- Genes are sections of genetic material located in specific areas on chromosomes.
- Mutations in chromosomes can make proteins incorrectly.
Why Do We Need To Know About Chromosome
Learning about chromosomes helps us understand how life is built at the genetic level, which is very important for many jobs in science. For example, forensic scientists use DNA, which makes up chromosomes, to solve crimes by finding special genetic markers that everyone has differently. They make a lot of copies of the DNA to spot changes that can point to a criminal. This shows how knowing about chromosomes is used in solving crimes.
In the same way, scientists who study viruses need to know about chromosomes and how they can change. This helps them track how viruses change over time, create treatments, and handle outbreaks, which can save many lives. These examples show that understanding chromosomes is important in jobs that help keep people healthy and safe.
