INTERPHASE
• 3 PARTS OF INTERPHASE:
• G1: REPLICATING ORGANELLES
• S: REPLICATING CHROMOSOMES
• G2: CHECKS FOR ERRORS/PREPARES
FOR MITOSIS
• LET’S ZOOM IN ON S-PHASE!
SYNTHESIS PHASE: DNA COMPONENTS RECAP
• DNA is composed of nucleotides
_________.
Deoxyribose sugar and the ____________are
• The _________________
always the same.
phosphate
The component that differs is the nitrogenous bases (or nitrogen
base).
BASE PARIRING RULES
Thymine
• Adenine always pairs with __________.
Guanine
• Cytosine always pairs with __________.
SYNTHESIS PHASE: DNA REPLICATION RECAP
• Replication: Synthesizing (making) DNA
Remember!
• The nitrogen bases are separated by weak,
_________________
bonds being broken
hyrdogen
apart.
• The sugar and phosphate molecules are held
covalent
together by strong, _________________
bonds.
Let’s Practice! Try to sing the
song with your eyes closed. Only
look if you have to!
We love DNA
made of nucleotides.
Phosphate, sugar, and a
base
bonded down one side.
Thymine and adenine
make a lovely pair,
cytosine without guanine
would feel very bare.
Try your best to circle the correct answer to
the 4 statements below on your paper.
1. Mitosis occurs in:
Somatic cells Gametes
2. Mitosis creates daughter cells that are genetically:
Different
Identical
3. How many divisions occur during the process of mitosis?
One
Two
4. How many daughter cells are created as a result of mitosis?
Two
Four

PHASES OF MITOSIS RECAP
CELL CYLCE AND MITOSIS IN SUMMARY:
Let’s Practice!
• For each picture, write the following things on your
whiteboard.
• Use your spinner to help you!
1. The phase the cell is in.
2. The defining
characteristic of that
phase.
1. The phase the cell is in.
2. The defining
characteristic of that
phase.
1. Metaphase
2. Lined up in the middle
1. The phase the cell is in.
2. The defining
characteristic of that
phase.
1. Interphase
2. No defined chromosomes
1. The phase the cell is in.
2. The defining
characteristic of that
phase.
1. Telophase
2. Daughter cells are
pulling apart from
each other, but not
completely
separated.
