MUTATIONS
Genes can be altered due to un expected and random changes - MUTATIONS: sometimes they can be harmful to individuals.
Types:
The rate of mutations increases when an organism is subjected to agents known as MUTAGENS.
Genes can be altered due to un expected and random changes - MUTATIONS: sometimes they can be harmful to individuals.
Types:
- Gene mutations (alteration affects the chemical structure of DNA)
- Chromosome mutations (alternation affects the structure of de chromosomes)
- Numerical mutations (alternation affects the number of chromosomes)
The rate of mutations increases when an organism is subjected to agents known as MUTAGENS.
- Physical mutagens: Radiation can damage the genetic material (x rays; Radiation from radiactive process)
- Chemical mutagens: Certain pollutans can cause changes in genes.
- Biological mutagens: viruses (they interfere with the genetic material)
