DNA STRUCTURE
- Nucleotide structure -All
combined through
condensation reaction to form
dinucleotide-
- Pentose sugar - Deoxyribose
- A phosphate
- An organic base
- Single Ring- Cytosine
& Thymine
- Double Ring-
Adenine &
Guanine
- Single Ring- Cytosine
& Thymine
- Pentose sugar - Deoxyribose
- Pairing of Bases
- Contain Nitrogen
- Adenine &
Guanine are
double ring
structures
- Longer
molecules
- Longer
molecules
- Thymine &
Cytosine are
single ring
stuctures
- Shorter
molecules
- Shorter
molecules
- Adenine is
complementary to
Thymine.
- Two
hydrogen
bonds.
- Two
hydrogen
bonds.
- Each rung of DNA
ladder must be the
same length
- Cytosine is
complementary
to Guanine.
- Three
hydrogen
bonds.
- Three
hydrogen
bonds.
- Contain Nitrogen
- Function of DNA
- Very stable and can
pass from generation
to generation
- Strands are joined
by hydrogen
bonds, allows
them to separate
during DNA
replication and
protein synthesis.
- Carries
immense
amount of
genetic
material
- Deoxyribose-phosphate
backbone protects the
genetic information
from being corrupted
by outside chemicals.
- Very stable and can
pass from generation
to generation
