In certain cases, genetic testing can identify mutant alleles that greatly increase a person's chance of developing a disease such as breast cancer or colon cancer. Between 50 and 70% of people with these particular mutations will develop cancer, but the rest will not. Imagine you are either a 30-year-old woman with a family history of breast cancer or a 30-year-old man with a family history of colon cancer (choose one). Each person can undergo genetic testing to identify a mutation that greatly increases susceptibility to the disease. Putting yourself in the place of the person you have chosen, provide answers to the following questions.
If this person that you have selected were you, do you think you would have the genetic test or not? Can you explain the reasons for your answer?

Understand the term 'Proteomics': Proteomics is a branch of molecular biology that focuses on the large-scale study of proteins, particularly their structures and functions.
Recognize the role of proteins: Proteins are essential molecules that perform a vast array of functions within organisms, including catalyzing metabolic reactions, DNA replication, responding to stimuli, and transporting molecules.
Differentiate from other 'omics' fields: Unlike genomics (study of DNA) or transcriptomics (study of RNA transcripts), proteomics specifically deals with the entire set of proteins produced or modified by an organism or system.
Consider the methods used in proteomics: Techniques such as mass spectrometry and protein microarrays are commonly used to analyze the protein content of a sample.
Apply this understanding to the question: Given the options DNA, RNA, Transcripts, and Proteins, the study of proteomics is most directly related to Proteins.
