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 is the biochemical process of transferring the information in a DNA sequence to an RNA molecule. The RNA molecule can be the final product, or in the case of messenger RNA (mRNA), it can be used in the process of translation to produce proteins.
