Because proteins are strings of amino acid s, it was proposed that a specific nucleotide sequence of DNA could contain a code for an amino acid sequence and hence protein structure.

Bioinformatics is the computer-based discipline that deals with the analysis of such large sets of biological information, especially as it applies to genomic information. The Terminologia Anatomica, produced by the International Federation of Associations of Anatomists and the Federative Committee on Anatomical Terminology later known as the Federative International Programme on Anatomical Terminologieswas made available online in After Galen, the next major figure in the history of anatomy is Andreas Vesalius — of Belgium.

Biology of flies and maggots Maggots are fly larvae, or immature flies, just as caterpillars are butterfly or moth larvae. These methods can be used on alleles of known phenotypic effect, such as the recessive allele for albinismor on DNA segments of any type of known or unknown function.

Trees constructed with other genes are generally similar, although they may place some early-branching groups very differently, presumably owing to rapid rRNA evolution.

With the invention of the electron microscopethe fine organization of the plastids could be used for further quantitative studies of the different parts of that process. According to legendShennong described the therapeutic powers of numerous medicinal plants and included descriptions of many important food plants, such as the soybean.

Mullis invented the polymerase chain reactiona method for rapidly detecting and amplifying a specific DNA sequence without cloning it. Although the Greek physician Hippocrateswho established a school of medicine on the Aegean island of Cos around bce, was not an investigator in the sense of Alcmaeon, he did recognize through observations of patients the complex interrelationships involved in the human body.

The mechanical philosophy—the belief that the universe and its constituent parts obeyed mechanical principles that could be understood and determined through reasoned observation and the new scientific method—thus made its way into the history of biology. A karyotype analysis usually involves blocking cells in mitosis and staining the condensed chromosomes with Giemsa dye.

He was one of the first to study major organ groups such as the brain, lungs, and kidneys in diverse organisms. Ebers papyrusEbers papyrus prescription for asthma treatment. Byon the basis of clinical and laboratory data like that described above, the U.

History of Biology: Cell Theory and Cell Structure

Medicine was especially well studied by Islamic scholars working in the Galenic and Aristotelian traditions, while natural history drew heavily on Aristotelian philosophy, especially in upholding a fixed hierarchy of life.

Transgenesis forms the basis of gene therapythe attempt to cure genetic disease by addition of normally functioning genes from exogenous sources. Mondino adhered closely to the works of the Greeks and Arabs, and he thus repeated their errors.

Gilbert and Sanger shared the Nobel Prize for Chemistry for their work. Muslim physician Avicenna was an outstanding scientist who lived during the late 10th and early 11th centuries; he was the true successor to Aristotle.

Foundations of modern biology Cell theory Human cancer cells with nuclei specifically the DNA stained blue.

The role of systematics is to study these relationships and thus the differences and similarities between species and groups of species. This view was widely publicized not by Remak but by Rudolf Virchow —unfortunately without crediting Remak.

History of biology

At Crotone in southern Italy, where an important school of natural philosophy was established by Pythagoras about bce, one of his students, Alcmaeoninvestigated animal structure and described the difference between arteries and veins, discovered the optic nerveand recognized the brain as the seat of the intellect.

The need for thinner, more transparent tissue specimens for study under the light microscope stimulated the development of improved methods of dissection, notably machines called microtomes that can slice specimens into extremely thin sections. Although he was opposed to evolution, Buffon is a key figure in the history of evolutionary thought ; his work influenced the evolutionary theories of both Lamarck and Darwin.

He is also a pioneer in attempting a system of classification. Biology is the natural science that studies life and living organisms, including their physical structure, chemical processes, Especially important are his History of Animals and other works where he showed naturalist leanings, and later more empirical works that focused on.

Biology - The Origins Of Biology

biology. If you’re studying the life cycles of living organisms, you’ve come to the right place. We break down the processes of everything from bacteria to blue whales. Anatomy: Anatomy, a field in the biological sciences concerned with the identification and description of the body structures of living things.

Biology Technology – Florida’s PreIB Biology 1 – IB Middle Years Program Biology – Integrated Science 3 – Biology: Biology, study of living things and their vital processes that deals with all the physicochemical aspects of life. Modern principles of other fields, such as chemistry, medicine, and physics, for example, are integrated with those of biology in areas such as biochemistry, biomedicine, and biophysics.

Genetics: Genetics, study of heredity in general and of genes in particular. Genetics forms one of the central pillars of biology and overlaps with many other areas, such as agriculture, medicine, and biotechnology.
