hey dear here your answer;
➡ mutation can be by ultraviolet radiation from the sun, or can occur if a mistake is made as DNA copies itself during cell division.

Hi,
=======:
Here is your answer,
=======:
Mutations arise as a consequence of (at least) two mechanisms:
1. The enzyme that copies the DNA before celldivision is not perfect. Every now and then the wrong nucleotide is incorporated in the newly synthesized DNA strand. If the mistake is not corrected, it can lead to an error in the daughter double-stranded DNA in the next cell
2. Certain chemicals and ionizing radiation can damage the nucleotides in an existing DNA strand. Again, usually these defects are correct by enzymes that can do 'nucleotide excision and repair', but if this doesn't happen timely or correctly, a mutation can occur.

HOPE YOU WILL UNDERSTAND MY WORDS, a request is here please as I am an ACE ranker I wish that to make my way easy for the GENIUS rank you should mark my answer brainlest if you wish then only ☺.
