The correct answer is "the absence of the UCD protein due to miR-5 inhibiting transcription of the UCD mRNA transcript.
Explanation: Since UCD protein is formed by the activity of miR-5 on mRNA, if somehow miR-5's activity is compromised the whole process will be stopped from UCD formation to histone acetylation.
Option 5 is wrong because miR-5 doesn't directly act on p101 protein but it helps in the formation of UCD protein which is an activator of p101.

In eukaryotes, miR-5 is a microRNA with sequence complementarity to the 3 UTR of the mRNA transcript encoded by the UCD gene. The UCD gene encodes for a protein that acts as an allosteric activator of the protein p101. The p101 protein is a histone acetyl transferase (HAT) which is an enzyme that acetylates histones when the protein is in its active form In a lung cancer cell line, the p101 protein is overly active leading to misregulation of gene...
