2. Bacterial transcription - Wikipedia

   en.wikipedia.org/wiki/Bacterial_transcription

   Bacterial transcription is the process in which a segment of bacterial DNA is copied into a newly synthesized strand of messenger RNA (mRNA) with use of the enzyme RNA polymerase. The process occurs in three main steps: initiation, elongation, and termination; and the result is a strand of mRNA that is complementary to a single strand of DNA.

3. Transcription (biology) - Wikipedia

   en.wikipedia.org/wiki/Transcription_(biology)

   Only one of the two DNA strands serves as a template for transcription. The antisense strand of DNA is read by RNA polymerase from the 3' end to the 5' end during transcription (3' → 5'). The complementary RNA is created in the opposite direction, in the 5' → 3' direction, matching the sequence of the sense strand except switching uracil ...

4. Primary transcript - Wikipedia

   en.wikipedia.org/wiki/Primary_transcript

   The steps contributing to the production of primary transcripts involve a series of molecular interactions that initiate transcription of DNA within a cell's nucleus. Based on the needs of a given cell, certain DNA sequences are transcribed to produce a variety of RNA products to be translated into functional proteins for cellular use.

5. Eukaryotic transcription - Wikipedia

   en.wikipedia.org/wiki/Eukaryotic_transcription

   Eukaryotic transcription occurs within the nucleus where DNA is packaged into nucleosomes and higher order chromatin structures. The complexity of the eukaryotic genome necessitates a great variety and complexity of gene expression control. Eukaryotic transcription proceeds in three sequential stages: initiation, elongation, and termination. [1]

6. Translation (biology) - Wikipedia

   en.wikipedia.org/wiki/Translation_(biology)

   The transcription-translation process description, mentioning only the most basic "elementary" processes, consists of: production of mRNA molecules (including splicing), initiation of these molecules with help of initiation factors (e.g., the initiation can include the circularization step though it is not universally required),

7. Initiation factor - Wikipedia

   en.wikipedia.org/wiki/Initiation_factor

   Translation initiation is sometimes described as three step process which initiation factors help to carry out. First, the tRNA carrying a methionine amino acid binds to the small subunit of ribosome, then binds to the mRNA, and finally joins together with the large subunit of ribosome. The initiation factors that help with this process each ...

8. Eukaryotic translation - Wikipedia

   en.wikipedia.org/wiki/Eukaryotic_translation

   Recent structural biology results also indicated that a second eIF4A protein can simultaneously associate with the initiation complex, specifically interacting with eIF3. [2] [3] The poly(A)-binding protein (PABP) also associates with the eIF4F complex via eIF4G, and binds the poly-A tail of most eukaryotic mRNA molecules. This protein has been ...

9. Mature messenger RNA - Wikipedia

   en.wikipedia.org/wiki/Mature_messenger_RNA

   Unlike the eukaryotic RNA immediately after transcription known as precursor messenger RNA, [1] mature mRNA consists exclusively of exons and has all introns removed. The Maturation of mRNA. Mature mRNA is also called "mature transcript", "mature RNA" or "mRNA". The production of a mature mRNA molecule occurs in 3 steps: [2] [3] Capping of the ...
