最终依赖 RNA 连 接酶将 mRNA 连接起来,这一系列酶促反应完成编 辑过程.这种编辑形式首先在锥虫线粒体中发现[2], 其细胞色素 C 氧化酶亚基Ⅱ(Cox Ⅱ)转录本与基 因序列不匹配,存在 4 个非 DNA 编码的尿嘧啶,后来在变形菌(Proteusbacillus vulgaris) 和副粘病毒 (Paramyxoviridae)基因中也分别发现了 C ...
When absolute representation in biological processes was considered, DNA-templated regulation of transcrip- tion, protein catabolic processes, and glutathione metabolic processes were over-represented in libraries of Day 3 ticks (B1‒B4 and S1‒S4), while DNA-templated regulation of ...
No such peak was observed in reactions that lacked either the DNA template or acyl-tRNA, confirming templated ribosomal initiation with α-thio acid 13, 2-benzylmalonic acid (14) and N-formyl-l-α-amino acid 15. Two peaks of identical mass were observed in the extracted ion chromatogram (...
The biological process categories analysis showed that parental gene functions were involved in regulation of membrane depolarization during action potential, regulation of DNA-templated transcription, initiation, “de novo” GDP-L-fucose biosynthetic process, cytoplasm organization, negative regulation of ...

(GO:2,001,141), regulation of cellular macromolecule biosynthetic process (GO:2,000,112), regulation of nucleic acid-templated transcription (GO:1,903,506), and heterocycle biosynthetic process (GO:0018130) were suppressed in the biological process (BP) category irrespective of genotype and time...
During this process, peptides may have been produced directly on an instructive amino acid binding RNA (a DRT; Direct RNA Template). Combination of observed stereochemical selectivity with adaptation and co-evolutionary refinement is logically required, and also potentially sufficient, to create the ...
These genes code for many of the biosynthetic proteins involved in processing miRNAs through canonical pathways. Interestingly, these genes are mainly downregulated following the zygote stage, with the exception that Ago1, Ago3 and Ago4 expression levels are increased after transition to the two-cell...
