraction clean out of my own orbit, and made a satellite instead of a system.”
—Ralph Waldo Emerson (1803–1882)
“Here [in London, history] ... seemed the very fabric of things, as if the city were a single growth of stone and brick, uncounted strata of message and meaning, age upon age, generated over the centuries to the dictates of some now all-but-unreadable DNA of commerce and empire.”
—William Gibson (b. 1948)
