THE DNA OF CAENORHABDITIS ELEGANS

[摘要] Chemical analysis and a study of renaturation kinetics show that the nematode, Caenorhabditis elegans , has a haploid DNA content of 8 x IO7 base pairs (20 times the genome of E. coli). Eighty-three percent of the DNA sequences are unique. The mean base composition is 36% GC; a small component, containing the rRNA cistrons, has a base composition of 51% GC. The haploid genome contains about 300 genes for 4s RNA, 110 for 5s RNA, and 55 for (18 + 28)S RNA.
