A study of the interaction between ethidium bromide and rye chromatin: comparison with calf thymus chromatin.

abstract：:A highly repetitive DNA sequence from tilapia (Oreochromis mossambicus/hornorum) has been cloned and sequenced. It is a tandemly arrayed sequence of 237 bp and constitutes 7% of the fish genome. The copy number of the repeat is approximately 3 x 10(5) per haploid genome. DNA sequence analysis of 7 cloned repeats revea...
