Question

Why or why not?
Do the results shown in Figure 19.5 prove conclusively that histone modifications are causing reduced Hnf4a gene transcription? Why or why not?
No, because histone modifications do not affect transcription
No, because the results demonstrate only a correlation between altered histone modifications and reduced transcription
Yes, because the observed changes in histone modifications are consistent with reduced transcription.
Yes, because histone modification is the only regulatory mechanism that could affect transcription

Answer 1

The correct answer for the question that is being presented above is this one: "Yes, because the observed changes in histone modifications are consistent with reduced transcription." The results shown in Figure 19.5 prove conclusively that histone modifications are causing reduced Hnf4a gene transcription because the observed changes in histone modifications are consistent with reduced transcription.
