Study reveals how the ovarian reserve is established

Fertility is finite for mammalian females. From birth, females possess a limited number of primordial follicles, collectively called the ovarian reserve. Within each follicle is an oocyte that eventually becomes an egg. But ...

Investigators explore cellular response to stress

Northwestern Medicine investigators have discovered novel mechanisms that regulate a cell's response to molecular stressors, according to a study published in the Proceedings of the National Academy of Sciences.

How do plants adapt to aquatic environments?

The theory that life began in the ocean is widely accepted. The public, however, does not acknowledge the reality that many aquatic organisms are descendants of terrestrial organisms. Whales and dolphins are marine mammals ...

Exploring molecular boundaries in DNA

It's important to be well organized. And this is especially true for the genome—the entirety of an organism's genetic information, also known as DNA. The genomic DNA is several meters long but has to fit inside the cell's ...

Molecular genetics

Molecular genetics is the field of biology that studies the structure and function of genes at a molecular level. The field studies how the genes are transferred from generation to generation. Molecular genetics employs the methods of genetics and molecular biology. It is so-called to differentiate it from other sub fields of genetics such as ecological genetics and population genetics. An important area within molecular genetics is the use of molecular information to determine the patterns of descent, and therefore the correct scientific classification of organisms: this is called molecular systematics.

Along with determining the pattern of descendants, molecular genetics helps in understanding genetic mutations that can cause certain types of diseases. Through utilizing the methods of genetics and molecular biology, molecular genetics discovers the reasons why traits are carried on and how and why some may mutate.
