DNA helices
DNA helices. Models showing the double helix and nucleotide base structure of DNA (deoxyribonucleic acid) molecules. The double helix is formed by two spiralling strands of sugar phosphates. Nucleotide bases (red, blue, yellow, green) are arrayed along these strands. The four bases can form two bonding pairs: adenine bonds to thymine and cytosine bonds to guanine. This complementary base pairing holds the two strands together to form the DNA ladder. DNA is found in cell nuclei, and the sequence of its nucleotide bases forms the genetic code for protein synthesis and the functioning and growth of every living organism

EDITORS COMMENTS
This print from Science Photo Library showcases the intricate structure of DNA helices, providing a visual representation of the fundamental building blocks of life. The models depicted here beautifully illustrate the double helix formation, consisting of two spiralling strands composed of sugar phosphates. Along these strands, nucleotide bases in vibrant red, blue, yellow, and green are arranged meticulously. The significance of this arrangement lies in the complementary base pairing that occurs between these four bases. Adenine bonds with thymine while cytosine pairs with guanine to create a stable structure known as the DNA ladder. This remarkable bonding pattern is responsible for holding the two strands together and forming the iconic double helix shape. DNA is an essential component found within cell nuclei and serves as a blueprint for protein synthesis and growth in all living organisms. Its sequence of nucleotide bases forms the genetic code that determines our hereditary traits and influences various biological processes. Through this visually striking image, we gain insight into molecular biology's complexity while appreciating its elegance. It reminds us how genetics play an integral role in shaping life itself – a testament to nature's awe-inspiring intricacy captured by Science Photo Library's remarkable photography skills.
