You perform a northern blot to determine whether CFTR (Cystic fibrosis transmembrane conductance regulator) mRNA is expressed in small intestine tissue. You do not detect any MRNA in this sample. Which of the following is a valid conclusion from your experiment? O This gene is not expressed in this organism O This gene is likely not transcribed in the small intestine O Small intestine cells do not contain the CFTR gene O There is no MRNA, because it has all been converted to protein

Define (whether post-transcriptional, post-translational, transcription) and describe the regulation of the Ferretin mRNA in the diagram below.
The above answer did not address the question in the sense that the answer did not indicate which protein involved in the pathways could be measured in the nucleus of cells and be confident in the results? I reiterate the question as follows: You want to do a single Western blot to measure changes in signaling activity, regardless of which pathway is being activated. For which protein involved in these pathways could you measure the levels in the nucleus of cells and be confident in your results? Why?

Which of the following statements did Yamanaka rely on to produce induced pluripotent stem cells (IPSC)? [Note: This is higher level thinking. All statements on their own are correct and may be related to IPSC production but there is only one statement that played an essential role in the production of IPSC) O A. A proportion of embryonic stem cells can differentiate into adult stem cells. B. Only a small proportion of genes are expressed in each celI. C. Telomerase is active in pluripotent stem cells. D. All genes retain the potential to be expressed.
Using bacteria that express double stranded RNA upon induction by IPTG, investigators have constructed an RNAi library that allows you to feed C. elegans bacteria that expresses dsRNA corresponding to a given gene to obtain progeny that have been compromised for this target mRNA. This was performed for every predicted gene in the animal. From this experiment, 1200 genes of the 19000 predicted genes tested caused sterility in adult animals. 200 of the 1200 candidates that cased sterility were of unknown function. Q4a) What can we conclude from this information? Q4b) What processes are the genes with unknown function likely involved in?
