DNA structure and function.
The proposal of a double-helical structure for DNA over 60 years ago provided an eminently satisfying explanation for the heritability of genetic information. But why is DNA, and not RNA, now the dominant biological information store? We argue that, in addition to its coding function, the ability of DNA, unlike RNA, to adopt a B-DNA structure confers advantages both for information accessibilit...

متن کاملStructure and Function of Dna
For a number of years a new scientiJc unity has been developing frotn a synthesis itz which chemistry and physics have become closely lirlked with biology. On the biological side cytologists are concerned with what happens to the nucleo-proteins and the nucleic acids present in plant and animal cells. These compounds are of great interest to biochemists atld biophysicists, and during I953 impor...
متن کاملcompactifications and function spaces on weighted semigruops
chapter one is devoted to a moderate discussion on preliminaries, according to our requirements. chapter two which is based on our work in (24) is devoted introducting weighted semigroups (s, w), and studying some famous function spaces on them, especially the relations between go (s, w) and other function speces are invesigated. in fact this chapter is a complement to (32). one of the main fea...
15 صفحه اولDNA topoisomerases: structure, function, and mechanism.
DNA topoisomerases solve the topological problems associated with DNA replication, transcription, recombination, and chromatin remodeling by introducing temporary single- or double-strand breaks in the DNA. In addition, these enzymes fine-tune the steady-state level of DNA supercoiling both to facilitate protein interactions with the DNA and to prevent excessive supercoiling that is deleterious...
