Nucleic acids:

Nucleic acids, such as DNA and RNA, are the genetic material that stores information in the form of genes. They serve as blueprints for building proteins and transferring information for the creation of new cells and the next generation. Nucleic acids are composed of nucleotide chains, which are linked together to form DNA's double helix or RNA's single-stranded structure. The pairing of bases allows for the copying of DNA through replication. Discover more about these essential molecules and their functions.

Presentation Transcript

  1. Nucleic acids: Information molecules

  2. Nucleic Acids Examples • DNA • DeoxyriboNucleic Acid • RNA • RiboNucleic Acid RNA

  3. proteins DNA Nucleic Acids • Function: • genetic material • stores information • genes • blueprint for building proteins • DNA  RNA  proteins • transfers information • blueprint for new cells • blueprint for next generation

  4. sugar N base phosphate Nucleic acids • Building block = nucleotides nucleotide – nucleotide – nucleotide – nucleotide • 5 different nucleotides • different nitrogen bases • A, T, C, G, U Nitrogen basesI’m the A,T,C,G or Upart!

  5. sugar sugar sugar sugar N base N base N base N base phosphate phosphate phosphate phosphate Nucleotide chains • Nucleic acids • nucleotides chained into a polymer • DNA • double-sided • double helix • A, C, G, T • RNA • single-sided • A, C, G, U strong bonds RNA

  6. DNA • Double strand twists into a double helix • weak bonds between nitrogen bases join the 2 strands • A pairs with T • A :: T • C pairs with G • C :: G • the two strands can separate when our cells need to make copies of it weak bonds

  7. Copying DNA • Replication • copy DNA • 2 strands of DNA helix are complementary • they are matching • have one, can build other • have one, can rebuild the whole

  8. 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

  9. 1953 | 1962 Watson and Crick … and others…
