Abstract Oxidation was found for primary alcohol. When 6 drops of potassium dichromate and 1 drop of concentrated sulfuric acid were added to 1-pentanol‚ the color of 1-pentaol turned into dark green. In second experiment‚ precipitation was found when 6 drops of 2‚4-dinitrophenylhydrazine were added to both 5 drops of benzaldehyde and 5 drops of acetophenone. Based on these data‚ it is possible to find alcohol by oxidation and aldehyde by observing precipitation Introduction This experiments

Jazz has been called‚ among other things‚ America’s "only original form‚" showing it’s clear cultural roots in America.

RESULTS AND DISCUSSION In the Iron (II) - Silver Ions System the reaction had a balance chemical equation of Fe2+ + Ag+ Fe3+ + Ag(S). The process if centrifugation is used in this part of the experiment to be able to separate the supernatant and the precipitate. And the supernatant will be used to test for the presence of Fe2+‚ Ag+ and Fe3+ in the solution. Results showed that there is a positive presence for FE 2+‚ Fe3+ and Ag+ because of the visible change of color of Prussian blue precipitate

CRISPR-Cas9 is a method of gene editing that provides researchers with a way of precisely targeting a specific string of DNA. CRISPR is a sequence of repeated DNA located in the genomes of bacteria that are used in immune systems to help protect our bodies from infecting viruses. This method involves the use of an enzyme known as Cas9 and a guide RNA. A virus’s DNA becomes spacers in the CRISPR sequence when the new virus infects the bacterium. This sequence will then begin the process of transcription
