This week prefromed an expanion microscopy experiment to scale up a mouse brain. This was truely amazing.
Expansion Microscopy (ExM): a sample preparation tool for biological samples that allows investigators to identify small structures by expanding them using a polymer system. This TED talk by Ed Boyden explains the inspiration, technique and use.
Central dogma of molecular biology: the two-step process, transcription and translation, by which the information in genes flows into proteins: DNA → RNA → protein. Transcription is the synthesis of an RNA copy of a segment of DNA. RNA is synthesized by the enzyme RNA polymerase.
Histone code: a hypothesis that the transcription of genetic information encoded in DNA is in part regulated by chemical modifications to histone proteins, primarily on their unstructured ends. Together with similar modifications such as DNA methylation it is part of the epigenetic code.
