DNA's iconic double helix does more than "just" store genetic information. Under certain conditions, it can temporarily fold into unusual shapes. Researchers at Umeå University, Sweden, have now shown ...
The DNA packed inside every human cell contains instructions for life, written in billions of letters of genetic code. Every time a cell divides, the complete code, divided among 46 chromosomes, must ...
Like its viral cousins, a somewhat parasitic DNA sequence called a retrotransposon has been found borrowing the cell's own machinery to achieve its goals. In a new work appearing online Wednesday in ...
Under physiological conditions, most double-stranded nucleic acids adopt right-handed helical conformations such as B-DNA or A-RNA. However, under specific cellular stresses, nucleic acids can ...
