WebIt is important to note that elongation is a dynamic process that changes depending on how heterogeneous the DNA being transcribed is in terms of the sequence. As a result, it should come as no surprise that the composition of the elongation complex changes as a gene is transcribed. The transcription elongation process is controlled by stopping ...

WebDec 24, 2024 · Elongation During elongation, an enzyme called DNA polymerase adds DNA nucleotides to the 3′ end of the newly synthesized polynucleotide strand. The template strand specifies which of the four DNA nucleotides (A, T, C, or G) is added at each position along the new chain. WebJun 8, 2024 · Elongation RNA Polymerase II is a complex of 12 protein subunits. Specific subunits within the protein allow RNA Polymerase II to act as its own helicase, sliding clamp, single-stranded DNA binding protein, as well as carry out other functions.
WebMar 1, 2024 · Chain elongation occurs when the σ subunit dissociates from the DNA strand, allowing the growing RNA strand to separate from the DNA template strand. This is facilitated by the core enzyme (see Figure 2). Image Source : Wikipedia.
