Exploring the genes, biological functions and genetic conditions associated with Human Chromosome 18. Introduction: Why Is Chromosome 18 Important? Human DNA contains 23 pairs of chromosomes, with one chromosome in each pair inherited from each biological parent. These chromosomes carry the genetic instructions that guide our development, influence our characteristics and help regulate the biological processes that keep us alive. Chromosome 18 is particularly interesting because it contains genes involved in brain development, cellular communication, immune regulation, metabolism, tissue growth and the maintenance of healthy organs. Some important genes located on Chromosome 18 include: Chromosome 18 is also associated with several recognised genetic conditions, including Edwards syndrome (trisomy 18), 18p…
