Every subject has its own category pages along with other subjects in the same category. Summarize the molecular mechanism involved in transcription and translation phenomena. Identify how DNA mutations influence protein structure and summarize how mutations may cause cancer.

Discover the unique family story that only your DNA can tell with a genetic test from Ancestry DNA, the world’s largest consumer DNA database. With a simple test, you’ll get meaningful insights into who you are and where you came from and find new relatives who share your DNA.

Molecular genetics is the field of biology that studies the structure and function of genes at a molecular level and thus employs methods of both molecular biology and genetics. The study of chromosomes and gene expression of an organism can give insight into heredity.

Gregor Mendel was the first to study genetics scientifically. Mendel's laws are the principles of transmission of hereditary traits from parents to their descendants. These principles served as the basis for classical genetics and were explained as a consequence of the molecular mechanisms of heredity.
