DNA Transcription Process Explained - Template Strand to mRNA Synthesis #3702042 (License: Personal Use)

The image depicts a double-helical DNA molecule partially unwound, with one strand labeled “DNA template strand” serving as the blueprint for mRNA synthesis. A growing mRNA strand is shown forming through complementary base pairing-adenine (A) pairs with uracil (U) instead of thymine (T), while cytosine (C) pairs with guanine (G). Nucleotides are color-coded to emphasize specificity during transcription, illustrating the central dogma’s first step from DNA to RNA.

Used in biology education resources, genetics textbooks, and molecular biology webpages to explain transcription; matches user intent for learning how genes are expressed at the molecular level.
