  • Introduction
  • Eukaryotic Chromosomes
  • The Cell Cycle
  • the existence of the 3 distinct interphase periods was found using thymine nucleotides labeled with radioactive H
    • cells that enter mitosis in the first few hours after being given labeled thymidine do not contain radioactive DNA
    • cells entering mitosis somewhat later do show radioactivity in their DNA
  • RNA production and protein synthesis fluctuates slightly in the cell cycle
  • some proteins are made continuously, whereas others are made only during certain parts of the cycle
  • histone proteins and DNA synthesis proteins are made in the S period
  • little RNA synthesis occurs (usually) during the S period
  • the length of G1 is the most variable of the periods
  • Cell cycle times
