Picaridin can be used on human skin or clothing to repel mosquitoes, biting flies, ticks, fleas, and chiggers. These products may be pump sprays, liquids, aerosols, or wipes.
Transcription is carried out by a DNA-dependent RNA polymerase that copies the sequence of a DNA strand into RNA. To begin transcribing a gene, the RNA polymerase binds to a sequence of DNA called a promoter and separates the DNA strands.
Transcription. RNA is copied from DNA in a process called. transcription. . During Transcription. The enzyme RNA polymerase binds to DNA and separates the 2 DNA strands. RNA polymerase builds a strand of RNA using one strand of DNA as the template.The DNA is transcribed into RNA following base-pairing rules except that uracil binds to adenine.he enzyme RNA polymerase binds to DNA and separates the 2 DNA strands.
