Definition
Messenger RNA (mRNA) is a type of RNA that transcribes genetic information from DNA and carries it to the ribosomes, where it serves as a template for protein synthesis. It plays a crucial role in the process of gene expression by facilitating the translation of genetic code into functional proteins.
Summary
Messenger RNA (mRNA) is a vital molecule in the process of gene expression. It serves as a messenger that carries genetic information from DNA in the nucleus to the ribosomes in the cytoplasm, where proteins are synthesized. The process begins with transcription, where a specific segment of DNA is copied into mRNA. This mRNA then undergoes processing before it is translated into a protein by ribosomes. Understanding mRNA is crucial for grasping how genes are expressed and how proteins are made, which are essential for all biological functions. mRNA plays a significant role in various applications, including vaccine development and gene therapy, highlighting its importance in modern science and medicine.
