Many of the changes caused by these mutations will be unnoticeable; however, by chance a mutation may occur in a gene that produces a phenotypic change.

The RhoA oncogene , have been revealed in recent years, are closely related to various malignant tumours. RhoA, belonging to Rho family, is one member of the ras superfamily, whose encoding production, namely RhoA protein, pertaining to micromolecular mass GTP conjugated protein family, in GTP conjunctive active form and GDP conjunctive unreactive form. It exist in the latter form in normal cells and the switch of the two forms enables them to educe functions, paralleling"molecular switch", the diminutive G protein in activated state being able to activate the wink dromo-iter to work functions, which is in the resemblance of process during which the Ras genic mutation induces its continous activations.

RhoA是近年来新发现的与多种恶性肿瘤密切相关的癌基因，RhoA属于Rho亚家族，是ras基因超家族的一员，其编码产物RhoA蛋白属于小分子量GTP结合蛋白族，分为GTP结合的活性型和GDP结合的非活性型两类，在正常细胞内以GDP结合的非活性型存在，两种活性形式之间的转换使他们能够发挥一种类似"分子开关"的作用，活性态的小G蛋白能激活下游的信号传导通路，行使其功能。

This paper presents a maximum criterion-based phylogeny analysis method for unrooted trees. To increase the confidence level of the derived evolutionary trees, we use bootstrapping and consensus analysis in conjunction with a genetic algorithm for crossover and mutation between evolutionary trees.

本论文采用最大概率字元特徵式的评分方式，以及无根的建构方法，利用基因演算法对所有可能的树的子树做交配与突变，再使用统计自序法与一致演化树法来增加树的可信度。

The results showed that the correlation between road network density and ecosystem distribution was mainly determined by the road networks grades with the tendency that correlation decreased with upgrading of the road networks, and the scaling effects of the road networks can be divided into 4 categories: rising, descending, mutation and unscaled.

选取2km×2km、4km×4km、6km×6km、… \，20km×20km网格进行多尺度相关分析和方差分析，研究云南纵向岭谷区道路网络与生态系统分布的相关性及其独立和交互作用，分析道路网络对生态系统影响的尺度效应。然后又进一步研究了道路网络和地形因子（比如海拔、坡度和坡向等）对生态系统的独立和交互作用。

The absence or mutation of SRY gene may be concerned with the pathogenesis of hypospadias which is a sex upgrowth abnormality.

(1)SRY基因不是性别决定的唯一基因，SRY基因缺失或突变可能导致性发育的一系列异常改变，尿道下裂的发生与SRY的缺失、变异有关。

RESULTS: There was a point mutation in the 12th codon in Patu8988 cell; the amino acid was mutated to valine.

结果：Patu8988胰腺癌细胞株12位密码子点突变为GGT→GTT，12位氨基酸突变为缬氨酸。

The variegation of petals originates chiefly from gene mutation and viral infection.

花瓣彩斑主要由基因突变或病毒入侵而形成。

The results showed that the changes of the types were not caused by new cell mutation, but by translocation of the different cell types of variegation. The changes of division direction of white cells and green cells resulted that some of the green epidermal cells translocated into the second layer and it pushed furthermore the origin white cells of the second layer into the third layer, so that the variegation altered.

Pollock'突变型异化不是由于细胞突变形成，而是由于质体突变型白色细胞和原型绿色细胞在生长发育过程中相互竞争转轨所致，即白色细胞和原型绿色细胞改变了分裂方向，部分表皮绿色细胞进人第二层，挤压第二层白色细胞转轨进人第三层，导致细胞类型的移位，从而形成异型斑。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。
