The process described in the question is bottom-top processing that progresses from the sense organs before moving up to the brain.
Top-down processing is one of the 2 general processes of how sensation and perception of sensory information is being processed in the mind. Top-down processing refers to the process pattern of forming perception based on your cognition, or what the brain already knows or expects. Meaning is formed based on a given context that is already known, as well as from general to specific. It involves the processing of sensory information from the brain down to other sensory organs.
For example, our prior knowledge of the spelling of LOVE would make us pronounce and assume LOV3 as LOVE, when someone writes it that way. Without much thought, we quickly take LOV3 to mean LOVE.
Restriction enzymes identifies specific sequences in the DNA (Deoxyribonucleic acid) and cut the DNA to produce fragments. These enzymes are used in the production of the recombinant DNA. These enzymes cut out the specific required fragment of the DNA, which is then incorporated into the bacteriophage. This recombinant phage DNA then infects the bacterial cell, which produces new particles with this foreign recombinant DNA.
