Some mutations can affect the structure of one or more chromosomes - these are chromosome structure mutations.

To prepare the 46 chromosomes of a human cell for transport to the daughter cells during cell division, each chromosome forms a compact X-shaped structure with two rod-like copies. How the cell ...

Chances are you've seen an illustration of DNA's double-helix structure and even pictures of the chromosomes that make up the human genome. But where and how does the famous double helix fit into ...

The diagram shows the chromosomes of three different people. Individuals A and B both have brown eyes, even though A is heterozygous and B is homozygous (dominant). Only people with a homozygous ...

These motors play distinct roles in manipulating chromosome structure. Swimming motors, similar to RNA polymerases—enzymes that copy DNA sequences into RNA—help expand and contract the ...
