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)
b)
c)
d)
A complementary mRNA strand
Increased production of ribosomes
A completed protein
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

Cell division: the process in which a cell grows
and divides into two identical daughter cells
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
G1 Phase
S Phase
G2 Phase
Interphase:
• Majority of a cell’s life
• Includes 3 phases (G1, S, G2)
G1: cell increases in size, makes new
proteins and organelles.
S phase:
DNA is
replicated
(copied)
Turn to your partner and
discuss…
WHY does the DNA have
to replicate before the
nucleus and cell divide?
G2 Phase: the
organelles and
proteins required for
cell division are
produced.
When the G2 phase is
complete, the cell is
ready to divide.
