1. Happy Friday! BELL WORK: Write the questions below AND your answers and highlight/underline key words: 1.What is the product of the process of TRANSLATION? a)A complementary mRNA strand b)Increased production of ribosomes c)A completed protein d)Replacement of disabled nucleotides 2.A mutation is LEAST LIKELY to affect a cell when the mutation – a)Reverses the order of bases in a DNA strand b)Allows the total number of bases in a DNA sequence to remain the same c)Replaces a base with its complementary base d)Produces a codon that codes for the same amino acid as the original codon

3. Cell division: the process in which a cell grows and divides into two identical daughter cells

4. Cell Cycle : the series of events that cells go through to grow and divide. Made up of two major phases: Interphase & M Phase Used for organism growth and damage repair Results in 2 identical cells

5. G 1 Phase S Phase G 2 Phase

6. Interphase: Majority of a cell’s life Includes 3 phases (G1, S, G2)

7. G1: cell increases in size, makes new proteins and organelles.

8. S phase: DNA is replicated (copied)

9. Turn to your partner and discuss… WHY does the DNA have to replicate before the nucleus and cell divide?

10. G2 Phase: the organelles and proteins required for cell division are produced. When the G2 phase is complete, the cell is ready to divide.
