Beyond the ladder-like structure described above, another key characteristic of double-stranded DNA is its unique three-dimensional shape. The first photographic evidence of this shape was ...

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 ...

But James Watson and Francis Crick's claim was a valid one, for they had in fact discovered the structure of DNA, the chemical that encodes instructions for building and replicating almost all ...

This way DNA can reproduce itself without changing its structure -- except for occasional errors, or mutations. The structure so perfectly fit the experimental data that it was almost immediately ...

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.

The basic pattern of genomic DNA methylation ... might maintain their unique heterochromatin structure through DNA sequences that recruit the machinery necessary for methylating H3K27, a mark ...

The basic structure of most animal and plants cells is shown below. All cells are produced from other cells by the process of cell division. Cell division occurs when one cell divides to produce ...

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 ...

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 ...
