Write one paragraph about how would you teach your family about DNA ... Add one paragraph on how you could do this better in the future.

You might buy a home DNA test kit in a store or order one online. Each kit comes with instructions and materials to collect a swab from the inside of your cheek or a saliva sample.

Collection won't hurt at all and only takes a few minutes, but you're generally advised not to eat, drink, brush your teeth, or smoke for at least 30 minutes before you provide your sample.

After you've finished your collection, you can simply mail the kit back to the company with a pre-addressed, postage-paid envelope. The kit should also include instructions about how to register for an online account.

Hope it helps!
