To transfer codes for the cell's proteins.
Molecules of Ribonucleic Acid (RNA) carry the instructions for assembling proteins out of the cell nucleus. Without this type of molecule, the cell cannot survive.
mRNA
Transcription occurs in the nucleus of a cell. Here, the enzyme RNA polymerase reads the DNA sequence and synthesizes a complementary mRNA molecule. Once transcribed, the mRNA can then move to the cytoplasm for translation into a protein.
Transcription produces a molecule called mRNA (messenger RNA). This molecule carries the genetic information from DNA in the cell's nucleus to the ribosomes in the cytoplasm. mRNA serves as the template for protein synthesis during translation.
mRNA does not go to the Golgi apparatus. mRNA is a molecule that carries genetic information from the cell's nucleus to the ribosomes where proteins are synthesized. The Golgi apparatus is mainly involved in modifying, sorting, and packaging proteins for secretion or for use within the cell.

mRNA
The mRNA molecule encodes the protein product in the cell for translation. It is a double stranded, base-paired, ribonucleic acid that typically encodes a single gene, or protein, product.
mRNA is not a direct copy of DNA, but it is a molecule that carries genetic information from DNA to the ribosomes in the cell where proteins are made.
The attachment of a mRNA molecule to a ribosome takes place in the cytoplasm of a cell. The ribosome binds to the mRNA at the start codon to initiate protein synthesis. This process is essential for translating the genetic information encoded in the mRNA into a specific protein.
mrna is made by RNA polymers, using DNA as a template.
Polyadenylation is a process in which a poly(A) tail is added to the 3' end of a newly synthesized mRNA molecule. This poly(A) tail helps to stabilize the mRNA molecule and plays a role in the export of the mRNA from the nucleus to the cytoplasm for translation. Polyadenylation also signals the termination of transcription.
Transcription occurs in the nucleus of a cell. Here, the enzyme RNA polymerase reads the DNA sequence and synthesizes a complementary mRNA molecule. Once transcribed, the mRNA can then move to the cytoplasm for translation into a protein.
Chaperone proteins function to move molecules (such as mRNA from the nucleus to the cytoplasm). They are also called heat shock proteins because they protect the molecule (mRNA) from heat which would degrade the molecule (mRNA) and ruin the process (such as transcription).
Transcription produces a molecule called mRNA (messenger RNA). This molecule carries the genetic information from DNA in the cell's nucleus to the ribosomes in the cytoplasm. mRNA serves as the template for protein synthesis during translation.
Polyadenylation takes place in the cell nucleus after a pre-mRNA molecule has been transcribed but before it is processed into a mature mRNA molecule. During polyadenylation, a string of adenine nucleotides, known as a poly(A) tail, is added to the 3' end of the pre-mRNA.
Once mRNA leaves the nucleus and enters the cytoplasm of a eukaryotic cell, it serves as a template for protein synthesis during translation. Ribosomes in the cytoplasm "read" the mRNA sequence and use it to assemble amino acids into a polypeptide chain, ultimately leading to the production of a specific protein.
