Any sudden change in the genetic material is known as MUTATION.Mutation may occure at GENE LEVEL or CHROMOSOMAL LEVEL.
TYPES:
- Missence mutation.
- Nonsence mutation.
- Sielent mutation.
- Frame shift mutation.

A gene variant is a permanent change in the DNA sequence that makes up a gene. This type of genetic change used to be known as a gene mutation, but because changes in DNA do not always cause disease, it is thought that gene variant is a more accurate term. Mutations can result from DNA copying mistakes made during cell division, exposure to ionizing radiation, exposure to chemicals called mutagens, or infection by viruses.

∙ 13y agoMutations are changes in an organism's DNA that potentially affect the correct functioning of genes.They occur naturally due to replication errors, mispairing of homologous chromosomes, or through unavoidable exposure to natural radiation (e.g., cosmic rays). Mutations can occur anywhere in the DNA and in any cell

∙ 12y agoMutation are sudden heritable changes which give rise to new alternative form of genes i.e gives rise to a new novel phenotype which is somewhat different from genetic recombination. Mutation can be sponataneous or induced .
1. Spontaneous mutation are those which occur in the absence of a exogeneous substance often called as mutagen causes of spontaneous mutation are error in Dna replication,transposition,spontaneous lesions(deamination).
2.Induced mutation are one which are the result of exogeneous substance called mutagen such as ionic radiations,intercalltaing agent,oxidizing agents etc.

Is 'mutations are beneficial to organisms' a true statement about mutations?
Usually mutations have deleterious effects to the organism, but occasionally there are beneficial mutations. Such mutations drive evolution.
What are the changes in DNA sequences that affect genetic information known as?
Mutation
Mistakes in the DNA are called?
for Plato it isn't A or B the answer is D
A mutation involving a chain in the base sequence of DNA?
You might be referring to point mutation. This is when one nucleotide in a gene is changed and causes many irregularities in the cell.
What is the major source of new alleles in natural populations?
either new organisms entered the population from an external source, or there were mutations
What is the natural causes of mutations?
1.)Mutations can be inherited. This means if a parent has a mutation in his/her DNA, then the mutation is passed on to the child.2.)Mutations can be acquired. This happens when a mistake accurs when a cell copies its DNA.3.)Mutations can occur by a hidden gene. This happens when your ancestor(for example, "grandma") has the mutation and that mutation is passed on to every other girl(for example), then the girl will get the mutation.
What is the Difference between a mutant and mutation?
A mutagen is a substance that CAUSES a mutation. Essentially, mutagens are the cause, mutations are the effect. Simple as that :)

What are mutations that occur at a single point?
Such mutations are called point mutation or gene mutation.

Mutation
Mutations that cause dramatic changes in protein structure are often?
your mom is what causes the answer, Frameshift mutation.
Changes in DNA are called mutations?
the answer is mutations.......................

How can a mutation in DNA base sequence causes a change in trait?
Some mutations produce new traits that can help an organism survive.
How do mutations occur in an organism?
In the base sequence of the DNA part of the DNA changes which causes a change in the whole DNA which is called a mutation.
