Mutations can arise from the following:
Substitution- one base is inserted for another.
Deletion- a base is removed, which causes a frame shift drastically changing the codon sequence.
Insertion- a base is added to the sequence, which also causes a frame shift.
Translocation-group of bases are moved some place else in the genome. This results with altered function.
Tansposable elements- genes move from one location in the genome to another. This may happen in coding or non-coding regions.
Inversion- a segment of chromosome is reversed in its orientation and has significant effect on gene expression

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
What can occur for limited gene flow?
Mutations can occur in gene processing errors.
Mutations that occur at one single nitrogen base are referred to as?
Mutations that occur at one single nitrogen base are referred to as a point mutation.
What does a positive cell voltage mean?
The reaction is spontaneous.
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
What is spontaneous mutations?
in the nucleus
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.
Common mutagenic agents include?
In genetics, a mutagen (Latin, literally origin of change) is a physical or chemical agent that changes the genetic material, usually DNA, of an organism and thus increases the frequency of mutations above the natural background level. As many mutations cause cancer, mutagens are therefore also likely to be carcinogens. Not all mutations are caused by mutagens: so-called "spontaneous mutations" occur due to spontaneous hydrolysis, errors in DNA replication, repair and recombination. This is from wiki hope it helps
Mutations in DNA often occur during replication During which phase of the cell cycle do such mutations occur?
Interphase
Is bacteria a asexual organism?
Yes. Bacteria cells reproduce by a process called binary fission. The daughter cell is genetically identical to the parent cell (unless spontaneous mutations occur during division).
What are mutations that occur at a single point?
Such mutations are called point mutation or gene mutation.
Can mutations occur in jellyfish?
Mutations happen in ALL living things (and also in viruses)!!!!!!
Are mutations in the DNA sequence gene transient changes?
Successful mutations will persist. Mutations usually occur during replication. Some mutations will flourish depending on environmental factors.
What is a facets of life?
Mutations that occur in DNA
Is it true that only mutations in gametes can be passed from parent to offspring?
Gametic mutations occur in the cells of the gonads (which produce sperm and eggs) and may be inherited. There are two types of mutations that can occur in gamete cells: 1. Gene Mutations 2. Chromosomal Mutations
