WebApr 8, 2024 · messenger RNA (mRNA), molecule in cells that carries codes from the DNA in the nucleus to the sites of protein synthesis in the cytoplasm (the ribosomes). The … WebJan 8, 2024 · The mRNA is made in the nucleus and sent to the ribosome, like all RNA. Once it gets there, the mRNA bonds with the ribosome, which reads the mRNA’s nitrogen base sequence. Every three-bond sequence of mRNA relates to a specific amino acid, a “building block” of a protein.

Once made, mRNA travels away from the nucleus to the cytoplasm. In the cytoplasm, ribosomes read the base sequence of the mRNA and recruit corresponding amino acids.
WebThe pre-mRNA has to go through some modifications to become a mature mRNA molecule that can leave the nucleus and be translated. These include splicing, capping, and addition … WebSep 6, 2024 · In the case of vaccines, the mRNA codes for a piece of a viral protein known as an antigen. Once translated, the antigen triggers an immune response to help confer protection against the virus ...
