There are a variety of different types of RNA polymerases that can transcribe different types of RNA. RNA polymerase II, shown here, is responsible for creating messenger RNA (mRNA), which is the main ...

DNA transcription is the vital first step needed for switching on our genes. For a gene to be switched on, it must be acted upon by an enzyme called RNA polymerase. This is a molecular machine which ...

The process of transcription can be visualized by electron microscopy (Figure 1); in fact ... Three different types of RNA polymerase exist in eukaryotic cells, whereas bacteria have only one.

This unwinding of the helix is caused by an enzyme (helicase enzyme). The enzyme RNA polymerase attaches to the DNA in a non-coding region just before the gene. RNA polymerase moves along the DNA ...

After TFs bind to promoter or enhancer regions of the DNA, they interact with other bound TFs and recruit RNA polymerase II ... and development (Table 1). For example, in Drosophila, deletion ...

Announcing a new publication for Acta Materia Medica journal. Single-cell RNA sequencing (scRNA-seq) data from published datasets were obtained to investigate the expression and dysregulation of ...
