This stunning Maya animation covers the death receptor signaling pathway that originates with binding of the Fas/TNF family of ligands, triggering of the caspase cascade, cytochrome C release from the mitochondria, apoptosome activation, and ensuing signal amplification.
Still one of the more complex and beautiful molecular animations ever made, this movie shows the components and dynamic processes involved in the replication of both the leading and lagging strands of DNA.
Introduction to Transcription - part I | Drew Berry
Transcription factors assemble at a DNA promoter region found at the start of a gene. Promoter regions are characterised by the DNA's base sequence, which contains the repetition TATATA É and for this reason is known as the "TATA box".
Introduction to Transcription - part II | Drew Berry
The RNA polymerase unzips a small portion of the DNA helix exposing the bases on each strand. One of the strands acts as a template for the synthesis of an RNA molecule. The base-sequence code is transcribed by matching these DNA bases with RNA subunits, forming a long RNA polymer chain.
A visualization of a cell's cytosplasm derived from electron tomography data from Brad Marsh's laboratory. The different components - nucleus, microtubules, mitochondria, ribosomes, smooth ER, rough ER, Golgi - are highlighted in separate 'passes' and then overaid as one. A great reminder of how crowded cellular interiors are!
Part 3 in Drew Berry's "Central Dogma" animations - the mRNA (yellow) is decoded inside the ribosome (purple and light blue) and translated into a chain of amino acids (red) as aminoacyl-tRNAs (green) deliver each amino-acid cargo (red/pink tip) to the ribosome.
This animation represents part-1 of a 2-part series depicting the events of the malaria parasite lifecycle.
The parasite is shown entering the human host following a mosquito bite and we follow its progression initially to the liver and subsequently targeting erythrocytes on a large scale.
This animation depicts the proces of DNA recombination. The DNA plasmid is first digested with the restriction endonuclease enzyme ecoRI. Then, a piece of DNA encoding a gene is inserted into the plasmid by DNA ligase.
This animation depicts hemoglobin molecules binding to oxygen. The mutant form of hemoglobin is also shown and results in the assembly of the long stiff protein fibers characteristic of the disease sickle cell anemia.
