How does Spectral Karyotyping work if there are millions of DNA sequences....?
| |
Sarah Anzick, Ph.D.: Spectral Karyotyping is a technique in which each of the chromosomes are sorted into separate tubes and then are fluorescently labeled with a different color. Sequences that are shared between the chromosomes are blocked so the chromosome specific sequences stay labeled with the chromosome specific color. |
