Abstract

The genome of Crassostrea virginica, the American oyster, has been studied by reassociation kinetics in order to construct a profile of DNA sequence frequency components. Oyster DNA has been shown to contain at least 51% single copy DNA sequences and two classes of middle repetitive DNA. The major repetitive class contains sequences which are repeated on the average 20 times and comprise 28% of oyster DNA. The other class represents 10% of oyster DNA and contains sequences repeated approx. 3000 times. In addition the DNA of oyster contains at least 1% foldback sequences. The spectrum of DNA repetition components in the American oyster is similar to that found in the genomes of other mollusks.
