In mammals, the action of modifying gene expression in which one X chromosome is inactivated in the cell of females differs from how miRNA performs gene silencing in that
A. miRNA blocks transcription factors.
B. miRNA is a method of posttranscriptional gene silencing.
C. miRNA modifies histones on DNA.
D. miRNA methylates acetyl groups to repress translation.
Homework Answers
B is correct option because miRNA is method of postranscriptional gene silencing means mRNA has formed from DNA and then this mRNA is degraded by miRNA.
In case of gene inactivation, is occur pretranscriptionally means before transcription.

A genetically engineered plasmid Ficarries all of the elements of the lac operon, but replaces the structural genes with the reporter gene green fluorescent protein (GFP). The repressor allele cannot bind lactose, and the OC allele cannot be bound by the repressor. Given the following genotypes and growth media that does not contain glucose, indicate in the table below whether you expect to see b-galactosidase activity and glowing green colonies of E. coli by selecting Yes or No. growth media...
