Research cancer mutation. Provide the link to the research article that gives you your information. One good resource to use is PubMed. Then answer the following questions, in 3 paragraphs, 3-5 sentences each. 1. What kind of disease/cancer does this mutation cause? 2.What happens during transcription to cause this mutation? 3.

Can you please help with 1a,1b, and 1c please 1a. Find a paper published in a scientific journal between January 2018 and September 2022 that addresses the role of an example of histone modification in affecting expression of a gene by altering histone acetylation/chromatin state of the DNA encoding that gene. What organism and/or cell type did the authors do their study in?  1b. Which histone(s) were affected by the acetylation and/or deacetylation?       What gene did they show had altered expression levels in response to the change in histone acetylation? 1c. what effect did the histone modification they studied have on that gene's level of expression - was expression of the gene they examined increased or decreased?
