In eukaryotes the gene expression is regulated at:
A. Transcriptional level
B. Processing level
C. Transport of mRNA from nucleus to the cytoplasm
D. Translational level
(a) A, C               (b) A, B, C, D                  (c) B, C, D                     (d) A, B, C

Gene expression results in the formation of a polypeptide which in eukaryotes is regulated at following levels:

(i) transcriptional level (formation of primary transcript)

(ii) processing level (regulation of splicing)

(iii) transport of mRNA from nucleus to the cytoplasm

(iv) translational level.
