What is the primary product of transcription?

The primary product of transcription is messenger RNA (mRNA). Transcription is the process by which genetic information stored in DNA is copied into RNA. During this process, a specific segment of DNA is unwound and used as a template for synthesizing mRNA. The mRNA molecule contains the complementary sequence to the DNA template, serving as a template for translation, which is the subsequent process that synthesizes proteins.

Understanding this process highlights the role of mRNA as a crucial intermediary in the flow of genetic information from DNA to protein synthesis. While proteins, DNA, and transfer RNA (tRNA) are all important in cellular processes, they are not the direct products of transcription. DNA serves as the template, and tRNA plays a role in translation, aiding in the assembly of amino acids into proteins based on the sequence encoded in the mRNA.
