结果表明,在与水稻、玉米和麦类作物的比较中,竹类植物与水稻有着最近的亲缘关系和更相似的基因序列特征(GC含量分布和密码子使用频率),它们甚至比水稻与玉米或水稻与麦类之间的亲缘关系更近。
4)  double-frequency cipher
双频密码
5)  codon use frequency (FCU)
绝对密码子使用频率
6)  optimal codon
高表达优越密码子
1.
lipolytica selected by high-frequency codon analysis with optimal codons selected by traditional methods, the result shows that high-frequency codon analysis is feasible.
lipolytica高频密码子和传统的高表达优越密码子分析法筛选出的优越密码子进行比较 ,证实高频密码子分析法的可靠性 。
补充资料:无义密码子
分子式:
CAS号:

性质:一种终止信号(nonsense signal)。不为氨基酸编码的核苷酸三联体(如UAA,UAG)。UGA是大肠杆菌中的无义密码子,但在脊椎动物中则可能为半胱氨酸编码。UAA和UAG被认为是“标点”密码子,它们不为氨基酸编码,但能间断信使RNA(m RNA)链的解读,从而使已合成的多肽释放出来(即导致多肽链合成的终止)。
