Which of the following statements is not true of the lac operon promoter? which of the following statements is not true of the lac operon promoter? rna polymerase binds to this promoter weakly in the absence of cap. rna polymerase and laci repressor protein cannot bind to the promoter dna simultaneously. cap has an activating region that recruit rna polymerase to this promoter. the -35 sequence deviates from the consensus sequence for sigma 70 promoters. the promoter has an up-element that directly binds to the alpha subunit of rna polymerase..

The correct answer is the -35 sequence deviates from the consensus sequence for sigma 70 promoters.

Explanation:

The -10 and -35 are the two most important promoter region present in upstream region of prokaryotic DNA.

          The -35  promoter region contain a consensus sequence TTGACA

This sequence never deviates from the its original position for sigma 70 promoters.During transcription RNA polymerase enzyme itself moves along the template DNA strand to copy the genetic information present within the DNA molecule which result in the formation of bases in the mRNA molecule and these base sequences are complementary to that of template DNA strand.

transcription is a process in which information is rewritten. it is something our cells must do, in a more specialized and narrowly defined way. in biology, transcription is the process of copying out the dna sequence of a gene in the similar alphabet of rna. it needs to happen in the nucleus because that's where the dna is. dna is always inside the nucleus unless the cell is dividing.

transcription is the first step in gene expression, which involves copying a gene's dna sequence to make an rna molecule. transcription is performed by rna polymerases. it has three stages: initiation, elongation, and termination. rna molecules must be processed after transcription in eukaryotes.

explanation:

long version:

the protein synthesis consists two processes which are, transcription and translation. transcription takes place in the nucleus. it uses dna as a template to make an rna molecule. rna then leaves the nucleus and goes to a ribosome in the cytoplasm, where translation occurs. transcription is the first part of the central dogma of molecular biology: dna → rna. it is the transfer of genetic instructions in dna to messenger rna (mrna). during transcription, a strand of mrna is made that is complementary to a strand of dna.  

these three stages are:

  initiation: in which   is the beginning of transcription.occuring when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

    elongation: in which is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

    termination: in which is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.
