Most synthesis techniques use a bottom-up approach.

Most biologists working within the modern synthesis assumed that an organism is a straightforward reflection of its component genes.

Most titanium is present in armalcolite in the 4 + state, owing to the reducing synthesis environment, but there is a significant fraction of Ti < sup > 3 +</ sup > in lunar samples.

Most commonly, drugs are organic small molecules produced through chemical synthesis, but biopolymer-based drugs ( also known as biologics ) produced through biological processes are becoming increasingly more common.

Most ( but not all ) placer deposits, because of their shallowly buried nature, are mined by surface methods.

Most PCR methods typically amplify DNA fragments of up to ~ 10 kilo base pairs ( kb ), although some techniques allow for amplification of fragments up to 40 kb in size. The reaction produces a limited amount of final amplified product that is governed by the available reagents in the reaction and the feedback-inhibition of the reaction products.

Most such methods do rely on comparisons between the sequence to be predicted and sequences of known structure in the Protein Data Bank and thus account for environment indirectly, assuming the target and template sequences share similar cellular contexts.
