Imagine a pair of dragons that produce offspring and determine the percentage of the hatchlings have wings and large antlers. This fantastic activity draws genetics learners in, introduces them to alleles, meiosis, phenotypes, genotypes, and teaches them how to use Punnett squares. The exercises also illustrate the law of independent assortment and linked genes. The handout is ten pages long and will take days to work through, but it will definitely keep learners engaged!
The lecturer starts by emphasizing that the mitotic process is a separate mechanism to cytokinesis - the cytoplasm splitting to become 2 cells. The video continues explaining the stages of mitosis in great detail. Each stage is diagrammed and the relevant structures are labeled and explained. Your students will find this to be a valuable supplemental study tool.
This exercise implores biology learners to think through the phases of mitosis, and gives them a sweet snack at the end! They begin by twisting apart creme-filled cookies and using the icing as a cytoplasm, if you will. Colored candy sprinkles make up chromosome pairs, which learners line up on the icing to model where they appear in each phase. This simple, but engaging activity is sure to make an impression when studying mitosis. Follow-up questions are included.
Three steps are needed to extract DNA from learners' inner cheek cells. The procedure and reasons for each step are explained. As enzymes work on the cells, a series of questions are answered regarding the structure of the DNA molecule. As the third step is in process, questions about DNA replication are also addressed. Finally, the DNA strands are placed into tiny tubes and hung on necklaces for biologists to wear home! If you can obtain the tubes, this would be a unique and memorable enrichment.
Students use this laboratory procedure to outline the mechanism by which salivary glands are removed and prepared so that the polytene chromosomes may be observed.Drosophila virilis is used instead of Drosophila melanogaster because D. virilis is much larger and it is easier to dissect and remove the salivary glands from the larvae of this species.
Six different chromosome activites introduce biology aces to heredity, chromosomal abnormalities, sex-linked traits, and the human genome. The hands-on activites are fairly simple for the teacher to prepare and will prove to be both educational and engaging. Use them in your biology class to supplement your genetics unit.
See how the strands of DNA separate and become a template for a replica to be incorporated in a new cell! The microbiology and biochemistry of the process is detailed. This lecture refers to the concepts of transcription and translation when making a protein. These are very involved processes. Consequently, this might be more useful as a supplement to a lesson versus as an independent study. It is also difficult to find this topic relevant to other work because the details can be dry.
