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.

Cis Elements & Trans Acting Factors

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 factorsCis-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

Answer

three main types of plate boundaries: divergent, convergent, A divergent boundary occurs when two tectonic plates move away from each other When two plates come together, it is known as a convergent boundary. The impact of the colliding plates can cause the edges of one or both plates to buckle up into a mountain ranges or one of the plates may bend down into a deep seafloor trench. A chain of volcanoes often forms parallel to convergent plate boundaries and powerful earthquakes are common along these boundaries.
