Concept explainers

Genomic studies

Genomic studies (genomics) is the study of the whole genome of an organism. Using bioinformatics and high-performance computing, genomic researchers examined massive amounts of deoxyribonucleic acid (DNA)-sequence data to discover variations or mutations that affect drug response, health, or disease. Genomics is a much younger discipline than genetics, having only emerged in the last few decades as a result of technological advancements in DNA sequencing and computational biology.

If cancer is fundamentally a genetic disease, how might an
environmental factor such as smoking cause cancer?

Expert Solution

Step 1

Tumor is a mass of tissues. It may be benign or malignant. The cellular growth that occurs when the cells divide uncontrollably is known as cancer. It arises as a result of fundamental defects in the regulation of cell division.

Unlike many other diseases, the vast majority of cancers in humans are not transmissible - meaning a person can’t ‘catch cancer’ from someone else. How does a person get cancer, then? Starting with a normal (non-cancerous) cell, describe a possible sequence of events that could eventually result in metastasized cancer, including the genes, structures or processes involved.
What are the biggest challenges that mutations pose to oncologists and cancer biologists who seek to find novel cures against cancers?
Cancer can arise spontaneously, but it can also be induced as a result of environmental factors such as sun exposure, infections, and tobacco smoking. If you were asked to help allocate resources to cancer research, what emphasis would you place on research to find cancer cures, compared to that placed on education about cancer prevention?
