You have the technology necessary to measure each of the following in a sample of animal cells: chlorophylls, organelle density, picograms of DNA, cell wall components, and enzymatic activity. Which would you expect to increase significantly from M to G₁?
A) organelle density and enzymatic activity
B) cell wall components and DNA
C) chlorophyll and cell walls
D) organelle density and cell walls
E) chlorophyll and DNA

During the G₁ phase of the cell cycle, cells are focused on growth and preparation for DNA replication in S phase. This means that the organelle density would increase as the cell grows and prepares for cell division, and enzymatic activity would also increase as the cell prepares to replicate its DNA. Cell wall components, picograms of DNA, and chlorophylls would not necessarily see a significant increase during this phase.
