What is the primary goal of a genome-sequencing project?

• A. To determine the complete DNA sequence of an organism's genome
• B. To analyze the metabolic pathways in an organism
• C. To study the ecological interactions of an organism
• D. To identify the proteins expressed by an organism

Answer: (A)

Verified step by step guidance

1. Understand that a genome-sequencing project focuses on determining the complete DNA sequence of an organism's genome. This involves identifying the order of nucleotides (adenine, thymine, cytosine, and guanine) in the DNA.
2. Recognize that the primary goal of genome sequencing is not directly related to analyzing metabolic pathways, which involves studying the chemical reactions within a cell.
3. Acknowledge that studying ecological interactions involves understanding how an organism interacts with its environment and other organisms, which is not the main focus of genome sequencing.
4. Realize that identifying proteins expressed by an organism is part of proteomics, which involves studying the proteins encoded by the genome, but it is not the primary goal of genome sequencing itself.
5. Conclude that the primary goal of a genome-sequencing project is to determine the complete DNA sequence of an organism's genome, providing a comprehensive map of its genetic material.
