A Cell is an item added by Advanced Genetics. It is used as a basic starting item for the mod. Every Cell is for a specific entity and that entity only. They cannot be converted or changed. Cells will not stack, even if they are from the same entity—items that provide extra inventory space are recommended.
When a Cell has been acquired, place it in a DNA Extractor to acquire a Helix (Encrypted). This Helix (Encrypted) can be placed into a DNA Decrypter to decrypt the it and continue the process of obtaining an ability for the player.
