Karen holds a 1st class Honours Bachelor Degree in Biological Sciences and a PhD in Biotechnology, both from Maynooth University in Ireland. She spent almost 10 years working as a researcher in both academic and industrial roles in Ireland and Denmark. Throughout her research career, Karen has worked with yeast, filamentous fungi, bacteria, plants, moth larvae and mammalian cells. She has tried her hand at everything from Sanger sequencing to genetically modifying disease-causing fungi. She loves science and is passionate about communicating science to others for educational purposes. Her passion for knowledge-sharing prompted her to join Bitesize Bio as a freelance writer (2014), a role which eventually progressed to Editorial Manager (until December 2017). In her (albeit limited) spare time, Karen loves to knit and enjoys life with her husband and son in Denmark. You can follow Karen on Twitter @KarenOHCohrt or at https://www.kcwritingforscience.com/

How to Manipulate Plasmid Copy Number

So far in this series, we have looked at origins of replication, we’ve discussed how plasmid replication is regulated in the popular pBR22 plasmid, and we’ve seen how a disturbance of this regulatory mechanism has given rise to the high-copy pUC18 plasmid. Are you ready for more plasmid talk?? If so, keep reading, as we…

qPCR: RNA Quality and Why It Matters

Gene expression analysis plays a pivotal role in a wide range of studies, including biomedical analysis and diagnostics. Of all the methods available for gene expression analysis, quantitative real-time PCR (qRT-PCR) is the most rapid, sensitive, and accurate to measure mRNA, and its use in clinical diagnostics is rising steadily. RNA quality entails both purity and…
