pseudogenes 英s'juːdəʊdʒenz美s'juːdəʊdʒenz COCA²²⁸¹⁴⁹BNC¹⁴⁴⁶⁶⁴⁺³ 基本例句 假基因¹⁰⁰原型pseudogene的复数 And at least two examples of pseudogenes behaving in a similar manner have been documented so far. 目前发现,至少有两个伪基因也具有类似的行为。192.192.169.81 As the sequence and annotation of the human genome itself are refined and updated, characterization of pseudogenes will improve as well. 然而在仔细研究并更新人类基因组的序列资料和注释之后,相信伪基因的鑑定也会随之进步。192.192.169.81 Comparisons of pseudogenes in related genomes can nonetheless reveal important information about the history of specific genes and the general workings of molecular evolution. 然而比较相近生物基因组的伪基因,却可揭露特定基因和一般分子演化的重要资讯。192.192.169.81 Different people have different combinations of pseudogenes, however. 然而,不同人的“假基因”的结合方式也不同。 yeeyan Early efforts to catalogue pseudogenes were largely driven by the need to distinguish them from true genes when annotating genome sequences. 早期分类整理伪基因的工作,主要是为了在解析基因时,将它们和真正的基因区别开来。192.192.169.81 Influence of neighboring base composition on nucleotide substitution bias was observed in the sequence of nuclear pseudogenes and chloroplast non- coding and coding sequences. 核苷酸替换偏好性受其相邻碱基组成的影响现象已经在核基因组假基因序列和叶绿体基因组的非编码序列和编码序列中发现。 dictall These observations indicate that very disparate events have led to independent bursts of retrotransposition that created pseudogenes in each of the lineages. 这项观察显示,各种不同的机缘导致独立的反转录移位,而造就两种生物世系各自不同的伪基因。192.192.169.81 Using the rate of sequence decay relative to the parent genes to determine their age, it is also clear that many pseudogenes in the human and mouse genomes have arisen at different times. 科学家利用伪基因相对于原基因的损毁率来判定它们的形成年代,结果发现人类和小鼠许多伪基因都是在不同时期形成的。192.192.169.81 What is more, a number of those transcriptionally active intergenic areas overlap with pseudogenes, suggesting that some pseudogenes may have life left in them. 此外,有些活跃的基因间区域与伪基因的所在位置重叠,显示有一些伪基因其实仍有生命。192.192.169.81 Yet despite this similarity in functional genes and overall genome structure, just a small fraction of the known human pseudogenes have an obvious counterpart in the mouse. 尽管人类和小鼠在功能性基因和整个基因组具有高度相似性,但在已鑑定出来的人类伪基因中,却仅有一小部份可在小鼠基因组中找到对应的伪基因。192.192.169.81 |
