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.
In the transcription step, nucleotide sequence of the gene in the DNA strand is transcribed into RNA. This first step is highly similar to the DNA replication except the result is a strand on RNA in protein synthesis.The DNA strand being dismantled with DNA helicase enzyme, RNA polymerase is attached at the specific place of the start of the gene known as promoter, and RNA strand is synthesized along the gene.his first step is highly similar to the DNA replication except the result is a strand on RNA in protein synthesis.
