The step of protein synthesis that occurs in the nucleus is transcription. Transcription is the process of copying the genetic code from DNA into RNA. The RNA molecule that is produced during transcription is called messenger RNA (mRNA). mRNA then travels to the cytoplasm, where it is translated into a protein.
In transcription, the DNA double helix opens up at a specific location called the promoter. A protein called RNA polymerase binds to the promoter and begins to move along the DNA strand, unzipping the helix as it goes. RNA polymerase then uses the exposed DNA strand as a template to synthesize a complementary RNA strand. This RNA strand is the mRNA molecule.
Once the mRNA molecule is complete, it separates from the DNA and travels to the cytoplasm. In the cytoplasm, the mRNA molecule binds to a ribosome. The ribosome then reads the mRNA molecule and uses the information to assemble a protein molecule. The protein molecule is then released from the ribosome and can go on to perform its function in the cell.
Here are the steps of transcription in detail:
Initiation: RNA polymerase binds to the promoter region of DNA.
Elongation: RNA polymerase moves along the DNA strand, unzipping the helix and synthesizing a complementary RNA strand.
Termination: RNA polymerase reaches a termination sequence in the DNA and stops synthesizing RNA.
The mRNA molecule that is produced during transcription is a single-stranded molecule that contains the same information as the original DNA strand. However, the mRNA molecule is modified in a few ways. First, the 5' end of the mRNA molecule is capped with a group of nucleotides called a 5' cap. The 5' cap helps to protect the mRNA molecule from degradation and helps it to bind to the ribosome. Second, the 3' end of the mRNA molecule is polyadenylated, which means that it is added to a long chain of adenine nucleotides. The polyadenylation tail helps to stabilize the mRNA molecule and helps it to be transported to the cytoplasm.
Transcription is a complex process that is essential for protein synthesis. It is the first step in the process of converting genetic information into a functional protein molecule.

Who kept the second step on moon?
Neil Armstrong kept the first step then it is sure that he took the second step also. JOKE
Who as the first person to step on the moon?
Niel Armstrong was the first to step on the moon.
Second man to step on the moon?
The second man to step on the moon was Edwin Aldrin.
When was One Small Step... created?
One Small Step... was created in 2005-10.
Where is the first step of protein synthesis occur?
on the ribosomes in the cytoplasm of the cell
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
Which process is the frist step of protein synthesis?
Transcription
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
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
Why is accurate initiation of protein synthesis important?
It is the first step in creating proteins.
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.
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.
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.
What is the multi step process that includes the linking of amino acids the transcription of DNA into mRNA and translation called?
protein synthesis
Where in a eukaryotic cell does the process of transcription take place?
Transcription occurs in the cell nucleus and where DNA is housed. Transcription is the first step of gene expression, in which a particular segment of DNA is copied into RNA by the enzyme RNA polymerase.
