To isolate DNA from a cell pellet, a student is performing an extraction using phenol and chloroform. The cells were lysed with 0.5mL of lysis buffer. 0.5mL extraction solution, consisting of phenol:chloroform:isoamyl alcohol (25:24:1), was added to the lysate. The sample was centrifuged at high speed for five minutes. The liquid in the tube was separated into three phases after centrifugation (see diagram).

In which layer will nucleic acids (RNA and DNA) be found?
