Question

1. Explain in multicellular eukaryotes, how a protein can be expressed in one cell and not another by explaining cis elements and trans acting factors.

Answer 1

Cis Elements & Trans Acting Factors

Step-by-step explanation:

• The transcription inception complex is made out of advertiser groupings and DNA restricting proteins. These two segments of transcription are typically portrayed as Cis-acting components and trans-acting factors
• Cis-acting elements - DNA groupings in the region of the basic part of a quality that is required for quality articulation
• Trans-acting factor - factors, normally viewed as proteins, that quandary to the cis-acting groupings to control quality articulation.
• Subunits of RNA polymerase
• Bind to RNA Polymerase to settle the inception complex
• Bind to all promoters at explicit groupings yet not to RNA Polymerase (TFIID factor which ties to the TATA box)
• Bind to a couple of promoters and are required for translation commencement; these are certain controllers of quality articulation
