Concentration (%) A researcher is studying environmental conditions that cause the expression of genes that ultimately affects the phenotype. The following schematic diagram depicts the researcher's findings regarding the expression of gene Z (4 points): Regulatory gene DNA lacl MRNA 5 Promoter Operator GeneZ RNA polymerase Protein Active repressor In his research, the scientist determined that the active repressor expression was determined by environmental pH levels. In his investigation, he obtained the following data: Concentration of active repressor at specific pH 12 10 8 16 4 2 12 Concentration (%) 1 2 3 4 5 6 7 8 9 10 11 12 13 14 pH According to the data obtained by the researcher, predict which of the following environmental conditions is mostly likely to cause the expression of the gene Z? Strong acid (pH 2) Neutral (pH 7) Mild base (pH 8) ○ Strong base (pH 12)

DNA methylation status is associated with transcriptional activity. First, describe the specific mechanism by which DNA methylation can control gene activation. Next, hypothesize what would happen to transcription in a cell that expressed an nonfunctional maintenance methyltransferase. Please give me long detailed answer.
Below are data from Jimenez et al (2022) depicting cellular expression patterns of the tumor suppressor transcription factor p53 (a gene commonly mutated in cancers). They explored oscillating expression patterns found in a mutated human cell line. Panel D shows measurements of changes in p53 mRNA levels measured using two different approaches; figure E shows measurements of protein levels from the same samples. The numbers on either side indicate the observed fold change (FC) in relative abundance of these molecules (note that any difference in values obtained between the two methods are not relevant for this question).
