Interphase

• what is interphase?


  the longest phase of the cell cycle, with much metabolic activity, where the cell starts to get ready for division
• what happens during interphase?

  • the newly formed cell grows and its organelles replicate, replacing those lost in the previous division
  • the DNA replicates so its quantity doubles
  • proteins (e.g. histones and enzymes) are synthesised during interphase, requiring energy from ATP
  • the chromosomes are not visible in the microscope because the nuclear material, chromatin, is dispersed throughout the nucleus
• what is the ‘s’ phase?

  • its the synthesis phase
  • this is where the DNA is replicated
• what is the status of the cells in interphase?

  they are biochemically very active
