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
What causes genetic mutations?
Mutations are changes in the nucleotide sequences in a genome. Most often, these minor mistaks are corrected by in-built repair mechanisms and many mutations go unnoticed an are not harmful. Harmful mutations cause diseases in many cases. There are several factors that promote the formation of mutations. These factors are called mutagenic agents. Mutagenic agents are divided into: chemical and physical mutagens. UV radiation is an example of a physical mutagen and Nitrous acid is an expample of a chemical mutagen

Changes in DNA are called mutations?
the answer is mutations.......................
At which point in the eukaryotic cell cycle can a DNA mutation occur?
Synthesis. The DNA replication process can contain copying errors that may not be corrected. Most are neutral, some are deleterious and some may be beneficial mutations.
Are all mutations bad.?
No not all mutations are bad there are good mutations and bad mutations
How do you spell mutations?
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
