Answer: Singing , as whistleing does not even involve your larynx
Explanation:
Prokaryotes have no cell nucleus and no membrane enclosed organelles. Prokaryotic DNA can be found in a coiled loop floating in the cytoplasm in a region called the nucleoid (meaning nucleus-like). In other words, the nucleoid is the area in a prokaryotic cell where DNA is located.
In eukaryotic cells, DNA is located in the nucleus, the mitochondria and the chloroplasts (occuring only in plants and some protists). The nucleus contains most DNA. It is present in this compartment in the form of linear chromosomes that together constitute the genome.
Answer:RNA polymerase – makes a molecule of RNA from an RNA template
Explanation: RNA polymerase is an enzyme that catalyzes the copying of a DNA sequence into an RNA sequence during transcription. RNA polymerase uses a DNA template for the synthesis of an RNA strand. RNA polymerase is also called DNA-dependent RNA polymerase. During transcription, DNA helicase unwinds the double helix of the DNA while the RNA polymerase catalyzes the synthesis of an RNA strand from the DNA.
