What process(es) occur during the G1 phase of the cell cycle? Nuclear DNA replication occurs. Intense synthesis of molecules and structures. Chromatids are precisely separated; two resulting cells get the same chromosome number. The cytoskeletal structures needed for mitosis arise and chromosomes are condensed.

SUMMARY: ANSWER THE FOLLOWING QUESTIONS 1. The first part of the cell cycle is called __________ 2. During S phase the cell's__________is duplicated. 3. __________ is considered nuclear division since the focus is upon the genetic material of the cell. 4. The first part of this process is called __________ 5. During this phase the__________begin to disappear. The chromatin pulls together and forms pairs of rope like structures consisting of 2 sister __________ 6. These pairs are held together by a structure called the __________ 7. __________ fibers also begin to appear. 8. __________begins when the chromatid pairs line up along the center of a cell. 9. __________is the stage where the chromatid pairs split and the spindle fibers contract pulling each chromosome towards its pole. 10. __________ begins as the cell begins to divide. 11. This split is called __________

1. Which of the following occurs during the G1 phase of the cell cycle? a. all of these answers are correct b. the cell synthesizes various enzymes that are needed later on for DNA replication c. the cell grows d. the cell completes preparation for replication of DNA e. the G1/S checkpoint is reached at the end of the G1 phase 2. If you were to chemically treat a cell, causing it to skip only S phase, the resulting cell would ____. a. Be larger in size and have twice the amount of DNA b. Be the same size and have the same amount of DNA c. Be the same size and have half the amount of DNA d. Be smaller in size and have the same amount of DNA

A. G0 Phase B. G1 Phase C. S Phase D. G2 Phase E. Interphase F. Mitosis G. Cytokinesis DNA replication, or synthesis, occurs during this phase. One cell splits into two cells during this phase. This phase is characterized by cell growth, organelle duplication, and protein synthesis. This phase includes all the phases except mitosis and cytokinesis. This phase includes a series of events that a cell undergoes leading up to cell division. This phase follows the S phase. In this phase, cells are not actively progressing through the cell cycle. These cells are sometimes described as existing in a resting stage.
