Each group is given a long paper strip of DNA, the story of the missing necklace and directions on how to fingerprint and sequence their DNA. Scissors act as the restriction enzyme, cutting the DNA between every CCGG into varied length segments. As the segments are pasted into the corresponding rows on the sequencing board (imitating gel electrophoresis), the DNA fingerprint of each suspect will emerge. So, who stole the necklace? Be a crime stopper!
This bundled unit contains at least 2 weeks of teaching materials or 3 weeks if you complete all of the enclosed labs. The title of this unit is DNA, RNA and Protein Synthesis. This unit has everything that a teacher needs to teach a unit on this topic to Biology or life science students. It covers: The history of DNA discoveries, the structure of DNA, replication, transcription, and translation / protein synthesis.
Chromosome: an organized structure of DNA and protein that is found in cells; a single piece of coiled DNA containing many genes, regulatory elements and other nucleotide sequences; also contain DNA-bound proteins, which package the DNA and control its functions; responsible for transmitting genetic info; chromosome theory of inheritance: carriers of genes
What Are Epigenetic Effects? Epigenetic effects (individually called epigenetic markers) are reversible, heritable changes to the way the body interprets and expresses its genetic code (DNA). Epigenetic effects occur without changing the DNA sequence (i.e., without changing genotype).
Deletion of Any Single Gene Provokes Mutations Elsewhere in the Genome: Findings call for a rethinking of cancer genetics. Johns Hopkins researchers report that the deletion of any single gene in yeast cells puts pressure on the organism’s genome to compensate, leading to a mutation in another gene.
