Everything about Double Helix totally explained
» For other meanings of double helix, see Double helix (disambiguation)
In
geometry a
double helix (plural
helices) typically consists of two
congruent helices with the same axis, differing by a
translation along the axis, which may or may not be half-way.
In
Molecular Biology, the double helix refers to the structure of
DNA. The structure of
DNA was first published in the journal
Nature by
James D. Watson and
Francis Crick in 1953, based upon data from
Maurice Wilkins and
Rosalind Franklin. Crick, Wilkins and Watson each received the
Nobel Prize for their contributions to the discovery. Franklin died before her contribution could be acknowledged, and due to the fact that they can't be awarded posthumously, never received a Nobel Prize.
The DNA double helix is a right-handed spiral polymer of
nucleic acids, held together by
nucleotides which
base pair together. A single turn of the helix constitutes ten nucleotides.
The order, or
sequence, of the nucleotides in the double helix within a
gene specifies the
primary structure of a
protein .
