To make a protein, a cell goes through two processes, the first one is transcription and the second is translation.
In the first stage, DNA helicase unwinds and unzips the two strands of a DNA double helix. Then DNA polymerase comes in and helps make a complementary strand called messenger RNA of mRNA. this mRNA is then cut up to the bare essentials, thus containing pretty much only the nucleotides coding for genes. Splicosomes are the molecules that do this cutting, known as splicing, which then makes the mRNA ready for action. The mRNA then travels outside of the nucleus, and finds a transfer RNA of tRNA molecule.
The next step is translation, in which the actual building of the protein takes place. First off, the mRNA molecule is floating around, until it meets a ribosome. This ribosome is the site at which this mRNA will meet a tRNA molecule, containing a nucleotide sequence complementary to that of the mRNA. This tRNA has this nucleotide sequence at one end, and an amino acid on the other end. This amino acid is then put into the ribosome, into the A site of the ribosome. It then moves to the P site, where the polypeptide chain, or building of the protein is actually taking place. This amino acid is then adjoined to the chain, and is then part of the protein molecule. Once all of the necessary amino acids are joined in, the protein moves to the E site, where it exits the ribosome. This molecule is then complete, and will then proceed to the part of the cell where it is needed, and will start to function.
What else can I help you with?
what organelle is in charge of making protein?
The ribosomes.
What mrna codon starts the making of protein?
The mRNA codon that starts the making of a protein is AUG. This codon codes for the amino acid methionine and also serves as the start codon that initiates protein synthesis.
What does a protein phosphatase actually do to end a signal transduction?
Protein phosphates turn off signal transduction pathways by removing the phosphate groups from the protein kinase, making them reusable and making the kinase inscribe stopping the signal transduction pathway.
How can mutation affect protein synthesis in cell?
Mutations can make the protein synthesise incorrectly making diseases or weak parts in your body. Mutations can affect protein synthesis in cells by affecting the protein, messing up the whole DNA sequence and making the organism different from other average organisms.
The first step in making a protein is to make a copy of what?
The first step in making a protein is to make a copy of the gene that codes for that protein. This copy, known as messenger RNA (mRNA), is made through a process called transcription, where the DNA sequence of the gene is converted into a complementary RNA sequence.
Do nucleic acids hold polymers for making protein?
No, nucleic acids code for the making of protein, they do not contain the monomers of protein manufacturing.
Why shouldn't you fall into a trap of buying expensive protein supplements?
They are just as effective as making your own protein shake at home.
Is protein a mineral?

On Pokemon diamond what level does Pichu evolve?
You either keep training it, or make it real happy, making happy by giving it protein and such.
The Process of making protein is called?
The process of making protein is called protein synthesis. It involves the transcription of DNA into messenger RNA (mRNA) and the subsequent translation of mRNA into a polypeptide chain of amino acids.
How was this model of protein synthesis similar to the real process?
The model of protein synthesis accurately represented the steps and components involved in the real process, such as the role of mRNA, tRNA, ribosomes, and amino acids in building a protein.
