You Make Two Different Kinds of Metagenomes-One to Measure Diversity

question 38

Essay

You make two different kinds of metagenomes-one to measure diversity from only 16S rRNA DNA sequences, and one from the entire DNA that does not require amplification. You observe 1,000 times more 16S rRNA gene sequences from the first metagenome than the second. However, you find that the number of species according to the 16S rRNA gene sequences is 10 times more in the second metagenome than the first. Why?

Examples are specific instances or items that are representative of a general case or category, often used to illustrate a point or explain a concept.

Normally Distributed

A distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean.

Standard Deviation

A measure of the dispersion or spread of a set of numbers, indicating how much the individual numbers differ from the mean of the set.

Mean

The average of a set of numbers, calculated by dividing the sum of the values by the count of numbers.
