Promoter segments, Transcription factors
The initiation of transcription starts when the enzyme RNA
polymerase binds to the DNA at the region called promoter. Each
gene has a promoter and it contains DNA sequences that let RNA
polymerase to attach to the DNA.
Transcription factors are the helper protein cells that bind to the
promoter and helps RNA polymerase to get attached to the DNA.
tRNA and ribosomes does not involve in the process of initiation of transcription.

Identify the statements that are features of a promoter. Pick all that Apply. A. In eukaryotes, the promoter recruits the preinitiation complex, which includes the TATA-binding protein. b. In prokaryotes, the promoter is recognized by general transcription factors (GTF), which recruit the RNA polymerase holoenzyme. c. In eukaryotes, the promoter attracts the small and large ribosomal subunits with the help of initiation factors. d. In prokaryotes, the promoter contains a –35 and –10 region upstream of the transcription start site...
