查询词典 repeats

Microsatellites are composed of simple tandem repeats of nucleotides primarily in non-coding gene sequences. The number of repeats is inherited as a codominant trait.

In addition, the promoter of SRPP gene contains a variety of stress-responsive elements, such as HSE,MBS, TC-rich repeats, ABRE, EIRE and W box etc. These data suggest that SRPP is not only involved in rubber biosynthesis, but also plays an important role in response to various stresses in rubber trees.

此外，SRPP基因启动子还具有热激响应元件、干旱胁迫响应元件、防卫和胁迫响应元件（TC-rich repeats）、脱落酸响应元件、赤霉素响应元件和激发子响应元件等，这表明橡胶树SRPP基因不仅参与调控橡胶生物合成，而且可能是橡胶树中响应逆境信号的抗性基因，在橡胶树抵御逆境胁迫的生理过程中发挥重要作用。

DM1 and DM2 gene were amplified by PCR,tested by agarose electrophoresis, then analyzed by genetic analyzer. Results: Myotonia and muscle weakness were the main manifestations associated with heart block (7/8) and cataract (6/7). Electromyologram showed myopathic abnormalities not only in patients but also in other members of the family (5/6). The CTG repeats in DM1 and CCTG repeats in DM2 were all in normal range.

He is a repeater. He repeats not only his own mistakes; he often repeats those of his family and culture.

他老是重蹈覆辙：他不但重复自己的错误，还经常重复他的家庭和文化的错误。

Objective To explore the relationship between 3'-variable numble of tandem repeats (3'-VNTR) of apolipoproteins B and cerebral hemorrhage with family history in Changsha Han Chinese.

目的 探讨载脂蛋白B(apolipoproteins B， apoB)基因3'端可变数目串联重复序列(3'-variable numble of tandem repeats， 3'-VNTR)多态性与长沙地区汉族人群家族聚集性脑出血的关系。

Cultivation density experiment included 3 disposals of 20cm×30cm, 30cm×40cm and 40cm×50cm, with 3 repeats for each disposal; fertilization amount experiment included 4 disposals of 0kg, 450kg, 675kg and 900kg, with 3 repeats for each disposal. The results showed that seeds of Ocimum basilicum Linn.

栽培试验进行栽培密度和施肥对比两种试验；栽培密度试验设20cm×30cm，30cm×40cm，40cm×50cm 3种处理，每种处理3个重复；施肥对比试验设每公顷施复合肥0kg、450kg，675kg，900kg，4种处理，每种处理3个重复。

CRISPRs (Clustered Regularly Interspaced Short Palindromic Repeats), the basis of spoligotyping technology, can provide prokaryotes with heritable adaptive immunity against phages' invasion.

规律成簇的间隔短回文重复（Clustered regularly interspaced short palindromic repeats， CRISPRs）是一类广泛分布于细菌和古菌基因组中的重复结构。

Two molecular forms of Xenopus hatching enzyme, 60kD and 40kD molecules, was obtained during preparation and purification. Both of them were verified as the hatching enzyme molecules, using anti GST UVS.2 antibody as the probe. 60kD molecule was digested or autodigested easily into 40kD molecule during purification. It was indicated that 40kD molecule was probably derived from 60kD molecule with its two CUB repeats lost, and the two CUB repeats may play an important role in recognizing and/or modifying of the molecular structure of vitelline envelope.

在分离纯化非洲爪蟾孵化酶时，得到了60kD和40kD两种分子，用孵化酶的特异性抗GST-UVS.2抗体进行Western杂交的结果证明二者均为孵化酶分子。60kD分子很不稳定，在纯化过程中极易降解，40kD分子可能是由60kD分子经过降解或自身降解丢失了两个CUB重复区而形成的，而CUB重复区很可能在对受精膜分子结构的修饰或改造中具有重要作用。

Abundance orA repeats was similar to C repeats. AC was a little more than two times as abundant much as AG. However, AT and CG repeats were rare. For tri- and tetramer repeats, AGC,AAAC and AAAT predominated while ACG, ACT, AGG, CCG, ATGC, CCCG, ACTG, AACT, ACGT, AGAT, CCGG,ACCT and AGCT were rare. For some pentamer repeats, one was completely absent on a certain chromosome, even on several chromosomes.

对按蚊基因组中微卫星丰度而言，A碱基和C碱基重复在基因组中丰度相似，AC单元的丰度是AG单元的两倍多，然而AT和CG单元非常稀少；对于三四碱基而言，AGC，AAAC和AAAT单元最为丰富，ACG，ACT，AGG，CCG，ATGC，CCCG，ACTG，AACT，ACGT，AGAT，CCGG，ACCT和AGCT单元等均很稀少，而一些五碱基重复，在某条甚至某几条染色体中均未分布。
