Types of
Mutations
- Gene mutations
- Is a permanent alteration in the DNA sequence
that makes up a gene, such that the sequence
differs from what is found in most people.
- Point Mutations
- Example:
Sickle-cell anemia
- Example:
Sickle-cell anemia
- Point Mutations
- Example: Down
syndrome and
Turner syndrome.
- Is a permanent alteration in the DNA sequence
that makes up a gene, such that the sequence
differs from what is found in most people.

- Factors that causes Mutations
- Replications errors
- Results from the covalent addition of an incorrect
nucleotide subunit, or the lack of addition of a
nucleotide subunit, during polymerization of the
growing newly synthesized DNA strand during
replication.
- Mutagens
- Are chemical compounds or forms
of radiation (such as ultraviolet (UV)
light or X-rays) that cause
irreversible and heritable changes
(mutations) in the cellular genetic
material, deoxyribonucleic acid
(DNA)
- Example: Viruses, Bacteria,
Transposons
- Example: Viruses, Bacteria,
Transposons
- Are chemical compounds or forms
of radiation (such as ultraviolet (UV)
light or X-rays) that cause
irreversible and heritable changes
(mutations) in the cellular genetic
material, deoxyribonucleic acid
(DNA)
- Example: Cáncer
- Mutagens
- Results from the covalent addition of an incorrect
nucleotide subunit, or the lack of addition of a
nucleotide subunit, during polymerization of the
growing newly synthesized DNA strand during
replication.
- Replications errors
- Chromosomal Mutations
- Are alterations that affect whole chromosomes and whole genes
rather than just individual nucleotides.
- Example: Edward's syndrome or trisomy 18.
Patau syndrome or trisomy 13.
- Example: Edward's syndrome or trisomy 18.
Patau syndrome or trisomy 13.
- Are alterations that affect whole chromosomes and whole genes
rather than just individual nucleotides.
