What is a chromosome?

A chromosome is an organized structure of DNA and protein found in cells. It is a single piece of coiled DNA containing many genes, regulatory elements and other nucleotide sequences. Chromosomes also contain DNA-bound proteins, which serve to package the DNA and control its functions.

Hello! To first Users

Hi! this is Junyoung Lee from the Hun School of Princeton
For first users! the 'DNA Finder' is a site for people who is curious about their ancestry.
Our Site focuses on informing anyone who is interested about this specific process and connecting them to websites where the process is actually taken.
Also, I have wrote some of my own experience so that people can understand in a similar amateuristic perspective.
I hope this site is helpful and useful, and feel free to e-mail me anytime if you have any questions or concerns.
