The DNA Store is a part of the in-game main menu where you can buy DNA via Robux and see your current DNA. After every 12 hours, you can get a ‘daily bonus’ of 
100. This allows up to an additional 200 a day, so it is recommended you collect the bonus whenever you can. The store is available on all maps, including the trading map, making it useful as an expensive “Top-up” on DNA. DNA is purchasable using Robux.

Information
Considering that 1 ROBUCK is essentially worth $0.01 USD, 17250 for 4000 means the maximum efficiency will get you 431 for every dollar you spend. Likewise, the minimum efficiency at 10 for 4 gets you only 250 for every dollar you spend. Because of this, many players recommend against buying DNA with Robux. As you can easily get that much DNA with just farming a 25 day old Barosaurus for a couple minutes. Check the Growth Rate Multiplier Chart for more information on growth times and DNA earned per day. Even so, the prices can be considered “unreasonable” unless you have a lot of Robux, but it is still not recommended unless you are desperate to get a skin or dinosaur that will become unavailable soon.
You can also spend Robux to get DNA with the Party Box Gift by pressing the P key, which costs 40. However, please note that it only gives everyone except you free DNA.
Trivia
- As of June 25, 2018, there is an event where you get a bonus +150 daily DNA everytime you check in, giving
250 every time. It was originally going to last for a week but is still ongoing.
