Horizontal Gene Transfer in Archaea

question 29

Multiple Choice

Horizontal gene transfer in Archaea

• A) is infrequent in nature and therefore difficult to use for genetic studies in the laboratory.
• B) has not been documented, thus all genetic studies of archaea are done via genomic sequencing.
• C) frequently occurs in nature and has been used to perform genetic studies in the laboratory as well.
• D) frequently occurs in nature, but there are very few laboratory studies because archaea do not cause human disease.

Definitions:

Significance Test

A statistical method used to determine if there is a significant difference between groups or conditions, typically by comparing p-values to predefined significance levels.

Outliers

Observations in a dataset that are significantly different from the other data points, often indicating measurement error, variability in measurement, or a novel discovery.

Alternative Hypothesis

In statistics, the hypothesis that proposes there is a difference between two or more groups or variables, contrasted with the null hypothesis.

Two-sided Test

A statistical test designed to determine if there is a significant difference between a parameter and a specific value, in either direction.
