codons的例句大全

Recognition Analysis of Two Kinds of Methionine Codons in Human cDNA Sequences

人cDNA序列中二类甲硫氨酸密码子的区分

Codon bias refers to the nonrandom usage of synonymous codons for encoding amino acids in organisms. As it is related to the carrier molecular of genetic information ( DNA) and functional molecular ( protein) of life, this phenomenon implicates important biological sense.

密码子偏性是指生物体中编码同一种氨基酸的同义密码子的非均衡使用现象，由于这一现象与遗传信息的载体分子DNA和生物功能分子蛋白质相关联，所以具有重要的生物学意义；

This numerical value can act as the lowest estimator of the mutation rate of codons controlled by the coding DNA.

这个数值可以作为由DNA编码区控制的密码子突变率的最低估计值。

The time development equations of usage frequencies of codons are deduced by considering base mutations and the select effects on the level of amino acid.

考虑碱基突变与氨基酸水平上的选择效应，导出了密码子使用频经的时间演化方程；

More than double mutations in different codons of one rifampin-susceptible strain were also detected, this may be the effect of suppressor mutation.

还发现在两株利福平敏感菌株的rpoB基因中也存在两处以上的突变位点，并分别位于不同的氨基酸密码子中，这可能是第二位点突变对菌株耐利福平突变产生抑制的结果。

Objective To elucidate the evolution pattern of human influenza virus A H3 subtype by detecting positive selected codons in hemagglutinin gene.

目的筛选H3N2亚型人甲型流感病毒红细胞凝聚素（HA1）序列中的正向选择位点，为进一步揭示流感病毒的变异规律。

β-thalassemia frameshift at codons 8/ 9 (+ g) found in Chinese population for the first time

在新疆维吾尔族中首次发现β地中海贫血CDs8／9（＋G）基因突变

The most frequently used codons were NNA and the most infrequently were NNG.

使用频率最高密码子为NNA，使用频率最低的密码子为NNG。
