In bacteria, three main types of … WebThe RNA primer does contain uracil but it is actually removed and replaced by DNA by enzymes including a nuclease and a polymerase. There are no DNA primers in humans. …
Web14 mei 2016 · To solve this problem, replication process on 2 strands is performed in a semi-discontinuous manner. On the 3’-5’ parent strand, nascent strand is synthesized continuously, requires only one primer to form leading product. The 3’-5’ template strand therefore called leading template. Web30 dec. 2024 · DNA replication is similar to transcription in its most general idea: a polymerase enzyme reads a strand of DNA one nucleotide at a time, it takes a random …
