Which rRNA is longest?arrow_forwardSuppose your supervisor is working on a molecule “X” with UniProtKB accession number P18564. Being a team member in the project, you have been asked to provide the following information with high accuracy? I. Chromosome number: II. Protein size: III. Number of exons: IV. Stop codon: V. Size of the longest exon in nucleotidesarrow_forwardPlease do answer all the questions. I'll definitely give a like You discovered a halophilic bacterium and want to characterize the mechanism involved in producing mature tRNA molecules from larger tRNA precursors. You isolated a large complex composed of a protein component and an RNA component that is capable of cleaving the larger tRNA precursor. To determine which one of the two components is responsible for catalysis, you perform an in vitro tRNA cleavage assay in the proper buffer conditions, including a low concentration of Mg2+ and 0.5 M bovine serum albumin (BSA). BSA is not specific for this reaction. The table below summarizes the results after performing eight separate reactions. The + symbol indicates the included reaction components. Q. Based on the results obtained, what can you conclude about the composition of the biological catalyst required for the maturation of tRNA? Q. Indicate which reactions helped you make your conclusion. Why? Q. Which reactions allowed you…arrow_forward

Plasmids carrying either the wild-type tRNA Me transcription unit or the mutant gene were microinjected into Xenopus laevis oocytes together with [a-3 PIGIP. The oocytes were incubated for 5 hours, and then RNA was extracted from whole oocytes, separated nuclei, or cytoplasm. RNA samples were subjected to polyacrylamide gel electrophoresis and autoradiographyarrow_forwarddiscuss using named examples some of the disadvantages of protein engineering using site directed and random mutagenesisarrow_forwardThe lab you joined recently want to investigate the role of uncoupling protein in-vivo models.
