What is a mutation?
changing of a gene
The action of multiplying
or altering DNA sequence in a gene, resulting in a new variant or form of that gene. Mutations can occur spontaneously or as a result of exposure to radiation, chemicals, or other environmental factors, and can have a variety of effects on an organism, ranging from no effect to serious health problems or even death. Mutations can be harmful, beneficial, or have no effect at all, and play a crucial role in the evolution of species.

A mutation refers to a change that occurs in the DNA sequence of a gene. It is a fundamental process in the evolution of living organisms. Mutations can occur due to a variety of factors, such as errors during DNA replication, exposure to certain chemicals or radiation, or as a result of environmental factors.
To understand mutations, it's helpful to know that genes are segments of DNA that contain instructions for building and maintaining an organism. DNA is made up of a unique sequence of nucleotides (adenine, cytosine, guanine, and thymine), and these nucleotides provide the code that determines the traits and characteristics of an organism.
When a mutation happens, a change occurs in the DNA sequence of a gene. This alteration can affect the instructions provided by the gene, potentially leading to differences in the traits or characteristics of an organism. Mutations can be classified into different types, including point mutations (where a single nucleotide is changed), insertions or deletions (where one or more nucleotides are added or removed), or rearrangements of larger segments of DNA.
To study mutations or determine if a mutation is present, scientists use various techniques, such as DNA sequencing or genetic testing. These methods involve analyzing the DNA sequence to identify any changes or differences compared to a reference or normal sequence.
In summary, a mutation is a change that occurs in the DNA sequence of a gene and can lead to variations in the traits or characteristics of an organism. Scientists can study mutations using techniques like DNA sequencing to understand their effects and implications.
