instrumental for the RNA World Hypothesis ("Sidney Altman: The RNA World").

The RNA was able to spontaneously form under natural processes‚ which eventually replicated into all sorts of life. This paper will analyze the theoretical and experimental support for this hypothesis and comment on the plausibility of the RNA World Hypothesis. The RNA World theory is

understanding of hypothesis testing. The textbook explained the aspects and steps of hypothesis testing in a legible fashion‚ while the video helped demonstrate a real-life application. I learned from the text that hypothesis testing is a “Procedure for deciding whether the outcome of a study (results from a sample) supports a particular theory or practical innovation (which is thought to apply to a population)” (Aron A.‚ Aron‚ E.‚ and Coups‚ 2011‚ p. 145).
