1. 
   Mutation
   A mutation is basically a 'typo' that can sometimes occur when cells replicate themselves. Some factors such as certain chemicals, as well as radiation, can cause more mutations than usual to occur.

5. 
   mutation
   A stable, heritable change in the nucleotide sequence of a genetic nucleic acid (DNA, or RNA in viruses, viroids, etc) typically resulting in the generation of a new allele and a new phenotype.

7. 
   Mutation
   A suddenly occurring heritable change in DNA. Such mutations may be brought about by chemical or physical agents (mutagens) e.g. U.V. radiation. An abrupt appearance of a new characteristic in an individual as a result of an accidental change in genes or chromosomes.

8. 
   mutation
   (Variation and inheritance) an error in DNA replication which results in a change in an organism's genetic blueprint. Some mutations are random, others are caused by environmental factors

9. 
   Mutation
   a change in the order of nucleotide bases on a gene, which alters the configuration of the protein produced, and thus may alter the behaviour of the cell. A mutation may cause a cell to die, or become cancerous. Mutations in bacteria and viruses help them to evade detection by their hosts.

12. 
    Mutation
    A chemical change in the DNA in the nucleus of a cell. Mutations in sperm or egg cells or their precursors may lead to inherited effects in children. Mutations in body cells may lead to effects in the individual.

14. 
    mutation
    Any relatively stable heritable change in genetic material that may be a chemical transformation of an individual gene (gene or point mutation), altering its function, or a rearrangement, gain or loss of part of a chromosome, that may be microscopically visible (chromosomal mutation). Note: Mutation can be either germinal, and inherited by subsequent generations, or somatic and passed through cell lineage by cell division.

    Mutation
    A change in a gene. Genes are really codes that tell a cell to make a particular protein. If a gene is mutated, the protein it makes will be abnormal. Mutation can also alter how a gene works by permanently switching it on or off.

    Mutation
    Mutation: A permanent change, a structural alteration, in the DNA or RNA. In humans and many other organisms, mutations occur in DNA. However, in retroviruses like HIV, mutations occur in RNA which is the genetic material of retroviruses. In most cases, such changes are neutral and have no effect or they are deleterious and cause harm, but occasion ...
