you could alwayz just record it down and re-listen to it and take down notes. taking down notes doesn't hurt, it doesn't matter how much or how little you write. Every one has their own style of taking notes, as long as you understand and that your writing is readable (so the nxt time you read it, you actualli know what you have written) , do it whaeva way suits you the best !!

hey DNA is mostly found in the chromosomes. RNA (ribonucleic acid) is found throughout the cell. Procaryotic cells contain no membrane-bound organelles. They therefore have no nucleus as such, and the nuclear material is one long DNA strand. Eucaryotic contain membran-bound organelles and have nuclei which contain more than one chromosome. i hope this helps btw, what do u mean by 'A-level biology'?
