Molecular mapping is a research area that involves the identification and mapping of specific genes or DNA sequences within an organism's genome. This process can help researchers better understand the genetic basis of various traits or diseases, as well as aid in the breeding of plants or animals for desired traits. Molecular mapping often involves techniques such as polymerase chain reaction (PCR), DNA sequencing, and genetic markers to locate and analyze specific genes or regions of interest within the genome. By studying the molecular maps of different organisms, researchers can gain insights into the genetic mechanisms underlying various biological processes and characteristics.
