10.in which process,transcription or translation,do each of the following function:RNA polymerase,ribosomes,nucleotides,tRNA,pre-mRNA,DNA A site,anticodon,amino acids? 相关知识点: 试题来源: 解析 最上面的算是第二问吧?2、如楼上所说,一是因为DNA不能通过核孔,二是DNA为双螺旋结构,转录成RNA翻译更...
How do transcription and translation result in the expression of genes? Explain the difference between DNA replication and RNA transcription. Explain the role of tRNA in protein synthesis. Include a description of how it interacts with mRNA and the ribosome. ...
Just as with DNA, it is possible to sequence RNA. Transcriptome sequencing can be done to learn more about the actions of a cell and the host organism's DNA, and to identify the places where the expression of genetic information goes wrong. When a liver cell becomes malignant, for example...
D) RNA polymerase. Central Dogma: The Central Dogma in cell biology describes the process by which the flow of information passes from DNA to a functional protein product in the cell. The two main steps in this process are t...
miR-195b deficient mice were obtained by CRISPR-Cas9 gene editing. Two CRISPR guide RNAs (sgRNAs) were designed using CRISPRSCAN31at either side of miR-195b to provide a deletion encompassing the whole gene (Supplementary Fig.1A). They were synthesized by in vitro transcription from DNA templa...
DNA: Structure, Function and DiscoveryNucleic acids are the organic materials present in all organisms in the form of DNA or RNA. These nucleic acids are formed by the combination of nitrogenous bases, sugar molecules and phosphate groups that are linked by different bonds in a series of ...
题目 The site on DNA to which RNA polymerases bind before initiating transcription(起始转录)is called the___ a. terminator b. operator c. promoter d. enhancer e. silencer 相关知识点: 试题来源: 解析 ___ _C _ 反馈 收藏
orRNA. RNA shares a similar structure to DNA, except it contains only one strand, rather than two — so it looks like just one half of a ladder. In addition, while RNA has three of the four nitrogen bases in common with DNA, it uses a base called uracil rather than thymine to pair...
