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 lif
Answer to: List two differences between DNA and RNA and explain how they related to the way the two molecules are treated by the cell. By signing...
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 ...
Name the factors for RNA polymerase enzyme that recognize the start and termination signals on DNA for the transcription process in bacteria. Explain and identify three uses of polymerase chain reaction (PCR). Identify the three component parts of a nucleotide and explain ho...
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...
Like a cookbook in a library, DNA has the information for thousands of “recipes” on how to make each protein in the cell. But that information has to get out into the cell to be used. This is where RNA comes into the picture. RNA is a molecule that is similar t...
For the latter, how does the cell know which switches are to be activated or deactivated; will the cell divide, differentiate, transform or undergo apoptosis or otherwise change its status? What intelligence is required to make these decisions; what is the messenger molecule and how does the ...
To understand how driving bivalents orientate themselves in an oocyte to favour a TRD, they were imaged from the time of nuclear envelope breakdown (NEBD) to anaphase, which is a period of several hours (8.30 ± 1.30 h, mean ± std. dev., 29 oocytes). In all further st...
How do prions differ from viruses and viroids? Explain. What are the most characteristic symptoms of diphtheria, and why was this disease so deadly prior to the use of the vaccine? Explain the difference between viral types - DNA viruses vs RNA viruses. What is the biological and geopol...
Explain the difference between DNA replication and RNA transcription. Explain the biological role of adaptive and innate immunity in vaccination. Describe how and why both types of adaptive immunity can cause problems with organ transplantation.
