Question

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 proteins for the purpose of opening chromatin structure 50. F During PCR, fresh DNA polymerase needs to be added after every denaturation step because it is degraded by the high temperature Section 3 - Bonus Question (4 points) 51. OOO The reason you can use the 5' sequence of the zebrafish GATA-1 gene to drive GFP expression in a tissue-specific manner is because GATA-1 is a zinc finger transcription factor and bands GEP all necessary cis-elements required for tissue-specific GATA.1 expression have been identified GATA-1 and GFP are evolutionarily related to each other and exhibit the same expression pattern in red blood cells you have cloned a TATA consensus sequence from the GATA-1 gene usne of the gene encoding GFP none of the above E
