The molecular landscape refers to the complex network of interactions and relationships between various molecules within a cell or organism. This includes the genes, proteins, and other molecules that are present and how they interact with each other to regulate various cellular processes. Studying the molecular landscape allows researchers to understand how different molecules work together to maintain the function and health of a cell, as well as how changes in the molecular landscape can lead to diseases such as cancer. This area of research often involves techniques such as genomics, proteomics, and bioinformatics to analyze and interpret the data gathered from studying the molecular landscape.
