Answer #1

During trasncription in eukaryotes, RNA polymerase binds to the transcription initation complex, allowing transcription to occur. To initate transcription in eukaryotes, some trasncription factors are needed. TFIID is the first protein/trasncriptional factor that binds to the TATA binding site (TATA box) in the DNA promotor site to initiate trasncription. TFIID contains a subunit called TBP i.e. TATA binding protein which is general transcription factor that binds specifically to a DNA sequence called the TATA box. This DNA sequence is found about 30 base pairs upstream of the transcription start site in some eukaryotic gene promoters.

The transcription of a gene involves copying DNA nucleotides from DNA into a sequence of RNA nucleotides. Many regulatory factors can help facilitate the transcription processes. One region that affects transcription is the terminator region, which is located on mRNA, downstream of the coding segment on DNA, in the 5' end of the gene on DNA, downstream of the coding segment on mRNA at the 5' end on DNA, within the coding region
