High-cell-density cultivation (HCDC)

High-cell-density cultivation (HCDC) is a process that improves the formation of microbial biomass and products. It can be used for microorganisms such as bacteria, archaea, and yeasts. HCDC can make the fermentation process […]

How to protect RNA from degradation?

To protect RNA from degradation, you can:  RNA is prone to enzymatic degradation and hydrolysis. Even at low temperatures, RNA can still be reactive, and some ribozymes can be enhanced by […]

What is the main reason for RNA being unstable?

Unlike DNA, RNA is usually single-stranded. Additionally, RNA contains ribose sugars rather than deoxyribose sugars, which makes RNA more unstable and more prone to degradation. RNA is generally stable at –80° […]

Potential Reasons for Lack of Supercoiled DNA

Conclusion In conclusion, the absence of apparent supercoiling in plasmid DNA preparations can result from a variety of factors related to DNA extraction, purification, handling, and analysis. By systematically addressing […]

The Principle of Transformation

As DNA is a highly hydrophilic molecule, it usually cannot pass through the cell membrane of bacteria. Hence, to make bacteria capable of internalizing genetic material, they must be made […]
