What are the 4 stages of transcription?

Stages of Transcription
  • Initiation. Transcription is catalysed by the enzyme RNA polymerase, which attaches to and moves along the DNA molecule until it recognises a promoter sequence. …
  • Elongation. …
  • Termination. …
  • 5′ Capping. …
  • Polyadenylation. …
  • Splicing.

What is the process of transcription step by step?

Transcription occurs in the three steps—initiation, elongation, and termination—all shown here. Transcription takes place in three steps: initiation, elongation, and termination.

What is the order of transcription?

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

How does transcription end in eukaryotes?

RNA Polymerase II terminates transcription at random locations past the end of the gene being transcribed. The newly-synthesized RNA is cleaved at a sequence-specified location and released before transcription terminates.

What is the first step in transcription?

Transcription Initiation. The first step in transcription is initiation, when the RNA pol binds to the DNA upstream (5′) of the gene at a specialized sequence called a promoter (Figure 2a). In bacteria, promoters are usually composed of three sequence elements, whereas in eukaryotes, there are as many as seven elements …

What are the 5 steps of translation biology?

Translation (Protein Synthesis)
  • Initiation. In this step the small subunit part of the ribosome attaches to the 5′ end of the mRNA strand. …
  • Elongation. …
  • Termination.

What are 3 steps of translation?

Translation of an mRNA molecule by the ribosome occurs in three stages: initiation, elongation, and termination.

What is translation and its steps?

Translation is the process by which the genetic code contained within a messenger RNA (mRNA) molecule is decoded to produce a specific sequence of amino acids in a polypeptide chain. It occurs in the cytoplasm following DNA transcription and, like transcription, has three stages: initiation, elongation and termination.

What are the major steps of translation?

Translation of an mRNA molecule occurs in three stages: initiation, elongation, and termination.

What are the steps of transcription quizlet?

Terms in this set (3)
  • First Step. RNA polymerase unzips the DNA double helix (initiation)
  • Second Step. RNA Nucleotides are formed from the nucleotides in the DNA template strand (Elongation)
  • Third Step. The mRNA that is formed leaves the nucleous (termination)
