Mrna (Noun)
Meaning
The template for protein synthesis; the form of RNA that carries information from DNA in the nucleus to the ribosome sites of protein synthesis in the cell.
Classification
Nouns denoting substances.
Examples
- The sequence of nucleotides in the mRNA molecule determines the sequence of amino acids in the protein being synthesized.
- mRNA is synthesized in the nucleus through a process called transcription, where a segment of DNA serves as a template.
- The mRNA molecule then travels out of the nucleus and into the cytoplasm, where it is translated into a protein.
- During translation, the sequence of nucleotides in the mRNA is read by the ribosome, which assembles the corresponding amino acids into a polypeptide chain.
- The process of transcription and translation allows cells to use the genetic information stored in DNA to synthesize specific proteins, with mRNA serving as the crucial intermediate molecule.
