Biology DEBATE Advances in biotechnology are side by side with the growth of bio-based industries, companies in the industrial sector aiming to exploit the techniques involving living organisms used for food, pharmaceutical, medical, and others. The pharmaceutical industry, for example, aimed at the production of animals known as bioreactors. These animals are already domesticated by humans, and which can be used for the production of human recombinant proteins of high biological and commercial interest, such as enzymes, hormones, vitamins, growth factors and other biological. Thus, if used, completed and cows or goats, the protein of interest was synthesized by these animals and expressed in milk, making production cheaper and more efficient. One of these proteins would be lactalbumin. Now is with you and your colleagues: research about this content and discuss the pros and cons of this practice. Also search, it is possible to produce plants with bioreactors. That the phenomena of nature have always been objects of interest to humans, we can not deny. Explanations for natural phenomena, such as the diversity of species and the origin of this diversity, have been proposed as models for scientific naturalists and thinkers since the Greek Antiquity. Charles Darwin (1809 - 1882) and other naturalists contributed explanations for these phenomena. The explanatory model of natural selection, summarized by him in the nineteenth century, proposes that individuals best adapted to the environment are "selected" to have more chances to survive thanks to the charac- tics and which have thus leaving un- Species diversity.

During years of research, contributions and incorporation of new ideas that have joined the explanations of natural selection to explain how the characteristics of individuals or population remained in subsequent generations. Two topics were revealed in surveys: the inheritance, for discussions aimed at causes of similarities between individuals, and variation, for discussions aimed at causes of differences between individuals. To explain them, take the view are two extremely important factors: mutation and recombination occurred in the genes. Mutation refers to the changes that may occur in the DNA sequence, either in one or in several genes, leading to other genetic sequences that can produce new offspring characteristics in individuals. It is noteworthy that the changes will not always favor- The food you consume daily is transgenic?

Biologija DEBATA Napredak u biotehnologiji su rame uz rame s rastom od bio-based industrije , tvrtke u industrijskom sektoru s ciljem iskorištavanja tehnike koje uključuju živih organizama koji se koriste za hranu, farmaceutske, medicinske, i drugi. Farmaceutska industrija, primjerice, usmjeren na proizvodnju životinja poznat kao bioreaktorima. Te životinje su već udomaći ljudi, a koji se može koristiti za proizvodnju ljudskih rekombinantnog proteina visoke biološke i komercijalnih interesa, poput enzima, hormona, vitamina, čimbenika rasta i drugih bioloških. Dakle, koristi- up dovršen i krave ili koze, proteina od interesa priređen je ovih životinja i izražava u mlijeku, što proizvodnja jeftinije i učinkovitije. Jedan od tih proteina bi laktalbumin. Sada je s vama i vašim kolegama: Istraživanje o ovom sadržaju i raspravljati o pro i kontra od ove prakse. Također traži, moguće je proizvesti biljke s bioreaktorima. To su fenomena prirode oduvijek su bili predmet interesa za ljude, ne možemo poreći. Objašnjenja za prirodnim pojavama, kao što su raznolikosti vrsta i podrijetlo ove raznolikosti, predložene su kao modeli za znanstvene prirodnjaka i mislilaca, od grčke antike. Charles Darwin (1809 - 1882), a drugi prirodoslovci pridonio objašnjenja za ove fenomene. Objašnjiv model prirodne selekcije, sažeo ga je u devetnaestom stoljeću, predlaže da pojedinci najbolji adaptirani za okoliš su "odabrani" imati više šanse za preživjeti zahvaljujući lika- tikovi i koji na taj način imaju ostavljajući UN- raznolikosti vrsta.

Tijekom godina istraživanja, doprinose i ugradnja novih ideja koje su se pridružile objašnjenja prirodne selekcije objasniti kako su karakteristike pojedinaca ili su ostali u narednim generacijama. Dvije teme su otkrili u anketama: nasljedstvo , za razgovore usmjerene na uzroke sličnosti između pojedinaca, i promjena , razgovori su se okrenuli uzroka razlika između pojedinaca. Da im objasni, kon- ovna do dva iznimno važna čimbenika: mutacije rekombinacije dogodila u genima. Mutacija se odnosi na promjene koje se mogu pojaviti u slijedu DNA, bilo u jednom ili u nekoliko gena, što dovodi do drugih genetskih sekvenci koje mogu proizvesti nove potomke osobine pojedinaca. Važno je napomenuti da su promjene koje nisu uvijek će pogodovati- Hrana koju konzumiraju svakodnevno je transgenetska?
