need to know if correct
44 F Nonsense-mediated mRNA decay refers to the degradation of introns after splicing 45. Exon skipping and cryptic splice-site selection are two types of splicing errors. 46. Transcription activators can promote nucleosome remodeling by recruiting histone modifying enzymes. 47. RNA polymerase Il terminates transcription precisely at the AAUAAA 48. During protein translation, Kozak consensus sequences are required for termination 49. In regards to transcription, DNA tooping refers to the removal of DNA looped around histone...

You want to make E. coli bacteria that glow green. Your plan is to insert the gene for green fluorescent protein (GFP) from a jellyfish (a eukaryote) into the genome of the bacteria so that the mRNA is transcribed by the E. coli cells and translated into protein. What changes do you need to make to the jellyfish GFP gene sequence to make sure that the bacteria will make a functional protein? Why? (1 point) A type of amatoxin binds...

A particular type of glucose binding protein binds to glucose with an affinity of 0.43 µM. In other words, 1/K = 0.43 µM, where K is the equilibrium constant for the association of glucose with the protein. If glucose concentration is 1 mM, then approximately what fraction of glucose bindingA. Almost noneB. Almost allC. About halfD. About 10%In principle, a eukaryotic cell can regulate gene expression at any step in the pathway from DNA to the active protein, including marking...
