mRNA stands for messenger RNA.
mRNA is a type of RNA (ribonucleic acid) molecule that carries genetic information from the DNA (deoxyribonucleic acid) in the cell nucleus to the ribosomes in the cytoplasm, where it serves as a template for protein synthesis.
During the process of transcription, which occurs in the nucleus, the DNA double helix is unwound, and an enzyme called RNA polymerase synthesizes a complementary strand of RNA based on the sequence of the DNA template. This resulting mRNA molecule is then modified and processed before leaving the nucleus and entering the cytoplasm.
In the cytoplasm, mRNA provides the code for the sequence of amino acids that make up a specific protein. The ribosomes, read the mRNA molecule and, using a process called translation, generate a chain of amino acids that folds into a functional protein.
mRNA is a crucial component in the central dogma of molecular biology, which explains the flow of genetic information from DNA to mRNA to protein. It plays a vital role in protein synthesis and gene expression, allowing cells to produce the specific proteins needed for various cellular processes.
