About this unit
This unit is part of the Biology library. Browse videos, articles, and exercises by topic.Get an overview of the "central dogma" of molecular biology! Learn how a gene's DNA is copied into RNA (transcription), which is then "decoded" to specify the amino acid sequence of a protein (translation).

Transcription is the first step in gene expression. It involves copying, or transcribing, the DNA sequence of a gene into the similar "alphabet" of RNA nucleotides. Learn more about this crucial cellular process.
