Overview and Comparison of Protein Expression Systems

Protein production systems are largely used in biotechnology and in our class Biotechnology 51 (Introduction to Biomanufacturing) we studied and compared the different types of protein expression systems. 1,015 more words

Eukaryotes: A new timetable of evolution

The first single-celled organisms with a nucleus originated more than a billion years later than biogeochemical evidence had previously indicated.

Contaminated samples have evidently created some confusion in the timetable of life. 1,333 more words

May 06, 2015

In a new study, published in Nature this week, a research team led from Uppsala University in Sweden presents the discovery of a new microbe that represents a missing link in the evolution of complex life. 727 more words


The Origins of Eukaryotes: Metagenomic insight into early evolution

The origins of the eukaryotic cell is one of the big puzzles of cell biology. While it has been known for a long time that the eukaryotes are more closely related to the Archaea than to the Bacteria, the ancestor of the eukaryotes has remained elusive. 365 more words


Lokiarchaeota: Missing link for complex cells?

History has given us many puzzles to solve in the field of evolution. According to a recent study, scientists at the Department of Cell and Molecular Biology, Science for Life Laboratory, Uppsala University, Sweden, identified a new class of Archaea, a microorganism that is made up of simple cells like bacteria, called “Lokiarchaeota”, which was noted as a possible missing link between bacteria and their more complex cousins, eukaryotes. 543 more words


The Cell

Cells are the smallest unit of life that can replicate independently, and are often called the “building blocks of life”. The study of cells is called cell biology. 871 more words


Between Darwin and Saint Valentine: Sex and Evolution

Imagine sex worked like this:

You’ve been feeling bad lately, getting sick a lot. You’re not at your best. You find someone who seems to be in better shape. 498 more words
