Initiation:
In the cytoplasm, protein synthesis is actually initiated by the AUG codon on mRNA. The AUG codon signals both the interaction of the ribosome with m-RNA and also the tRNA with the anticodons (UAC). The tRNA which initiates the protein synthesis has N-formyl-methionine attached. The formyl group is really formic acid converted to an amide using the -NH2 group on methionine (left most graphic)
The next step is for a second tRNA to approach the mRNA (codon - CCG). This is the code for proline. The anticodon of the proline tRNA which reads this is GGC. The final process is to start growing peptide chain by having amine of proline to bond to the carboxyl acid group of methinone (met) in order to elongate the peptide.

∙ 11y agoim not sure of what the second step is, but i do have the steps of protein synthesis.
1. Unwinding- DNA opens up to expose the sequence of bases in a gene
2. Transcription- Nucleotides match up with bases to build messenger RNA
3. Exit- Completed m-RNA moves out of the nucleus into the cytoplasm
4. Pick up- Different tranfer RNA molecules collect specific amino acids
5. Translation- As a ribosome moves along the m-RNA, t-RNAs match up
6. Assembly- The amino acids on the t-RNAs are joined to form a protein :)

Protein is then transported where it is destined to work.
Protein synthesis is very important for metabolic activities in our body.

Where does the protein synthesis take place?
On the ribosomes in the cytoplasm of the cellRibosomes
How can mutations affect protein synthesis?
it can cause cancer
Where in a cell does protein synthesis take place?
In cells protein is made when the cells mate and then the synthesis takes place. It takes place in the mitochondria.
The direction of synthesis of an RNA transcript is?
transcription:"the first step in protein synthesis, a sequence of nucleotide bases becomes exposed in an unwound region of a DNA strand. That sequence acts as a template upon which a single strand of RNA - a transcript - is synthesized from free nucleotides."The synthesis of an RNA molecule from the DNA template strand is called transcription.
Where does ribosome synthesis take place?
Ribosomal-based protein synthesis takes place in the cytoplasm of the cell. Peptides are synthesized by the ribosomes, typically on the rough ER of the cell.
What is the degradation and synthesis of protein called?
denaturation for degradation synthesis: first step is Transcription, The second step is Translation; there are additional steps (post-translational modifications) after that the polypeptide is formed including the formation of 3D conformation
Which of these is a step in protein synthesis?
all of the above
The step in protein synthesis where RNA directs the synthesis of a polypeptide or protein is called?
transcription
3 steps of protein synthesis?
In the body, proteins are synthesized inside organelles known as ribosomes. The first step in protein synthesis is the transcription of mRNA from a gene of DNA. The second step is for protein synthesis to begin and the formation of a protein chain to take place. The third step is for the ribosome to terminate production of the protein, hydrolyze the ingredients that initiated protein production, and then release the protein from the ribosome.
Which process is the frist step of protein synthesis?
Transcription
What is the second part of protein synthesis?
translation
Where is the first step of protein synthesis occur?
on the ribosomes in the cytoplasm of the cell
What is the purpose of transcription. -APEXA. It is the last step in protein synthesis.B. It is the first step in protein synthesis.C. It is the first step in DNA synthesis.D. It is the last step in DNA synthesis?
I have no idea
Why is accurate initiation of protein synthesis important?
It is the first step in creating proteins.
Which is the second step in writing a synthesis paragraph?
The second step in writing a synthesis paragraph is reading trough to eliminate any mistake.
What step of the protein synthesis process would be disrupted if someones diet was nutricienally deficient in proteins?
there will not be enough amount of amino acids present in the protein deficient food, hence there will not be enough protein synthesis.
Inhibitor of protein synthesis?
In prokaryotes tetracycline, chloremphenicol can inhibit protein synthesis. Puromycin is an antibiotic that inhibit both prokaryotic and eukaryotic protein synthesis. Each antibiotics has specific mode of action where it inhibits by binding, for example Chloremphenicol block the peptidyl transfer step.
