Questions and Answers

What is the 16s ribosomal gene used for in analyzing microbial populations?

To categorize bacteria to at least the family level (correct)
To determine the size of bacterial ribosomes
To identify the order of A, T, G, and C's in bacteria
To extract DNA from a microbial sample

What is the most common method for sequencing the 16s ribosomal gene?

Amplifying the gene through PCR and then sequencing the amplified genes (correct)
Using established databases to identify bacterial species
Analyzing the conserved regions of the gene
Directly comparing microbial populations

What factors contribute to the colonization of microbiota in humans early in life?

Maternal diet and weaning
Parental factors, neonatal factors, and postnatal factors
Geographical location, family members, and host interactions
Mode of delivery, gestational age, and feeding (correct)
