What triggers DNA transcription?

The process of transcription begins when an enzyme called RNA polymerase (RNA pol) attaches to the template DNA strand and begins to catalyze production of complementary RNA.

Why is transcription important in DNA?

The initiation of transcription is an especially important step in gene expression because it is the main point at which the cell regulates which proteins are to be produced and at what rate.

What is transcription of DNA?

​Transcription Transcription, as related to genomics, is the process of making an RNA copy of a gene’s DNA sequence. This copy, called messenger RNA (mRNA), carries the gene’s protein information encoded in DNA.

Where does DNA transcription occur?

nucleus
The process of Transcription takes place in the cytoplasm in prokaryotes and in nucleus in eukaryotes. It uses DNA as a template to make an RNA (mRNA) molecule. During transcription, a strand of mRNA is made that is complementary to a strand of DNA . Figure 1 shows how this occurs.

Where does transcription take place in the cell?

the nucleus
Thus, in eukaryotes, while transcription occurs in the nucleus, translation occurs in the cytoplasm.

What would happen without transcription?

If a gene is not transcribed in a cell, it can’t be used to make a protein in that cell. If a gene does get transcribed, it is likely going to be used to make a protein (expressed). In general, the more a gene is transcribed, the more protein that will be made.

What stage does transcription end?

Transcription ends in a process called termination. Termination depends on sequences in the RNA, which signal that the transcript is finished.

What phase does transcription cease?

Step 3: Termination Termination 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.

Which of the following will happen after transcription?

Transcription termination The process of ending transcription is called termination, and it happens once the polymerase transcribes a sequence of DNA known as a terminator.

Which side of DNA is transcribed?

The antisense strand of DNA is read by RNA polymerase from the 3′ end to the 5′ end during transcription (3′ → 5′). The complementary RNA is created in the opposite direction, in the 5′ → 3′ direction, matching the sequence of the sense strand with the exception of switching uracil for thymine.
