The major steps of protein synthesis are:
1. Transcription
-before a protein can be synthesized, the DNA information or code must first be copied or transcribed to a type of RNA called mRNA (messenger RNA). Bothe the codes in DNA and mRNA are carried as units called codons.
2. Translation
-in the ribosome, the code carried by the mRNA is translated into a sequence of amino acids that will form the protein molecule dictated by the DNA.
Here's a quick and dirty explanation, since it takes too long to teach it formally. Be careful because some of the items are listed out of order.
Transcription: nucleus
steps of proteins synthesis are:
1-TRANSLATION
A= mRNA attaches to a ribosome
B= tRNA approaches the mRNA and every 3 bases on the mRNA are paired with a matching tRNA call codon
C= the amino acid is removed from the tRNA and the tRNA detaches from the mRNA
D= the amino acid are bonded together to make a protein
2 TRANSCRIPTION
mRNA is formed by bases pairing with one side of the DNA and the mRNA leaves the nucleus to go to the cytoplasm
at the end of the mRNA strands is a stop codon that signals the end of protein synthesis
the protein is released to do work in the organism
Protein synthesis begins with transcription. RNA is coded to create a protein using a single strand of DNA as a template. This strand of RNA now becomes mRNA (messenger RNA) and is composed of introns and exons. The introns are the non-coding segments and will be spliced out. The mRNA will venture out of the nucleus and into the ribosome, where protein synthesis occurs. tRNA (transfer RNA) then bind onto the mRNA to begin a process called translation the coding segments into amino acids. This strand of amino acids forms a protein.
1. In the nucleus, the DNA code is transcribed into a complementary mRNA molecule;
2. mRNA enters the cytoplasm where it associates with a ribosome. The mRNA code is then
translated into a polypeptide chain;
3. The codon AUG signals the start of translation;
4. An activated tRNA brings methionine (the first amino acid) to the ribosome;
5. The tRNA anti-codon binds to the AUG codon on the mRNA;
6. The complex shifts and the next codon is read by another tRNA;.
7. Peptide bonds form between the first two amino acids;
8. The second tRNA accepts the growing polypeptide chain;
9. The process continues until it reaches a STOP codon;
10. The ribosome disassembles and the polypeptide chain is released.
replication, transcription, & translation
Genetic information is copied and transferred to RNA from DNA then RNA and ribosomes made by the nucleolus exit the nucleus through its pores and make more proteins.
step 1: transcription of mRNA from a DNA gene in the nucleus.
step 2: initiation
step 3: elongation
6 steps in the synthesis of proteins
steps of organelles
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.
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
AUGMethionine is specified by the codon AUG, which is also known as the start codon. Consequently, methionine is the first amino acid to dock in the ribosome during the synthesis of proteins.

steps of organelles
The steps in protein synthesis are Transcription, Modification and Packaging, and lastly Translation.
The steps of protein synthesis: Transcription occurs in the nucleus of the cell, where DNA is transcripted into mRNA Translation occurs in the cytoplasm of the cell, where the mRNA is translated into amino acids and forms a protein

The two main steps in protein syntheis are transcriptionand translation. In transcription, the enzyme RNA Polymerase uses a DNA strand as a template to make a transcript of messenger RNA. This transcript is then translated into protein by the ribosome.
If your question is "What is the site of the protein synthesis that occurs in the cytoplasm and on the rough ER?" then the answer is as follows: Protein synthesis occurs in both cases at the ribosomes, which are protein and RNA structures that catalyse the steps of protein synthesis. There are ribosomes free in the cytoplasm and attached to the rough ER. The proteins are processed in the cytoplasm or the ER after synthesis, this involves processes such as folding. The finished proteins are found free in the cytoplasm if they are synthesised by cytoplasmic ribosomes. If they are synthesised on the ER they are transported across the ER membrane into the lumen of the ER and stored in vesicles or released into the interstitial space via secretory vesicles.
Protein synthesis takes place in the ribosomes and also in the Rough Endoplasmic Reticulum (RER).
