Just when I was about to blog on this paper in cell by Asako Sakaue-Sawano, Hiroshi Kurokawa et al. I found that it was already beautifully blogged by “pure pendantry“. It is another example of imaging live cells with tagged proteins. I found the picture titled “A Survey of the Cell Cycle [...]

We have a nice comparison article at pharyngula on animal and plant development and how we are related.
The first blog I read today and inspired me to get to work early :).

Last week I blogged on the talk by Peter Fraser where he showed evidence for the existence of transcription factories. He showed pictures as follows to demonstrate the theory of transcription factory.
Fig. 1. Transcription factories are concentrated foci of active RNA polymerase. Immuno-detection of the hyper-phosphorylated form of RNAPII reveals their [...]

I read this nice article by Mark Pagel on the genetics of Human race. A very appropriate article for today’s world where the word “RACE” is perceived as a social construct used to discriminate groups.

Today we had a very fascinating story by Peter Fraser (from the Babraham Institute, Cambridge), suggesting that genes migrate to specialized sites called transcription factories in the nucleus for transcription. These transcription factories are nothing but discrete foci in the nucleus containing high concentrations of RNA polII(the eukaryotic polymerase responsible for transcription of protein-coding [...]
