If you’re a Genesis Ark, you can have foreign DNA introduced to your system, and your system will simply copy and store it indefinitely. Then if you ever reach a splicing station, you will gain the ability to clone the creatures that you have the DNA of. However, you need the entire genetic sequence to clone the creature, and not just a few lines.
Splicing Station-Splicing Stations were set up ages ago during the great rush to find the first ever being. Scientists would capture a specimen, extract its DNA, and then clone it so they could show it off to their pals.
Splicing Stations can be found anywhere with an emphasis on genetics or defunct research labs.
