Abstract
Chemical analysis and a study of renaturation kinetics show that the nematode, Caenorhabditis elegans, has a haploid DNA content of 8 x 10(7) 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.
摘要
化学分析和复性动力学研究表明，线虫秀丽隐杆线虫的单倍体DNA含量为8×10⁷个碱基对（是大肠杆菌基因组的20倍）。83%的DNA序列是独特的。平均碱基组成为36%的GC；一个包含rRNA顺反子的小部分，其碱基组成为51%的GC。单倍体基因组包含约300个4S RNA基因、110个5S RNA基因和55个(18 + 28)S RNA基因。
