Cells are able to control genes by turning genes on and off. This process is known as gene expression. Genes are turned on and off in different arrangements to make a stomach cell function differently from a muscle cell or a brain cell.

Gene Mutations

If the sequence of nucleotide bases from the DNA to the RNA is transcribed or translated incorrectly, the protein may not function properly. This error creates a change in the gene sequence or chromosome.

Mutations can be caused by harmful chemical agents, X-rays, high temperatures, and viruses. They can result in altered genes and even extra or missing chromosomes. A physical or chemical agent that can cause a change in DNA is a mutagen.

Mutations that occur in genes can cause conditions known as genetic disorders. Some of the more common genetic disorders caused by gene mutations include cystic fibrosis, sickle cell anemia, and Tay-Sachs disease. On the other hand, some mutations can be beneficial.

The process of turing on and off genes is known as _______.
Question 12
12.

A gene mutation is a permanent change in a gene or chromosome of a cell. The mutation can be a change in the order of bases, number of bases, or types of bases. Mutations may be harmful, be beneficial, or have no effect on an organism at all.

Mistakes can happen when DNA is copied during replication, causing proteins to not work properly. When this happens, it can affect the structure, function, and traits of organisms. Mutations that cause proteins to fail can lead to serious medical conditions or diseases.
