2.2 Chaperones help polypeptides to fold

We have seen how steric restrictions and energetic considerations specify preferred polypeptide conformations and ultimately determine a protein's three-dimensional structure. It is possible, of course, that there may be more than one energetically favourable conformation for a polypeptide. This is particularly true for large polypeptides. For a protein with a specific function in the cell, misfolding will affect its activity. Indeed, the misfolded protein may actually have some aberrant unde

1.8 Io

David A. Rothery Teach Yourself Planets, Chapter 9, pp. 107-39, Hodder Education, 2000, 2003.

Copyright © David Rothery

Of the welter of revelations provided by the Voyager tours of the outer Solar System, the discovery of active volcanoes on Io probably ranks top of the list. Prior to this, most people had assumed that bodies of Io's size, whether rocky like Io or icy like its companions, would be geologically dead like our own, similarly sized, Moon. This i

Spiders Alive! Q&A with Curator Norman Platnick
Do spiders have blood? Why don't they stick to their own webs? Is it better to be bitten by a black widow or a brown recluse? It's the last month of the Museum's Spiders Alive! exhibition, and the many different live spiders featured there have inspired some great questions from visitors. We asked the exhibit's spider handlers for the most interesting of the bunch and posed those questions to our in-house spider expert: Museum Curator Norman Platnick. In this video, Dr. Platnick provides some

4.2 Crinoids

Figure 7 shows the fossilised remains of a type of echinoderm called a crinoid ('cry-noyed'). Although crinoids occur today, they were far more common in the Palaeozoic and Mesozoic Eras. Most crinoids feed by bending their umbrella-like arrangement of flexible appendages (called 'arms') downstream so as to catch a current, rather as in an umbrella being caught in the wind. Tube feet (multipurpose tentacles) on the arms gather food particles suspended in the water, which are then wafte

Are you interested in investigating how nature engineers itself? How engineers copy the shapes found in nature ("biomimetics")? This Freshman Seminar investigates why similar shapes occur in so many natural things and how physics changes the shape of nature. Why are things in nature shaped the way they are? How do birds fly? Why do bird nests look the way they do? How do woodpeckers peck? Why can't trees grow taller than they are? Why is grass skinny and hollow? What is the wood science behind m

Managing virtual project teams
Many projects are now ‘virtual’, i.e. some or all of the team are located remotely and may be working in different time zones. The project manager needs all the traditional soft skills, and more. This free course, Managing virtual project teams, looks at knowledge and techniques which underpin team selection and then consider the additional expertise needed to manage teams in a virtual environment.Author(s): Creator not set
