When reading a DNA sequencing gel from bottom to top, you are reading the sequence of the complementary non-coding strand of DNA. This is because the gel displays the sequence of bands corresponding to the bases in the DNA template strand, which is the non-coding strand.
The order of base pairs from top to bottom is the same for each new DNA model. In a DNA molecule, adenine pairs with thymine and cytosine pairs with guanine, forming a consistent sequence. This pairing is fundamental to the structure and function of DNA.
The resulting DNA pattern following electrophoresis is called a gel electrophoresis banding pattern. This pattern shows the separation of DNA fragments based on size as they move through a gel matrix under an electric field. The smaller fragments travel faster and appear towards the bottom of the gel, while the larger fragments move slower and appear towards the top.
Another name for bottom is posterior.
An organism's trophic level in an ecosystem indicates its position in the sequence of energy transfers. Producers are at the bottom, followed by primary consumers, secondary consumers, and so on. The higher the trophic level, the further the organism is from the original energy source.
The bottom is oldest. The top is newest. -From bottom to top is the equivalent of oldest to youngest in an undisturbed sequence.

In undeformed strata, the rocks are typically the densest at the bottom of the sequence. This is due to the process of gravitational settling, where denser rocks sink and accumulate at the bottom over time, creating a denser layering pattern in the strata.
The principle of superposition states that in an undisturbed sequence of rock layers, the youngest will be at the top, the oldest at the bottom.

Top down Program Design : Begins the design with main or top-level module, and progresses downwards to the lowest level modules or subsystem Bottom down Program Design : Begins the design with the lowest level modules or subsystems, and progresses upward to the main program, module or subsystem.
The top number indicates the number of beats per measure, and the bottom number indicates what note value gets one beat.
The oldest layers of sediments are typically found at the bottom of a sedimentary rock sequence, with the youngest layers at the top. Over time, new layers of sediments accumulate on top of older layers, creating a chronological sequence with the oldest layers at the bottom.
