Conclusion:Asymmetry of codon-pair usage between DNA double strands in above two genomes seemd to be the result of strand-specific mutational biases,and natural selection at the probably acting at the levels of replication,transcription and translation.
结论:造成上述两物种DNA双链间密码对使用不对称的原因可能是DNA链特异的突变偏好性和在复制、转录、翻译水平上的自然选择约束。
