Chemical kinetics focuses on the speed, or rate, at which chemical reactions occur. Unlike thermodynamics, which explains whether a reaction can happen, chemical kinetics examines how fast it happens. By studying chemical kinetics, you can identify the factors that influence reaction rates and learn how to control these rates for applications in industries, biology, and …

Bacteriophage Life Cycles: Understanding Lytic and Lysogenic Phases
Bacteriophages, or phages, are viruses that specifically infect bacteria. Unlike other viruses, they are specialized to recognize and enter bacterial cells. Once inside, they use the bacteria’s machinery to replicate. Bacteriophages have two life cycles: the lytic cycle, where they reproduce and cause the bacteria to burst, and the lysogenic cycle, where they integrate their …
