parthenogenesis

Parthenogenesis is an asexual form of reproduction found in females where growth and development of embryos or seeds occurs without fertilization by males. The offspring produced by parthenogenesis almost always are female in species where the XY chromosome system determines gender.

Parthenogenesis occurs naturally in some species, including most lower plants, a Kalanchoe succulent plant genus of South Africa, invertebrates (e.g. water fleas, aphids, some bees, some scorpion species, and parasitic wasps), and vertebrates (e.g. some reptiles, fish, and, very rarely, birds and sharks) and this type of reproduction has been induced artificially in other species.

The term is sometimes used inaccurately to describe reproduction modes in hermaphroditic species which can reproduce by themselves because they contain reproductive organs of both genders.

Description and Significance

Thiomargarita namibiensis ("Sulfur pearl of Namibia") is a gram-negative coccus Proteobacterium found in the ocean sediments of the continental shelf. It has the distinction of being the largest bacterium ever discovered, with a width up to 750 μm (0.75 mm), making it easily visible to the naked eye.

A DNA composite transposon.

Transposons are sequences of DNA that can move around to different positions within the genome of a single cell, a process called transposition. In the process, they can cause mutations and change the amount of DNA in the genome. Transposons are also called "jumping genes", and are examples of mobile genetic elements. Discovered by Barbara McClintock early in her career, the discovery earned her a Nobel Prize in 1983. There are a variety of mobile genetic elements, and they can be grouped based on their mechanism of transposition. Class I mobile genetic elements, or retrotransposons, move in the genome by being transcribed to RNA and then back to DNA by reverse transcriptase, while class II mobile genetic elements move directly from one position to another within the genome using a transposase to "cut and paste" them within the genome. Transposons are very useful to researchers as a means to alter DNA inside of a living organism. Transposons make up a large fraction of genome sizes which is evident through the C-values of eukaryotic species.
