The document discusses gene mutations and their effects. It defines a mutation as a change in genetic material that can affect chromosomes or genes. Mutations can occur during DNA replication from errors or environmental exposures. There are two main types of mutations - point mutations, which change a single nucleotide, and frameshift mutations, which insert or delete nucleotides, altering the coding. The document provides examples of different mutation types, like missense mutations changing amino acid sequences and nonsense mutations introducing stop codons. It includes an assessment with multiple choice questions testing understanding of mutation concepts.

DNA sequence and its corresponding
effects.

MUTATION
7. It can occur during DNA replication if errors are made and not corrected in
time. Mutations can also occur as a result of exposure to environmental
factors such as smoking, sunlight, and radiation. Often cells can recognize
any potentially mutation-causing damage and repair it before it becomes a
fixed mutation.

MISSENSE SUBSTITUTION
THE BOY CUT HIS FIP AND ATE THE HOT DOG
11. It occurs when a mutation changes
the sequence of amino acids.
MISSENSE SUBSTITUTION
12. THE BOY CUT HIS LIP AND ATE THE HOT DOG
NONSENSE SUBSTITUTION

13. It occurs when a mutation changes an amino acid to
a stop codon. The Ribosomes stop translating and
proteins are not fully made.
NONSENSE SUBSTITUTION
14. THE BOY CUT HIS LIP AND ATE THE HOT DOG
SILENT SUBSTITUTION

15. It occurs when a mutation changes the nucleotide
sequence. However, it still produces the same kind of
protein or amino acid.

19. It occurs when one or more nucleotides are either
removed or inserted which completely changes the
sequence of codons.
