Deoxyribonucleic acid, or DNA, is the genetic material responsible for passing traits from generation to generation in all organisms and most…
![The Central Dogma](https://jovecdn2.ccindex.cn/files/media/science-education/science-education-thumbs/10798.jpg)
The central dogma of biology states that information encoded in the DNA is transferred to messenger RNA (mRNA), which then directs the synthesis of…
![Eukaryotic Compartmentalization](https://jovecdn2.ccindex.cn/files/media/science-education/science-education-thumbs/10689.jpg)
One of the distinguishing features of eukaryotic cells is that they contain membrane-bound organelles, such as the nucleus and mitochondria, that…
![The Tree of Life - Bacteria, Archaea, Eukaryotes](https://jovecdn2.ccindex.cn/files/media/science-education/science-education-thumbs/11482.jpg)
The “tree of life” describes the evolution of life and the evolutionary relationships between organisms. The root of the tree is the…
![Gene Evolution - Fast or Slow?](https://jovecdn2.ccindex.cn/files/media/science-education/science-education-thumbs/11484.jpg)
The genomes of eukaryotes are punctuated by long stretches of sequence which do not code for proteins or RNAs. Although some of these regions do…
![Genome Size and the Evolution of New Genes](https://jovecdn2.ccindex.cn/files/media/science-education/science-education-thumbs/11485.jpg)
While every living organism has a genome of some kind (be it RNA, or DNA), there is considerable variation in the sizes of these blueprints. One…
![Combined Genetic and Chemical Capsid Modifications of Adenovirus-Based Gene Transfer Vectors for Shielding and Targeting](https://jovecdn2.ccindex.cn/files/thumbs/58480_t.png)
Adenovirus vectors are potent tools for genetic vaccination and oncolytic virotherapy. However, they are prone to multiple undesired vector-host…
