  • Transcription


    The process of synthesizing RNA from a DNA template, involving RNA polymerase, which binds to a promoter, elongates the RNA strand, and terminates at a specific sequence.

  • mRNA


    A type of RNA synthesized from DNA during transcription, serving as a template for protein synthesis by conveying genetic information to ribosomes.

  • RNA Polymerase


    An enzyme that synthesizes RNA from a DNA template during transcription, initiating RNA synthesis without needing a primer.

  • Promoter


    A DNA sequence where RNA polymerase binds to initiate transcription.

  • Gene


    A DNA segment containing regulatory and coding sequences that dictate RNA synthesis and protein production.

  • Coding Sequence


    Part of a gene containing the information to produce an RNA molecule, which is then translated into a protein.

  • Terminator


    A DNA sequence signaling RNA polymerase to stop transcription.

  • Primer


    A short nucleic acid sequence that provides a starting point for DNA synthesis by DNA polymerase.

  • Template Strand


    The DNA strand used by RNA polymerase to synthesize a complementary RNA molecule during transcription.
