A clear lesson on the structure of DNA. It explains the double helix, nucleotides and complementary base pairing, then shows how the order of bases forms a code and how a gene codes for a protein. It ends with a flow chart task linking DNA, genes, proteins and traits.
What this presentation covers
- the double helix
- nucleotides: phosphate, sugar and base
- the four bases A, T, G and C
- complementary base pairing
- the genetic code
- genes and proteins
- flow chart task: DNA to gene to protein to trait
