DNA can't directly order a cell to make proteins. It has to be transcribed into RNA orribonucleic acid. RNA, in turn, is translated bycellular machineryto make amino acids, which it joins together to form polypeptides and proteins...
Structure, folding and flexibility of co-transcriptional RNA origami RNA nanostructures can be designed to fold during transcription, but the solution structure has remained elusive. Here the authors use cryogenic electron microscopy to determine the structure of a panel of RNA origami shapes and uncove...
2.7.U7 Codons of three bases on mRNA correspond to one amino acid in a polypeptide. 2.7.S4 Deducing the DNA base sequence for the mRNA strand. 转录的过程只需要RNA聚合酶(RNA polymerase),它会识别DNA上某个基因的启动子(promoter),DNA上某段基因片段首先打开双螺旋,然后期中一条链,叫做编码链(coding...
There is no amino acid attached because one is not needed. The amide linker has a free amine which is protected by an Fmoc group. Upon removal of the Fmoc group, an amide bond may be formed with the incoming activated amino acid. Nothing special needs to be done, although you must tell...
Rapid association of Ku to DSBs promotes NHEJ by recruiting DNA-PKcs. Sequential phosphorylation events on multiple DNA-PKcs amino acid clusters favors the initial processing of DNA ends by ARTEMIS, followed by DNA-PKcs-dependent protection of DNA ends required for DNA ligation. ...
DNA-RNA 杂交链或带有 RNA 质粒的，细菌相对常见。现存细胞生物通常以酶修掉基因组里混入的RNA，缺失...
RNA Pull-down:通过体外转录RNA并用生物素进行标记,然后与胞浆蛋白混合物共同孵育形成RNA蛋白质复合物,然后用链霉亲和素标记的磁珠分离纯化该复合物(利用生物素与链霉亲和素的非共价亲和作用)。洗脱后进行检测,如果检测蛋白为已知蛋白可通过WB进行鉴定,如果检测未知蛋白则可以结合质谱进行鉴定。流程为提取细胞胞浆蛋白...
Initiation:Transcription begins at a promoter: a specific region of a gene. RNA polymerase binds to the promoter. This signals the DNA to unwind. The enzyme is now ready to make mRNA Elongation:Nucleotides are added to the mRNA strand
