20世纪中叶,随着蛋白质空间结构的X射线解析和DNA双螺旋的发现,科学开始了一个分子生物学时代:与过去单向单学科的科学实验不同,跨界跨学科跨地区的协同作业,成为了新学科研究与实验的主要方式。于是,一批交叉学科应运而生(生物化学、生物物理学、生物工程学、生物信息学等)。而这些与生命相关的学科的迅速发展,最终导致了人类基因组计划的完成。21世纪是属于生物学的世纪。 In the middle of the 20th century, with the analysis of the X-ray structure of DNA and the discovery of DNA double helix, science started a molecular biology era. Different from the scientific experiments in the past one-way and one-discipline, cross-disciplinary and trans-regional collaborative work, Became the new discipline research and experiment the main way. As a result, a number of interdisciplinary projects emerged (biochemistry, biophysics, bioengineering, bioinformatics, etc.). The rapid development of these life-related disciplines eventually led to the completion of the Human Genome Project. The 21st century is a century of biology.
