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.
During transcription the gene (double-stranded DNA) is copied or transcribed into an virtually identical single-stranded messenger RNA molecule (mRNA). In eukaryotes this process occurs in the nucleus. Transcription: 1) RNA polymerase transcribes DNA to make messenger RNA (mRNA).2) The mRNA sequence (dark red strand) is complementary to the DNA sequence (blue strand). Translation: 3) On ribosomes, transfer RNA (tRNA) helps convert mRNA into protein.n eukaryotes this process occurs in the nucleus.
