Page 2: The Transcription Process

This page details the intricate process of transcription, where DNA information is converted into messenger RNA. The process begins with DNA unzipping and involves RNA polymerase attaching to a promoter sequence.

Example: RNA polymerase builds mRNA by adding complementary RNA nucleotides one at a time along the DNA template strand.

Highlight: In eukaryotes, mRNA undergoes splicing to remove non-coding regions called introns before leaving the nucleus through nuclear pores.

Definition: Key differences between RNA and DNA include:

• RNA uses uracil instead of thymine
• RNA contains ribose sugar while DNA has deoxyribose
• RNA is typically single-stranded while DNA is double-stranded
