How does mutation affect DNA replication?

A mutation is a random change in the genetic sequence of DNA. Examples of such mutations include point mutation (such as addition or deletion of bases). Errors in DNA replication can actually cause these mutations. If a mutated sequence is then replicated, this could cause incorrect proteins to be made (due to errors in the primary sequence).

Biology tutor with 4 years of experience. Medical student with a BA in biochemistry

I am currently a 4th year medical student studying at the University of Cambridge. I have previously obtained a BA in biochemistry and have 4 years of tutoring experience. My style revolves around a dialogue with students to help them understand topics through first principles, not just to learn a topic through a textbook.
