(3) The evolution of organelles and compartmentalization in human cells due to the following advantages/benefits: A) Higher concentrations of substrates for enzymes due to the confinement of molecules in a much smaller volume; B) Rapid diffusion of water molecules across the cell; C Division of labor (specialized organelles for specific/dedicated purposes or functions); D) Separation of the transcription and replication processes; E) No benefits in having organelles in human cells. (4) Decoding the human genome. A) All genes are transcribed in a human cell regardless of cell types (e.g. neuron and liver cells); B) Both corresponding genes in each chromosome pair are always transcribed equally; C) All genes encode functional protein molecules; D) Each cell type has a different set of RNA and protein molecules; E) In theory, the Y chromosome is not essential (for the creation or function of a human).
