structural mutation have four types of change in the chromosomal structure: TRANSLOCATION, INVERSION, DELETION AND DUPLICATION.
while:
numerical mutation results from nondisjunction, or the failure of a pair of homologous choromosomes or a pair of sister chromatids to separate during meiosis or mitosis. The effect of nondisjunction during mitosis is not harmful as the effect of nondisjunction during meiosis.

What can cause changes in DNA sequences?
mutations
Mutations that occur at random are called?
Mutations that occur at random are called spontaneous mutations.
What is spontaneous and induced mutations?
Mutations which are artifically induced with the help of mutagenic agents are called induced mutations
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 various kinds of mutations?
Mutations differ and change according to many factors: 1- Site of occurrence: -Genetic mutations -Chromosomal mutations 2- The inheritance: -Somatic mutations -Gamete mutations 3- The origin: -Spontaneous (natural) mutations -Induced mutations 4- The harmful OR useful effects: -Undesirable mutations -Desirable mutations
How can a mutation ouccur?
mutation occurs throughchange in structural chromosomes.change in numerical chromosomes.gene mutation
What are the raw material of evolutionary change?
Mutations are considered as the raw materials of evolutionary change. They are structural changes in the DNA sequence of an organism.
Are mutations predictable?
No, they are random, This means that they occur in no set numerical order. So, though they can not be predicted it is certain, with the mistakes made in replication and other factors, that they will occur.
What can cause changes in DNA sequences?
mutations
Changes in DNA are called mutations?
the answer is mutations.......................
Are all mutations bad.?
No not all mutations are bad there are good mutations and bad mutations
How do you spell mutations?

Genetic information is alterd when changes in the DNA sequence is called?
It is called mutations. I'm 100% sure.
What two types of chromosomal mutations?
Two are insertion mutations and deletion mutations.
What are known as gene mutations and occur at a single point in the DNA sequence?
Mutations that occur at a single point in the DNA sequence are Point Mutations.
Mutations that occur at random are called?
Mutations that occur at random are called spontaneous mutations.
What is spontaneous and induced mutations?
Mutations which are artifically induced with the help of mutagenic agents are called induced mutations
