the following letters.
• Each letter may be used multiple times
in the same word.
• No size limit on the word

• EVERY BOOK EVER
WRITTEN; EVERY WORD
YOU HAVE EVER READ IN
THE ENGLISH LANGUAGE IS
JUST A COMBINATION OF
26 LETTERS.
• What is the molecule below?
• What is the molecule below?
NUCLEOTIDE – NUCLEOTIDES ARE THE
BUILDING BLOCKS OF NUCLEIC ACIDS
• What is the molecule below?
NUCLEOTIDE – NUCLEOTIDES ARE THE
BUILDING BLOCKS OF NUCLEIC ACIDS
(DNA,RNA)
• What are the similarities and
difference in the 4 molecule below?
• What are the similarities and
difference in the 4 molecule below?
4 different nucleotides –distinguished by
their unique nitrogen base (A) Adenine;
(C) cytosine; (G) Guanine, and (T) Thymine
• DNA is a double helix – draw a
double helix
• DNA is a double helix – draw a
double helix
• DNA is a double helix – draw a
double helix
• Notice the multicolored “rungs” of
the ladder.
• What do they
represent?
• DNA is a double helix – draw a
double helix
• Nitrogen bases are
the important part
– they represent
the code for
building proteins
Nitrogen BASES= Instructions for Proteins
• Nitrogen BASES= Instructions for
Proteins
• Nitrogen bases are
read in units of 3
called codons
• Each codon
represents 1 amino
acid
• DNA REPLICATION
–Process of making
an exact copy of the
DNA double helix
–Allows cell to
provide a complete
set of instructions
for each daughter
when the cell
divides.
• DNA REPLICATION
–Step 1: The double
helix unzips (nitrogen
base pairs separate)
–Step 2: DNA
Polymerase builds
the new strands on
the existing template
according to
chargaff’s base
pairing rules. DNA
Polymerase also
proofreads and
correct errors.
• Chargaff’s Base
Pairing Rules
• A-T
• C-G
