摘要

分析了三种噬菌体的DNA序列，以便定位编码蛋白质的部分。DNA分子上的弱稳定性使我们能够描述基因的开始和结束。对所使用密码子的调查表明，这种弱稳定性的原因是系统地使用了第三位的A- t碱基，这是由于遗传密码的简并而成为可能的。

[Use of the degeneracy of the genetic code by selective pressure to cut up genes of procaryote genomes].

The DNA sequences of three bacteriophages are analysed in order to localise those parts coding for a protein. A weak stability on the DNA molecule allows us to characterize the beginning and the end of genes. A survey of the codons used shows that the cause for this weak stability is the systematic use of A-T bases in third position, which is made possible by the degeneracy of the genetic code.
