The 2009 Nobel Prize in Chemistry was awarded jointly to Venkatraman Ramakrishnan, Thomas Steitz and Ada Yonath “for studies
on the structure and function of the ribosome”. The ribosome is a massive molecular machine comprising proteins and RNA and
is responsible for the synthesis of proteins, often termed the workhorses of the cell. Proteins are key players in almost
all intracellular transactions and hence the importance of the ribosome. 相似文献

The Handicap Principle is an idea proposed by the husband and wife scientist team of Amotz and Avishag Zahavi from Israel
in the 1970’s. It is among the most innovative ideas of the 20th century in the field of behavioural biology and attempts
to explain several long-standing puzzles that have baffled naturalists since the time of Darwin. Although the theory was initially
met with scepticism by the scientific community, with time and with sophisticated mathematical modelling it has now gained
wider acceptance. In the book explaining their idea, the authors discuss various observations of animal behaviour in the wild
and suggest how these can be explained using the handicap principle. Both experiments and long-time observations of animal
behaviour fit in smoothly with the authors’ hypotheses for the most part. In this article I discuss the concept of the handicap
principle and its application to various biological phenomena. 相似文献
