Questions: The field of pharmacogenomics is a means to correlate a person's genetic background with drug treatments. This field relies on an analysis of frameshift mutations complete genome sequence SNPs ribozymes

The answer is the third one: SNPs.

Explanation for each option:

1. Frameshift mutations: These are genetic mutations caused by insertions or deletions of a number of nucleotides in a DNA sequence that is not divisible by three. While they can affect drug response, pharmacogenomics primarily focuses on more common genetic variations.

2. Complete genome sequence: While having a complete genome sequence can provide comprehensive information, pharmacogenomics typically focuses on specific genetic variations that are more practical and cost-effective to analyze.

3. SNPs (Single Nucleotide Polymorphisms): These are the most common type of genetic variation among people. SNPs can influence how individuals respond to drugs, making them a primary focus in pharmacogenomics for correlating genetic background with drug treatments.

4. Ribozymes: These are RNA molecules that can catalyze specific biochemical reactions, similar to protein enzymes. They are not directly related to the genetic variations studied in pharmacogenomics.

In summary, pharmacogenomics primarily relies on the analysis of SNPs to understand how genetic differences affect individual responses to drugs.
