Franklin interpreted them as representing distances between the nucleotides that were arranged in a spiral shape called a helix ... DNA is then arranged into structures called chromosomes.

In cells, the DNA helix is often overwound ... times to condense the DNA into a smaller volume. Additionally, DNA chromosomes are often recognized and depicted as X-shaped structures.

The backbone of the DNA double helix consists of alternating phosphate and deoxyribose sugar molecules. Interlinking bases hold the two sides together. As A is complementary to T and C is ...

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 ...

Illustration of a gene within a DNA sequence, showing the organization from chromosome to DNA double helix. The image highlights the start and stop codons that mark the beginning and end of the gene, ...

So, it's very easy to see,” she said. To zoom in on changes in chromosome organization during meiosis, the researchers used nuclear membrane and DNA damage protein stains to track nuclear behavior.

This organization can be explained by weak interactions between nucleosomes, which are the repetitive blocks that fold the ...

DNA comprises the genes and chromosomes that govern the development ... The twisted double strand structure -- the famed double helix -- unwinds and the strands separate. The nucleotides (A ...
