Some changes are beneficial, others harmful, and some neutral to the organism.

Understand how base substitutions, like transitions and transversions, lead to point mutations. Discover how insertions and deletions can cause frame-shift mutations. Finally, get a glimpse of large-scale mutations, such as translocation and inversion.

Mutations can be inherited from parents or occur spontaneously due to factors like replication errors or environmental influences. Sickle-cell disease exemplifies how a single amino acid change can impact protein function, leading to health complications.

Point mutations involve the replacement of one base with another.Frame-shift mutations occur when a base is added or removed from the sequence. Non-sense mutations create a stop codon, which can prevent the protein from being produced entirely, while missense mutations result in the substitution of one amino acid for another.
