Name two major types of mutations?

Frameshift mutations and Point mutations. The difference between the two are that point mutations occur at a single point in the DNA sequence and frameshift mutations shift the "reading frame" of the genetic message.


Mutations that occur at random are called?

Mutations that occur at random are called spontaneous mutations.


What can occur for limited gene flow?

Mutations can occur in gene processing errors.


When does point mutation occur?

Bacic Answer:Point mutations occur when a single nucleotode is replaced with another nucleotide tide base. Insertion and come in this category.More Detail Answer:Point mutations occur when a single nucleotide is replaced with another nucleotide tide base. Insertion and come in this category. Error in the process of replication of DNA molecule results in point mutations. Sometimes heat of high level radiation cause the error in DNA replication. There are different effects of point mutations. if this type of mutation occurs in the sequence of DNA molecule or exon, then the protein sequence changes present in the gene. If the mutation occurs in the RNA effecting the codon of gene Sickle cell anemia is cause by the point mutations. Changes occur in the beta hemoglobin. it converts GAC sequence into GUG, Point mutation can be subdivided into three types:1) Nonsense mutations are the ones which code for the same amino acid.2) Misssense mutations occur in the genes which code for different amino acid.3)Silent mutations do not affect the function of the protein and code for different of same amino acid.


Why do chromosome mutations occur most often during nuclear divisions?

Chromosome mutations occur during nuclear division because when the sequence of nucleotides are being placed substitutions, and frameshifts can occur, causing mutations. Substitution is when one nucleotide replaces another and frameshift mutation is when a nucleotide deletes, causing codons to be incorrectly read.

Why does variation occurs?

Variation occurs because of mutations in the genetic code.Mutaions occur when one of the nitrogen bases are in the wrong spot like if aa is next to each other in the wrong sequence then the mutations occur

Mutations in DNA often occur during replication During which phase of the cell cycle do such mutations occur?

Interphase


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.

Why does a single gene mutate?

A single gene will mutate when DNA replication did not occur properly. It means that when replicating, the DNA only slipped up on a single gene when copying, causing a mutation. Mutations are accidental and are not done on purpose.


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


Can more than one mutation occur in a single organism?

Yes, mutations can occur all over at the same time. For example in a multicellular organism a gamma ray or x-ray photon passing through the organism can generate one or more mutations in every cell that the photon passes through. Another example mutagenic chemicals can produce many mutations in every chromosome.
