Some transcription factors, such as leucine zipper proteins, form homodimers or heterodimers. How does this increase
  the complexity of available strategies of gene regulation? What will be an ideal response?

Question 2

Identify two ways in which posttranscriptional gene regulation occurs in eukaryotes and briefly explain each What will be an ideal response?

Answer to q. 1

The example given in the text proposes three regulatory proteins: A, B, and C. If these form
dimers, three homodimers and three heterodimers are possible. Having multiple combinations
of regulatory proteins increases the possible mechanisms available for gene regulation.

Answer to q. 2

The addition of a poly- A- tail to eukaryotic mRNA appears necessary for translation. PremRNA
molecules have alternative splicing patterns to produce different types of proteins in
different tissues
