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.
What else can I help you with?
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.
Which process is the frist step of protein synthesis?
Transcription
Where is the first step of protein synthesis occur?
on the ribosomes in the cytoplasm of the cell
What is the degradation and synthesis of protein called?
Protein degradation is called proteolysis, which is the breakdown of proteins into amino acids or smaller peptide fragments. Protein synthesis is the process of creating new proteins using the genetic information encoded in DNA through transcription and translation.
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.
What is the second part of protein synthesis?
The second part of protein synthesis is translation, where the messenger RNA (mRNA) is decoded by ribosomes to assemble a specific amino acid sequence and form a protein. This process occurs in the cytoplasm of the cell.
Which of these is a step in protein synthesis?
Translation, which is the process of synthesizing proteins from mRNA using ribosomes and tRNA, is a step in protein synthesis. During translation, the ribosome reads the codons on the mRNA and binds the appropriate amino acids carried by tRNA molecules to assemble the protein chain.
3 steps of protein synthesis?
Transcription: DNA is used as a template to make a complementary RNA molecule. Translation: The mRNA produced during transcription is used to synthesize a specific protein by ribosomes. Protein folding and modification: The newly synthesized protein undergoes folding and post-translational modifications to become functional.
Describe the role of DNA and genes in protein synthesis.?
The role Of DNA and genes in protein synthesis is to create proteins through its multi-step process of transcription and translation which results in the formation of proteins.
How is protein synthesis related to gene expression?
Protein synthesis is the process where proteins are produced based on the information encoded in genes. Gene expression involves the process where the information in a gene is used to produce a functional product, such as a protein. Protein synthesis is a key component of gene expression, as it is the step where the genetic information in the gene is translated into a functional protein.
