Multiple Choice

A scientist has obtained a sequence of a chimpanzee gene and wants to study how it interacts with other genes in a pathway. Which of the following approaches would be most appropriate to identify gene-gene interactions in this context?

Measuring the melting temperature of the DNA sequence

Performing a genetic epistasis analysis using model organisms

Counting the number of exons in the gene

Analyzing the GC content of the gene sequence

Verified step by step guidance

Understand the goal: The scientist wants to identify how the chimpanzee gene interacts with other genes in a biological pathway, which involves studying gene-gene interactions.

Evaluate each approach: Measuring melting temperature relates to DNA stability, counting exons relates to gene structure, and analyzing GC content relates to nucleotide composition; none of these directly reveal interactions between genes.

Recognize that genetic epistasis analysis is a method used to study interactions between genes by observing phenotypic effects when multiple genes are mutated or altered, often using model organisms.

Consider that model organisms provide a controlled system to manipulate genes and observe how changes in one gene affect the function of others, which is essential for identifying gene-gene interactions.

Conclude that performing genetic epistasis analysis using model organisms is the most appropriate approach to study gene-gene interactions in this context.
