What is a random change in DNA called?

Answer 1

Mutations are random changes in the sequence of bases in DNA. The word mutation may make you think of Ninja Turtles, but that's a misrepresentation of how most mutations work. First of all, everyone has mutations. In fact, most people have dozens or even hundreds of mutations in their DNA. Secondly, from an evolutionary perspective, mutations are essential. They are needed for evolution to occur because they are the ultimate source of all new genetic variation in any species.

Answer 2

A random change in DNA is called a mutation. Mutations can occur naturally during cell division, exposure to environmental factors like radiation or chemicals, or errors in DNA replication. These changes can lead to genetic variation and may have different effects on an organism.

Answer 3

A random change in DNA is called a **mutation**. Mutations are alterations in the DNA sequence that can occur spontaneously during DNA replication, or they can be induced by external factors such as radiation, chemicals, or viruses. Mutations can lead to variations in traits among individuals and are a driving force of evolution. They can range from single nucleotide changes (point mutations) to larger deletions, insertions, or rearrangements of DNA segments.

Answer 4

A random change in DNA is called a mutation.

Points:

• Mutation: A change in the DNA sequence that can occur spontaneously or due to environmental factors.

• Types: Mutations can be substitutions, insertions, deletions, or duplications.

• Effects: Mutations can be beneficial, neutral, or harmful to the organism.

Answer 5

It is called Mutation . It is a spontaneous change in a chromosome or DNA .
