At different times during the life cycle of a cell, the DNA that makes up the cell's chromosomes can be tightly compacted into a structure that is visible under a microscope, or it can be more ...

Each of us has enough DNA to reach from here to the sun and back, more than 300 times. How is all of that DNA packaged so tightly into chromosomes ... quite the uniform structure depicted in ...

Specialized protein machines called SMC complexes (Structural Maintenance of Chromosomes) play a critical role in these ...

Scientists worked out the structure of DNA in the 1950s ... blood group and height. Our largest chromosome contains about 8000 genes. Humans have between 20 000 and 25 000 genes.

The dark bands indicate areas where the structure of the chromosome is dense ... A single gene can range in length from as few as 100 DNA bases to as many as several million.

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, respectively. The different colored bases ...

Scientists from the Kavli Institute of Delft University of Technology and the IMP Vienna Biocenter discovered a new property ...

New research shows that SMC proteins loop and twist DNA consistently in both humans and yeast, impacting DNA structure and ...

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 ...

A 2017 study published in the journal PLOS Genetics said the chromosome's evolution of palindromes — DNA sequences that read the same forward as backward — and repetitive copies of genes could ...
