A "TATA box" is:

a) the translation termination sequence.
b) a base sequence in the promoters of eukaryotes facilitates assembly of the DNA.
c) polymerase transcription complex.
d) an example of one of the translation stop codons.

Respuesta :

b) option is correct

Explanation:

  • Eukaryotic promoters are 1000 base pairs (bp) long and present upstream to downstream  
  • Eukaryotic promoters can be divided into two separate parts: Core promoter and regulatory sequence  
  • Core promoter is the site where RNA Polymerase II binds and initiate transcription, it includes two consensus sequences called TATA box and initiator region  
  • RNA Polymerase II is a large proteinaceous complex which consists of more than 12 subunits
  • Regulatory sequence includes GC box, CAAT box and downstream promoter element
