What are the 4 steps of protein creation?
Steps of Transcription
- Initiation is the beginning of transcription. It occurs when the enzyme RNA polymerase binds to a region of a gene called the promoter.
- Elongation is the addition of nucleotides to the mRNA strand.
- Termination is the ending of transcription. The mRNA strand is complete, and it detaches from DNA.
What are the 2 main steps needed to go from gene to protein?
The journey from gene to protein is complex and tightly controlled within each cell. It consists of two major steps: transcription and translation.
What are the 5 steps of building a protein?

What is the correct order of making a protein?
Protein synthesis is the process in which cells make proteins. It occurs in two stages: transcription and translation. Transcription is the transfer of genetic instructions in DNA to mRNA in the nucleus. It includes three steps: initiation, elongation, and termination.
Where does the second step of protein synthesis?
Translation
Translation is the second step in protein synthesis. It is shown in Figure below. Translation takes place at a ribosome in the cytoplasm. During translation, the genetic code in mRNA is read to make a protein.
How is protein made?
To build proteins, cells use a complex assembly of molecules called a ribosome. The ribosome assembles amino acids into the proper order and links them together via peptide bonds. This process, known as translation, creates a long string of amino acids called a polypeptide chain.
How does a cell make proteins?
When the cell needs to make a protein, mRNA is created in the nucleus. The mRNA is then sent out of the nucleus and to the ribosomes. When it is time to make the protein, the two subunits come together and combine with the mRNA. The subunits lock onto the mRNA and start the protein synthesis.
What is the first step of protein synthesis?
Transcription
The first step of protein synthesis is called Transcription. It occurs in the nucleus. During transcription, mRNA transcribes (copies) DNA. DNA is “unzipped” and the mRNA strand copies a strand of DNA.
How many stages are there in the making of proteins starting with a string of amino acids )?
Relate protein synthesis and its two major phases to the central dogma of molecular biology. Identify the steps of transcription, and summarize what happens during each step. Explain how mRNA is processed before it leaves the nucleus. Describe what happens during the translation phase of protein synthesis.
Which is the correct order of events when a protein is made in the process of translation quizlet?
The correct sequence of events in translation is: A. initiation, termination, elongation.
What is the second step in the process of protein synthesis which takes place at the ribosome?
The Process Of Translation Is the Second Step Of Protein Synthesis. As already mentioned, the process of translation happens in the cytoplasm, where mRNA binds with ribosomes , which are the exact protein synthesis sites.
