Question

請問
生物化學
和
分子生物學
有何不同？

謝謝。

Answer 1

生物化學是研究一切跟生命有關的化學
例如各種醣類、蛋白質、脂質、核酸以及它們經由各種路徑所製造出來的其他代謝產物(當然這些路徑也是生化研究的一部分)，還有細胞構造的化學層級阿等等很多很多的

分子生物學應該算是包含在生物化學的一小部份
再更深入研究細胞中與核酸(DNA和RNA應該知道吧)有關的各種問題，例如核甘酸定序、DNA複製、RNA轉錄、轉譯及它們的調控等等

大致上就是這樣吧，所學有限希望幫得上忙

Researchers in biochemistry use specific techniques native to biochemistry, but increasingly combine these with techniques and ideas from genetics, molecular biology and biophysics. There has never been a hard-line between these disciplines in terms of content and technique, but members of each discipline have in the past been very territorial; today the terms molecular biology and biochemistry are nearly interchangeable. The following figure is a schematic that depicts one possible view of the relationship between the fields:Biochemistry is the study of the chemical substances and vital processes occurring in living organisms. Genetics is the study of the effect of genetic differences on organisms. Often this can be inferred by the absence of a normal component (e.g. one gene). The study of "mutants" – organisms which lack one or more functional components with respect to the so-called "wild type" or normal phenotype. Genetic interactions (epistasis) can often confound simple interpretations of such "knock-out" studies. Molecular biology is the study of molecular underpinnings of the process of replication, transcription and translation of the genetic material. The central dogma of molecular biology where genetic material is transcribed into RNA and then translated into protein, despite being an oversimplified picture of molecular biology, still provides a good starting point for understanding the field. This picture, however, is undergoing revision in light of emerging novel roles for RNA. Chemical Biology seeks to develop new tools based on small molecules that allow minimal perturbation of biological systems while providing detailed information about their function. Further, chemical biology employs biological systems to create non-natural hybrids between biomolecules and synthetic devices (for example emptied viral capsids that can deliver gene therapy or drug molecules).

基本上分子生物學是包含在生物化學裡面的
所以學了生物化學基本上會學到基礎的分子生物學
而近幾年分子生物學日益的發展
所以要深入研究分子生物學是已經超出了生物化學的範疇裡面了
