What are the 4 steps of protein synthesis?
The steps are illustrated in the figure below.
- Initiation is the beginning of transcription. It occurs when the enzyme RNApolymerase 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.

What is the correct order of protein synthesis quizlet?
The messenger molecule (mRNA) carries the DNA copy to the cytoplasm. The messenger molecule (mRNA) is fed through the ribosome 3 bases at a time. Transfer molecules called tRNA bring the correct AA (amino acid) from the cytoplasm to the ribosome. Transfer molecules (tRNA) drop amino acids (AA) off at the ribosome.
What are the 7 stages of protein synthesis?
Terms in this set (12)
- DNA unzips in the nucleus.
- mRNA nucleotides transcribe the complementary DNA message.
- mRNA leaves nucleus and goes to ribosome.
- mRNA attaches to ribosome and first codon is read.
- tRNA brings in proper amino acid from cytoplasm.
- a second tRNA brings in new amino acid.

What are the 9 steps of protein synthesis?
Terms in this set (9)
- DNA unravels, exposing code.
- mRNA comes in.
- transcription (copying genetic code from DNA)
- mRNA exits nucleus, goes to ribosome.
- translation (gives message to ribosome)
- tRNA brings in specific amino acids (anticodons)
- protein synthesis begins.
- peptides.
What is the fifth step in protein synthesis?
(d) Chain Termination: At the time of termination, the terminal codon immediately follows the last amino acid codon. After this, the polypeptide chain, tRNA, mRNA are released. The subunits of ribosomes get dissociated.
What is protein synthesis GCSE?
Protein synthesis occurs in two major phases: Transcription – during which a strand of mRNA is synthesised from a particular gene template. Translation – during which the mRNA attaches to the ribosome, which recruits tRNAs carrying amino acids in order to make a polypeptide.
What is process of protein synthesis?
5.7 Summary. 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.
What are the stages of protein synthesis quizlet?
Terms in this set (5)
- Unzipping. – DNA double helix unwinds to expose a sequence of nitrogenous bases. …
- Transcription. A copy of one of the DNA strand is made. …
- Translation (Initiation) mRNA couples w/ ribosome & tRNA brings free amino acids to ribosomes.
- Elongation. – Anticodon of tRNA recognizes codon on mRNA. …
- Termination.
What is involved in protein synthesis?
Protein synthesis is the creation of proteins by cells that uses DNA, RNA, and various enzymes. It generally includes transcription, translation, and post-translational events, such as protein folding, modifications, and proteolysis.
How do you explain protein synthesis?
Protein biosynthesis (or protein synthesis) is a core biological process, occurring inside cells, balancing the loss of cellular proteins (via degradation or export) through the production of new proteins. Proteins perform a number of critical functions as enzymes, structural proteins or hormones.
What is the first step of protein synthesis quizlet?
The first stage of protein synthesis where the information on a section of DNA (a gene) is copied by making a mRNA molecule from the DNA.

- mRNA leaves nucleus and goes to ribosome.
- mRNA attaches to ribosome and first codon is read.
- tRNA brings in proper amino acid from cytoplasm.
- a second tRNA brings in new amino acid.
Which protein synthesis process comes first?
Transcription Transcription in Protein Synthesis. The transcription process is the first step of protein synthesis. This step transfers genetic information from DNA to the ribosomes of the cytoplasm or rough endoplasmic reticulum. Transcription is divided into three phases: initiation, elongation and termination.
What is the 2nd step of protein synthesis?
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.
What are the four steps of protein synthesis quizlet?
RNA polymerase unzips DNA and free RNA nucleotides join DNA to form mRNA. mRNA moves from the nucleus to the ribosomes. mRNA joins the ribosome, and the anti codons from tRNA join mRNA to form a chain of amino acids. A chain of amino acids is formed from peptide bonds, creating a protein.
What is the first stage of protein synthesis quizlet?
The first stage of protein synthesis is called "mRNA enters the cytoplasm."
What are the three main stages of protein synthesis?
It includes three steps: initiation, elongation, and termination. After the mRNA is processed, it carries the instructions to a ribosome in the cytoplasm.
What are the 3 steps of translation?
Translation of an mRNA molecule by the ribosome occurs in three stages: initiation, elongation, and termination.
What is the 2nd stage of protein synthesis?
The second step of protein synthesis is mRNA Translation (or just Translation). The mRNA Translation step follows right after the first step of protein synthesis called DNA Transcription (or just Transcription).
What are the steps of translation and protein synthesis?
Stages of Translation in Protein Synthesis
- Initiation: Ribosomal subunits bind to mRNA.
- Elongation: The ribosome moves along the mRNA molecule linking amino acids and forming a polypeptide chain.
- Termination: The ribosome reaches a stop codon, which terminates protein synthesis and releases the ribosome.

What is the correct order of the initiation of protein synthesis in the ribosome?
What is the correct order of the initiation of protein synthesis in the ribosome? Translation of an mRNA molecule by the ribosome occurs in three stages: initiation elongation and termination. During initiation the small ribosomal subunit binds to the start of the mRNA sequence.
What are the 5 steps of translation in order?
The multi-step translation process professional translators use
- Step 1: Scope out the text to be translated.
- Step 2: Initial translation.
- Step 3: Review the accuracy of the translation.
- Step 4: Take a break.
- Step 5: Refine translation wording.
What are the 4 steps of transcription?
The major steps of transcription are initiation, promoter clearance, elongation, and termination.
What are the steps of translation protein synthesis?
Stages of Translation in Protein Synthesis
- Initiation: Ribosomal subunits bind to mRNA.
- Elongation: The ribosome moves along the mRNA molecule linking amino acids and forming a polypeptide chain.
- Termination: The ribosome reaches a stop codon, which terminates protein synthesis and releases the ribosome.

What is protein synthesis?
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.
What is the correct order of events during transcription?
Transcription takes place in three steps: initiation, elongation, and termination.
What are the 4 steps of translation?
Translation proceeds in four phases: Activation, initiation, elongation, and termination. In activation, the correct amino acid is covalently bonded to the correct transfer RNA (tRNA).
