Nucleic Acids

• Examples
• ____________
• DeoxyriboNucleic Acid
• ____________
• RiboNucleic Acid

3
Nucleic Acids

• Function
• genetic material
• _________________________
• genes
• blueprint for building proteins
• DNA ? RNA ? proteins
• _________________________
• blueprint for new cells
• blueprint for next generation

4
Genes (DNA)are needed to run bodies every
day to make you and meto make new cells to
make babies!

DNA

• Double strand twists into a double helix
• _______________ between nitrogen bases join the 2
  strands
• ___________________
• A T
• ___________________
• C G
• the two strands can easily separate when our
  cells need to make copies of it

_____________
8
Copying DNA

• _____________________
• copy DNA
• 2 strands of DNA helix are _______________________
  
• they are matching
• have one, can build other
• have one, can rebuild the whole

9
DNA replication

• Copying DNA
• pairing of the bases allows each strand to serve
  as a pattern for a new strand

Newly copied strands of DNA
