What are the steps involved in transcription of a gene?

Transcription takes place in three steps: initiation, elongation, and termination.

How eukaryotic genes are transcribed?

Eukaryotic transcription is regulated by a large number of proteins, ranging from sequence-specific DNA binding factors to chromatin regulators to the general transcription machinery and their regulators (reviewed by Berger, 2000; Li et al., 2007a; Orphanides and Reinberg, 2002; Pugh, 2000; Struhl et al., 1998).

What are the steps in eukaryotic gene regulation?

Stages of eukaryotic gene expression (any of which can be potentially regulated).

  • Chromatin structure. Chromatin may be tightly compacted or loose and open.
  • Transcription.
  • Processing and export.
  • mRNA stability.
  • Translation.
  • Protein processing.

Where does transcription occur in eukaryotes?

The eukaryotic nucleus therefore provides a distinct compartment within the cell, allowing transcription and splicing to proceed prior to the beginning of translation. Thus, in eukaryotes, while transcription occurs in the nucleus, translation occurs in the cytoplasm.

What are the three stages of transcription and what happens in each?

Transcription takes place in three steps: initiation, elongation, and termination. The steps are illustrated in Figure 2. Figure 2. Transcription occurs in the three steps—initiation, elongation, and termination—all shown here.

Which parts of a eukaryotic gene are transcribed?

Which parts of a eukaryotic gene are transcribed? Both exons and introns. Also 5′ and 3′ untranslated regions are transcribed.

How does transcription and translation occur in eukaryotes?

Transcription occurs in the nucleus in eukaryotic organisms, while translation occurs in the cytoplasm and endoplasmic reticulum. Both processes occur in the cytoplasm in prokaryotes. The factor controlling these processes is RNA polymerase in transcription and ribosomes in translation.

What is the third step of transcription?

How do eukaryotic cells regulate transcription?

As in bacteria, transcription in eukaryotic cells is controlled by proteins that bind to specific regulatory sequences and modulate the activity of RNA polymerase.

Which part of eukaryotic genes are transcribed?

A eukaryotic cell has a nucleus that separates the processes of transcription and translation. Eukaryotic transcription occurs within the nucleus where DNA is packaged into nucleosomes and higher order chromatin structures.
