The poor printing of our previous Figure 2 (1) is corrected. Codon usage in mRNA sequences just published is also given. A new correspondence analysis is done, based on simultaneous comparison in all mRNA of use of the 61 codons. This analysis reinforces our claim that most genes in a genome, or genome type, have the same coding strategy; that is, they show similar choices among synonymous codons, or among degenerate bases (2). Like analysis on frequency variation in the amino acids coded reveals an entirely different pattern.
我们之前图2(1)印刷质量不佳的问题已得到纠正。同时还给出了刚发表的mRNA序列中的密码子使用情况。基于对所有mRNA中61种密码子使用情况的同步比较,进行了一项新的对应分析。该分析强化了我们的观点,即一个基因组或基因组类型中的大多数基因具有相同的编码策略;也就是说,它们在同义密码子或简并碱基之间表现出相似的选择(2)。就像对编码氨基酸频率变化的分析揭示了一种完全不同的模式。
