WebMay 16, 2024 · The flow of information follows a conventional pathway: dsDNA → mRNA → protein, with a DNA-dependent RNA-polymerase producing the mRNA and the host ribosome producing the protein. The genome replication, dsDNA → dsDNA, requires a DNA-dependent DNA-polymerase from either the virus or the host cell. dsDNA. WebRNA polymerase binds to a sequence of DNA called the promoter, found near the beginning of a gene. Each gene (or group of co-transcribed genes, in bacteria) has its own promoter. Once bound, RNA polymerase separates the DNA strands, providing the single-stranded … Transcription uses one of the two exposed DNA strands as a template; this strand is … Both RNA and DNA are synthesized in the cell by enzymes called polymerases …

WebMar 25, 2024 · RNA polymerase is a multi-unit enzyme that synthesizes RNA molecules from a template of DNA through a process called transcription. The transcription of … WebDNA Polymerase reads from the 3’ to 5’ in one strand. In order to make the other strand it adds nucleotides in the 3’ end. For example, if the top strand is from 5’ to 3’, the polymerase simply adds nucleotides to the 3’ end since the strands are anti parallel. [deleted] • 3 yr. ago DearFutureDoctor • 3 yr. ago
