Final answer:
Jeremy has sequenced genes, which are the units of DNA that contain instructions for making RNA and proteins critical for cellular functions according to the Central Dogma of Molecular Biology.
Step-by-step explanation:
Jeremy has determined the complete chemical sequence of the entire set of human DNA, which means he has sequenced genes. Genes contain the instructions for making proteins or stable RNA molecules, which carry out specific functions in cells. The DNA of a chromosome is encoded with genetic instructions organized into units called genes, and these genes dictate the amino acid sequence of proteins. The entire genetic content of a cell is referred to as the genome.
Furthermore, the Central Dogma of Molecular Biology posits that information in biological systems flows from DNA to RNA to protein. DNA is transcribed into mRNA, which is then translated into protein. Chromosomes are structures that carry genes, and these genes are responsible for the production of RNA and proteins necessary for all of life's processes.
