DNA is organized into 46 chromosomes including sex chromosomes, 3D animation
Transcript:
The millions of bases, which make up the human genome are organized into structures called chromosomes. These are arranged into 22 matching pairs plus 1 pair of sex chromosomes consisting of 2 X's in women and an X and a Y in men. So humans have a total of 46 chromosomes in each cell, known collectively as a karyotype. This set of chromosomes has a Y, so it must belong to a male.

Professor David Porteous explains that breakpoints in the genome are locations on a chromosome where DNA might get deleted, inverted, or swapped around.
James Watson describes sequencing the human genome using markers and BACs, and Craig Venter explains using cDNA libraries, ESTs, and shotgun sequencing.
A portrait of human chromosomes: this process labels the chromosomes with multicolored
fluorescent tags, allowing researchers to consistently distinguish between chromosomes.
