Simply stated, a mistake made while DNA copies causes changes in DNA.

One of the most powerful agents of genetic change?

is mutation. Mutations can occur spontaneously, through errors in DNA replication, or can be induced by environmental factors such as radiation or chemical exposure. These changes in DNA sequence can lead to alterations in the genetic code and can have a wide range of effects, from beneficial adaptations to harmful disorders.

Change in the nucleotide sequence of DNA?

Mutation. Either exchanging a Purine with another Purine, Pyrimidin with another Pyrimidin, or completely exchanging a Purine with a Pyrimidin or vice versa. Point- or Frameshift-Mutation.


What is recombinant sequence?

A recombinant sequence of DNA is a sequence of DNA that comes from more than one source. Examples of recombinant DNA are plasmids that are put into bacteria. The plasmid comes from the bacteria (or a bacteria at least) but a target gene has been added (say the lac operon gene that allows bacteria to thrive on lactose), this plasmid is now a recombinant DNA sequence.
