"WebTranscription is the first step in gene expression. It involves copying a gene's DNA sequence to make an RNA molecule. Transcription is performed by enzymes called RNA polymerases, which link nucleotides to form an RNA strand (using a DNA strand as a template). Transcription has three stages: initiation, elongation, and termination. " - How many molecules of rna are found in hiv

WebIn fact, the suppressive effect of an asRNA largely depends on its ability to form dsRNA. Normally, RNA molecules are present in the cytoplasm of a cell as single-stranded transcripts. If the cell finds molecules of dsRNA, for example, asRNA:mRNA duplex, it uses Dicer to cleave them into siRNA fragments containing ∼21 base pairs.
