The process of synthesizing RNA from a DNA template.

An enzyme that synthesizes RNA by binding to DNA.

A DNA sequence where RNA polymerase binds to initiate transcription.

The direction in which RNA is synthesized during transcription.

The orientation where RNA runs in the opposite direction to the DNA template strand.

The flow of genetic information from DNA to RNA to protein.

The DNA strand that has the same sequence as the RNA produced during transcription (except for T/U).

An enzyme that synthesizes RNA from a DNA template in prokaryotes.

A protein that enables RNA polymerase to recognize the promoter region of DNA.

The segment of DNA that is transcribed into RNA, extending from promoter to terminator.

The complete RNA polymerase complex including the core enzyme and the σ factor.

A specific sequence of DNA where RNA polymerase binds to initiate transcription.

snRNAs facilitate splicing by base pairing with introns to align exons.

The process of removing introns and joining exons to form mature mRNA.

Eukaryotes transcribe RNA in the nucleus before mRNA exits for translation.

Prokaryotes lack a nucleus; transcription and translation occur simultaneously. Eukaryotes separate these processes.

Pre-mRNA undergoes modifications (like splicing) to become mature mRNA.

A sequence of seven nucleotides centered around ten nucleotides upstream of the mRNA start site.

A sequence located about 35 nucleotides upstream of the mRNA initial base.

The phase where RNA polymerase synthesizes mRNA from the DNA template post-initiation.

The building blocks used by RNA polymerase to add nucleotides to the growing RNA strand.

The process where the DNA helix unwinds in a localized area during transcription.

The byproduct released when RNA polymerase adds a nucleotide to the growing RNA chain.

The strand of DNA that serves as a guide for RNA synthesis.

RNA is synthesized in the 5' to 3' direction during transcription.

In RNA, 'G' pairs with 'C', 'C' pairs with 'G', 'T' pairs with 'A', and 'A' pairs with 'U'.

The stage of transcription where RNA polymerase elongates the RNA strand.

A specific sequence in DNA that signals the end of RNA synthesis.

After transcription, the DNA strands re-form their double helix structure.

Enzyme responsible for unwinding DNA and synthesizing RNA during transcription.

The overall process of synthesizing RNA from a DNA template.

The process where RNA polymerase binds to the promoter and begins RNA synthesis.

The stage in transcription where RNA polymerase adds RNA nucleotides, elongating the RNA strand.

The DNA strand that RNA polymerase uses as a guide to synthesize RNA.

The end of transcription when RNA polymerase detaches from the DNA and releases RNA.

A protein that may play a role in terminating transcription by helping release RNA and RNA polymerase.

Refers to the orientation of nucleotides in RNA and DNA; crucial for understanding transcription direction.
