мРНК, or messenger RNA, is a type of nucleic acid that plays a crucial role in the process of protein synthesis within cells. It is synthesized from DNA and carries genetic information from the nucleus to the ribosomes, where proteins are made. This process is essential for the functioning and development of all living organisms. Once мРНК reaches the ribosomes, it serves as a template for assembling amino acids into proteins. Each sequence of three nucleotides in мРНК corresponds to a specific amino acid, guiding the ribosome in building the correct protein. This process is vital for cellular functions and overall organism health.
