2. Once a polymerase is successfully bound to a DNA template, it often requires the assistance of other proteins in order to leave the stable promoter complex and begin elongating the nascent RNA strand.
3. In this process, which is distinct from the process described above, argonaut-bound siRNA recognizes nascent RNA transcripts or the target DNA to guide the methylation and silencing of the target genomic region.
4. Such sites can be visualized by allowing engaged polymerases to extend their transcripts in tagged precursors ( Br-UTP or Br-U ) and immuno-labeling the tagged nascent RNA . Transcription factories can also be localized using fluorescence in situ hybridization or marked by antibodies directed against polymerases.
5. ASF / SF2 is involved in genomic stability; it is thought that RNA Polymerase recruits ASF / SF2 to nascent RNA transcripts to impede formation of mutagenic DNA : RNA hybrid R loop structures between the transcript and the template DNA . In this way, ASF / SF2 is protecting cells from the potential deleterious effects of transcription itself.
6. It's difficult to find nascent rna in a sentence. 用nascent rna造句挺难的
