is a thin-leaved deciduous hardwood tree of the genus Betula (/ˈbɛtjʊlə/), in the family Betulaceae, which also includes alders, hazels, and hornbeams.
The central dogma of molecular biology is an explanation of the flow of genetic information within a biological system. It is often stated as "DNA makes RNA, and RNA makes protein",although this is not its original meaning

Over 200 million year old, one of the oldest living tree species
monoecious, bearing both male and female flowers on the same plant. The small flowers are unisexual, the female flowers borne in pairs, the male flowers wind-pollinating catkins. They are produced in spring shortly after the new leaves appear. The fruit of the beech tree, known as beechnuts or mast, is found in small burrs that drop from the tree in autumn. They are small, roughly triangular and edible, with a bitter, astringent, or mild and nut-like taste.
With a few exceptions, alders are deciduous, and the leaves are alternate, simple, and serrated. The flowers are catkins with elongate male catkins on the same plant as shorter female catkins, often before leaves appear; they are mainly wind-pollinated, but also visited by bees to a small extent. These trees differ from the birches (Betula, another genus in the family) in that the female catkins are woody and do not disintegrate at maturity, opening to release the seeds in a similar manner to many conifer cones.
The largest species are red alder (A. rubra) on the west coast of North America, and black alder (A. glutinosa), native to most of Europe and widely introduced elsewhere, both reaching over 30 metres (100 ft). By contrast, the widespread Alnus alnobetula (green alder) is rarely more than a 5 m-tall (16 ft) shrub.
