a. Describe the functions of different RNA molecules during protein synthesis. b. How might these RNA functions suggest the appearance of this nucleic acid before DNA and proteins in a model of the origin of life? Explain nucleic acids and gene expression by describing ...
Next suggest how RNA compares to DNA in regards to genetic material. Summarize how DNA and RNA differ in structure and function. Examine three differences between DNA and RNA then explain two main reasons why DNA is the most favorable molecul...
4.1, describe how the guide RNA and Cas9 enzyme are used to cut both strands of DNA.3](b) (i) Explain why gene editing done on embryos help to prevent children born from suffering from the genetic disease.2] 相关知识点: 试题来源: 解析 (ii)Suggest and explain if the mutation ...
A virus, the simplest physical object in biology, consists of a protein shell called the capsid, which protects its nucleic acid genome—RNA or DNA. The capsid can be cylindrical or conical in shape, but more commonly it assumes an icosahedral structure, like a soccer ball. Capsid formation ...
Biophysics X-ray crystal structures explain DNA-hairpin promoter binding and de novo transcription initiation for the N4 virion RNA polymerase THE PENNSYLVANIA STATE UNIVERSITY Katsuhiko Murakami GleghornMichael LN4 vRNAP is a virion-encapsidated RNA polymerase (vRNAP) from the N4 bacteriophage that ...
Once a transcription factor has bound to DNA, it engages special cell machinery to initiate RNA synthesis from that particular gene. A large number of such factors is known (over 1,500 in humans). Their combinations regulate how active transcription should be and whether it should happen at ...
We used three biological replicates from each group ofS. paraplesiaflowers for RNA sequencing. The RNA of the flower samples was extracted using the RNAprep Pure Plant Kit (TIANGEN, Beijing, China). The cDNA library was generated from the total RNA using the NEBNext UltraTM RNA Library Prep...
How is the human iNKT TCR structurally and functionally similar and dissimilar to the TCRs expressed by conventional {eq}\alpha {/eq}{eq}\beta {/eq} T cells? Explain. Living Cell: A living cell is a basic unit of all living ...
DNA was assessed for quality using a NanoDrop spectrophotometer (Thermo Scientific), for integrity using gel electrophoresis (agarose, 2%), and for quantity using a Qubit fluorometer (Life Technologies). High-quality samples from 212 individuals were used to produce double-digest restriction site-...
Explain how the process of transcription and translation makes proteins from DNA. Use the following terms in your explanation: template strand, RNA polymerase, nucleus, mRNA, cytoplasm, ribosome, tRNA, amino acid, peptide bond, growing protein chain, codo What is the difference ...
