Students explore chromosome karyotyping. In this chromosome karyotyping lesson plan, students use a chromosome kit to explore chromosome syndromes and disorders. They also produce a large model of a cell with chromosome to simulate cell division, the stages of cell division and the structures of the chromosomes.
High schoolers comprehend that karyotyping is a process in which chromosomes are cut from an enlarged picture and arranged in decreasing order of size. The cells to be viewed are first chemically treated to increase the number of dividing white blood cells and then treated with colchicines to stop mitotic division during anaphase. Lastly, the cells are burst open, stained and fixed. The slide is examined for well spread chromosomes, photographed, and karyotyped.
High schoolers study karyotyping, which is a process in which chromosomes are cut out from an enlarged picture and arranged in decreasing order of size. They use a template to arrange and glue chromosomes to data sheet, indicate sample code, chromosome abnormality and sex of sample.
"More Mutations" has more quality packed into one worksheet than most. Junior geneticists are queried about different types of mutations, mutagens, changes in DNA sequences, and more. Space is provided for them to write their answers right on the page. Highlights of this assignment are a set of color graphics representing mutated chromosomes for learners to identify and a picture of a karyotype for them to read. This makes a well-rounded review that you can assign as homework.
