The discovery of DNA stands as one of the most monumental achievements in the realm of science. Today, our deeper understanding of DNA structure has unveiled answers to questions that have puzzled us for ages. The Central Dogma elucidates how DNA encodes proteins through three essential stages: replication, transcription, and translation. What Is Transcription? Transcription is the initial step in gene expression. It involves the conversion of DNA information into RNA. Here’s how it works: Template Strand: During transcription, only one strand of DNA—the template strand—is copied. This template strand serves as a guide for synthesizing a complementary RNA molecule. RNA Synthesis : The enzyme responsible for transcription is RNA polymerase. It binds to a specific DNA region called the promoter and catalyzes the synthesis of RNA in the 5’ to 3’ direction along the template strand. The newly formed RNA strand is called mRNA (messenger RNA). Purpose o
