TLF ID L5917

See how genes and genetic engineering work. Build models of DNA, and work out how it is copied as cells divide. Discover how the codes carried in the genes are copied and used to build proteins. See how gene splicing can be used to benefit human lives. For example, model the transfer of a human gene into bacteria, so they produce insulin. This learning object is a combination of five objects in the same series. The objects progressively increase in difficulty.

Educational details

Key learning objectives
  • Students locate the structures responsible for genetic coding in organisms.
  • Students model the construction of the complementary strands of a DNA molecule by pairing nucleotides.
  • Students model DNA replication and the action of helicase and DNA polymerase.
  • Students model the transcription process to construct mRNA from DNA.
  • Students use the triplet code to model the construction of proteins from mRNA.
  • Students model the transplantation of genes from one species to another.
Educational value
  • Introduces and models DNA structure and genes, including pairing of nucleotide bases.
  • Introduces and models DNA replication and transcription, protein synthesis, and gene splicing.
  • Requires students to participate in modelling DNA structure, replication, transcription, protein synthesis, and gene splicing by making appropriate selections.
  • Provides structured feedback to user input.
  • Includes audio help for pronunciation of unfamiliar terms.
  • Includes end-of-section quizzes to test understanding.
