A possible role of repetitious DNA in recombinatory joining during chromosome rearrangement in Drosophila melanogaster.

Abstract

It is postulated that certain repetitious DNA components play a role in the recombination processes during chromoxome reappangements. When the distribution of silver grain densities after the in situ hybridization of repetitious DNA (RUDKIN and TARTOF 1973) and the distribution of chromosome breaks due to X-irradiation (KAUFMANN 1946) are compared, a strong correlation is found for the euchromatic portion of the D. melanogaster salivary X chromosome. These observations justify the postulate above that certain repetitious DNA provides homologous regions in the DNA of broken chromosome ends necessary for proper recombinatory joining.
