question 80

Multiple Choice

• A) translational control in cytoplasm after mRNA leaves the nucleus and before protein is produced.
• B) transcriptional control in the nucleus based on which genes are transcribed and how fast they are transcribed.
• C) posttranscriptional control in the nucleus after DNA is transcribed, including the speed with which mRNA leaves the nucleus.

Definitions:

Test Statistic

A value calculated from sample data during a hypothesis test used to decide whether to reject the null hypothesis.

Kruskal-Wallis Test

A nonparametric test used to compare three or more groups based on ranks of data points rather than means or medians.

One-tail

One-tail refers to one-sided tests in hypothesis testing where the critical area of a distribution is one-sided, either to the right or left, focusing on a specific direction of interest.

Two-tail

A term used in statistical tests where the critical region is split between both ends of the distribution, testing for either significantly greater or lesser outcomes than the expected value.
