A laboratory compared two populations of cells after transient nutrient deprivation. Population 1 entered a quiescent state and showed low cyclin levels; upon nutrient repletion, cells re-entered the cycle. Population 2 carried a mutation that constitutively activates a G1 cyclin-CDK complex and did not enter quiescence under the same deprivation. Which phase is most likely bypassed in Population 2 under nutrient-poor conditions?
