摘要：

Four mouse ribosomal gene fragments cloned in λgtWES were studied by restriction enzyme mapping and Southern transfer experiments. These fragments were found to contain 18S DNA and transcribed as well as non-transcribed spacer DNA. Variation in the structure of these mouse DNA inserts was limited to one region of spacer DNA. This variation may reflect real structural differences found in mouse ribosomal genes or possibly deletion events which occurred during cloning. The transcribed regions of the inserts appear identical to one another and restriction enzyme fragments from this region correspond to fragments observed in digests of total mouse DNA. These clones will be useful in studying the structure of transcribed spacer DNA including the ribosomal gene promoter. © 1979.
