I'm still somewhat confused about the exact point.

So a Kekkei Mora is essentially a whole, complete set of DNA that encodes a specific ability. Kekkei Genkai are only fragments of this DNA set, and thus only evoke fragments of this power.

E.g. A Sharingan contains the power to alter perception of reality (Genjutsu). A Mangekyou awakens the power to impose one's own reality on others (Tsukuyome, Amaterasu, Kamui, etc). A Rinnegan awakens the power to alter reality itself A Rinne Sharingan awakens the power to alter reality entirely (transporting people), subjectively (Infinite tsukuyome) and to break the barriers between dimensions (the dimensional tear ability).

In a way, the Mangekyou awakens only fragments of a Rinnegan's power (powers tied to death, reality and dimensional traversal).
