Question

The regulation of gene expression is more complex in eukaryotic cells because the:

• A. Inhibitory or activating molecules may not help to regulate transcription.
• B. Gene expression differentiates specialised cells.
• C. Operons are controlled by more than one promoter region.
• D. The chromosomes are linear and more numerous.

Answer 1

The correct option is B Gene expression differentiates specialised cells.

Eukaryotic gene expression is complex and it occurs in 4 different levels because the processes of transcription and translation are physically separated. The expression of genes form different types of proteins which results in the differentiation of cells specialised for specific functions.
