This worksheet can be used to introduce the topic of chromosomes, genes and DNA (with teacher explanation) or could be used as part of a recap lesson. All cells in an organism have the same genetic content, but the genes used (expressed) by the cell may be regulated in different ways. Genes are parts of DNA so genes are located in DNA. The first is by changing the gene's position on the chromosome to bring it very close to expanses of centromeric heterochromatin, thereby increasing the likelihood for interaction. Example tasks.
