Q. In eukaryotes, gene expression can be regulated at following levels, except at
A) formation of primary transcript
B) transport of mRNA from nucleus to the cytoplasm
C) packaging of DNA around the histone octamer
D) processing level or splicing
Explanation
In eukaryotes, regulation of gene expression could be exerted at transcriptional level, splicing, transport of mRNA from nucleus to cytoplasm and translation. All the above events are the major steps of polypeptide and these steps can be represented through central dogma as shown below. [image:6_image96.wmf]
