DNA was discovered in 1869 ... The next step was to find out its structure, in order to understand how the gene, the basic unit of heredity, works and how it is passed from one generation to ...

Chances are you've seen an illustration of DNA's double-helix structure and even pictures of the chromosomes that comprise the human genome. But where and how does the famous double helix fit into ...

Later, in 1960, the discovery that an RNA molecule and a DNA molecule could ... But as far as their structure is concerned, these RNAs all share the same basic single-stranded chemical structure ...

Cells use many complex genetic repair backup systems to fix DNA damage and remain healthy throughout their lives.

To design a DNA structure, scientists start with a desired shape or pattern and then determine the complementary DNA sequences that will allow the DNA strands to self-assemble into that structure.

Attempts to do so have relied on chemicals that damage the DNA structure or strategies that ... "It holds important implications for our basic understanding of biology, but also for the ...

By studying this amazing structure ... matrix (in the same way that basic proteins known as histones help compact and organize nuclear DNA). To prove this idea, researchers designed a very ...

Proteins are fundamental biomolecules that perform a broad range of vital functions within the human body. They serve as an essential structural and functional component of cells, tissues and organs ...
