摘要
运用重建进化树方法对酵母螺旋酶(Y′-helicaseprotein,YRF)基因以及类YRF基因的ORF(OpenReadingFrame)序列进行了动态聚类,指出了与YRF基因有亲缘关系的ORF,纠正了已公布的酵母基因组中可能存在的错误,给出了新预测的基因位置.并运用基因间关联指数和序列非均匀性指数对所得结论进行了进一步验证.
By using the rebuilding evolutionary tree,the dynamic clustering of the Y′helicase protein and the ORFs similar to gene YRF in sequence in Yeast genome is given.The ORFs that have a close relationship with gene YRF are given.The results show that some mistakes may exist in the published Yeast genome,then the correct results are obtained.Furthermore,by use of Correlation Index between genes and the Heterogeneity Index (HI) of sequences,the results are verified in detial.
