It is divided into four subunits: Subunit 1A is interpreted as a lowstand systems tract, 1B and 1C are interpreted as a transgressive systems tract, and Subunit 1D is interpreted as a highstand systems tract.
Based on a detailed analysis, this unit was divided into two subunits.
The Mid-Miocene top (R3) is overlain by unit U3, which is further divided into two subunits, namely U3a and U3b.
Subsequently, he discovered that influenza virus could be divided into two subunits by treatment with ether or detergents: haemagglutinin and soluble antigens.
Three units were also confirmed by direct lithological observations of cuttings retrieved by the riser drilling, and from these data, units IV and V were further divided into five and two subunits depending on the content of sandstones.
A sharp upper boundary separates it from a massive layer of loamy carbonate sand (0.60 0.35 m b.s)., which is divided into three subunits: (i) a lowermost normally graded sequence with shells and shell fragments (0.60 0.50 m b.s).; (ii) a coarsening-up sequence (0.50 0.43 m b.s).

The process is catalyzed by a large RNP, ribosome, which is divided into two subunits, large and small, each with the set of well-defined functions.
Closer sequence examination revealed that Bag530 repeats could be further divided into three shorter subunits of 119 bp (A), 276 bp (B) and 120 (A'), respectively: A and A' subunits showed 73.2% of sequence similarity between them.
Subsequently, the 61 APC subunits were divided into five phylogenetic groups of ortholog genes.
