Recently, we found that about half of all REP sequences have the potential to stall ribosomes immediately upstream of the termination codon, leading to endonucleolytic cleavage of the mRNA, and induction of the trans-translation process. As a consequence, the mRNA and almost completed protein ...
EN假设我有一个从1到5的向量，我们在做数据分析的时候，经常需要产生一些重复序列。例如，做差异表达分...
sequence <- c("A", "B", "C") # 使用rep函数复制向量 repeated_sequence <- rep(sequence, times = 3) # 使用paste函数连接复制后的向量 result <- paste(repeated_sequence, collapse = "-") # 输出结果 print(result) 输出结果为:A-B-C-A-B-C-A-B-C 在云计算领域中,粘贴和rep函数指定序列...
For each element of str, the regexprep function applies each expression in sequence. If there are no matches to expression, then newStr is equivalent to str. example newStr = regexprep(str,expression,replace,option1,...optionM) modifies the search using the specified options. For example,...
The database allows for both individual and cross-species proteome analyses and also allows users to upload sequences of interest for analysis by the RepSeq algorithm. Identification of repeat-containing proteins provides researchers with a defined subset of proteins which can be analysed by ...
Rep-PCR：Versalovic于1996年描述的一种细菌基因组指纹分析方法，即细菌基因组重复序列PCR技术（rep-PCR）是扩增细菌基因组中广泛分布的短重复序列，通过电泳条带比较分析，揭示基因组间的差异。细菌基因组中广泛分布的短重复序列（repetitive sequence），包括常用的REP（repetitive Extragenic Palindromic,基因...
unique nucleotide tags (UMIs, see thispaperfor details), which are attached to molecules before sequencing library preparation and allow to backtrack the original sequence of molecule. UMIs make it possible to computationally filter nearly all experimental errors from resulting immune receptor sequences...

If all axes are homed, first raise Z, then move all axes except Z simultaneously to their home position. Once the first axis reaches its home position, the axes will be homed individually in sequence XYZIJKUVW. RequiresQUICK_HOME.
I wanted to create this sequence here using rep() and seq() without using c( ): This is what I have so far: nr_seq<-seq(3,30,3)dr_seq<-seq(2,47,5)nr_terms<-cumprod(nr_seq)dr_terms<-cumprod(dr_seq)req_terms<-nr_terms/dr_terms1+req_terms[1]2.5000002.2857141.9642861.6806721....
