A chromosome is a package for DNA.
Mark Skolnick discusses how luck was a major element that helped his team win the race to find and clone BRCA1.
DNA is organized into 46 chromosomes including sex chromosomes, 3D animation
Each chromosome consists of one continuous thread-like molecule of DNA coiled tightly around proteins, and contains a portion of the 6,400,000,000 basepairs (DNA building blocks) that make up your DNA.
Each chromosome is a package for one very long, continuous strand of DNA.
Repetitive DNA can have preferred insertion sites. In this example, yellow represents the distribution of mys (a type of LINE) over a mouse genome where chromosomes are orange. There are more mys inserted in the sex (X) chromosomes.
