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.
When RNA's base sequence is used to determine the base sequence of a new strand of DNA, that is called reverse transcription. This is because the process is the reverse of tr â¦ anscription, which involves copying the base sequence of DNA to form RNA, including messenger RNA (mRNA).Answered. In Cell Biology (cytology).he type of RNA that copies DNA is known as the messenger RNA or mRNA. There are other types of RNA these include the transfer RNA (tRNA), and the ribosomal (rRNA).
