Saturday DNA!

Come to the science scene on Saturdays!
Enzymes in Action
Mitochondrial DNA Analysis
and Driving Evolution!

Add some DNA to your day . . .

All sessions are two hours long: 10:00 am – 12:00 pm. Chaperones fully participate in all program activities.

Sessions are $21.00 per person ($42.00 for a participating student and accompanying chaperone.)

The sessions are held at the Dolan DNA Learning Center at 334 Main Street, Cold Spring Harbor, NY 11724. (Directions to this location.)

Please note we now have a new method of registration and payment using Eventbrite!

  • Seats for each session are awarded on a first-come, first served basis. We do not accept walk-ins.
  • All seats, in every session, must be reserved using Eventbrite.
  • The name, address, and phone number of each ticket purchaser and/or chaperone and the names and ages of each minor registrant must be included on your Eventbrite registration. We will not honor reservations that fail to provide this information. If you do not provide this information, your reservation will be cancelled and your registration fee will be refunded.
  • The appropriate age for each student chaperone is 18 or over.
  • Once you are registered and payment is made, you will receive an email which will be your entry ticket.

Saturday, January 7, 2017 SESSION CANCELED

Enzymes in Action

10:00 am – 12:00 pm
Ages 10 – 13; chaperone required

Enzymes are proteins that catalyze, or speed up, chemical reactions. Factors we might consider minor details such as temperature or pH sometimes greatly influence the rate at which enzymes perform. Changes in these variables can push some enzymes to the limit, while others simply stop working. Join us to design an experiment that will test the effect of environmental factors on enzyme activity.

In this session, participants will:

  • learn about lactose intolerance and the enzymes involved in milk digestion;
  • digest lactose sugar in milk with lactase enzymes;
  • design an experiment to alter the enzymatic reaction rate.

Mitochondrial DNA Analysis

10:00 am – 12:00 pm
Ages 14 – Adult; under 15 years chaperone required. Chaperones must be 18 or over and fully participate in all program activities.

In this lab students will extract and amplify a small region of their mitochondrial (mt) DNA. Because mtDNA is inherited maternally and has a slow mutation rate, it can be used to trace maternal lineages back thousands of years! Participants will learn how to use DNALC online resources to compare their own mtDNA to other modern humans and ancient relatives, including Ötzi the Iceman, to examine human evolution and migration from a genetic perspective.

In this session, participants will:

  • use Polymerase Chain Reaction (PCR ) to amplify their own DNA;
  • learn how DNA is sequenced;
  • explore the story of Ötzi the Iceman;
  • compare mtDNA sequences to investigate human history.

Driving Evolution

10:00 am – 12:00 pm
Ages 10-13, chaperone required. Chaperones must be 18 or over and fully participate in all program activities.

Since it arose billions of years ago, life has continuously been changing. What are some of the forces driving these changes? Come and investigate the processes driving evolution.

In this session, participants will:

  • learn the forces of evolution;
  • “become the predators” to understand the role of prey selection and survival of the fittest;
  • explore theories underlying the development of the human branch of the tree of life.
