all mutations in terms of DNA happen in a gene. here it has to be noted that a gene is made up of two strands of nucleotides which are made up of amino acids. when mutations occur the sequence of nucleotides may change. sometimes a nucleotide may become missing hence the sequence of the strands change. mutations can be harmful but also very beneficial.

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.
How do new traits arise to create genetic variability?
Random mutations of DNA happen and these get inserted into the gene pool as the species breed.
Does gene mutations only temporarily change DNA structure when it repairs itself?
Mutations are permanent.
A sudden permanent change in a organisms dna called?
Gene
What would happen to a protein if the gene was changed DNA?
Change the DNA code & you change the protein.
Changes in DNA sequence of a single gene are called?
Changes in a DNA sequence of a single gene is called a point mutation. These mutations can be harmful or not to the organism.
Gene mutations can best be described as changes in the?
nucleotide base sequence in DNA.
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.
Can some DNA mutations be beneficial to an organism?
Gene mutations may have positive or negative effects. Without "positive" gene mutations, a species would not be able to improve itself over time, in order to make it more it more adaptable to its environment. "Negative" gene mutations, by their very nature and definition, tend not to be able to survive in their environment.
What is the difference between gene and chromosomal mutation?
A gene mutation is a permanent change in the DNA sequence that makes up a gene. Mutations range in size from a single DNA building block (DNA base) to a large segment of a chromosome. A chromosomal mutation is a mutation involving a long segment of DNA, it is a any change in the structure or arrangement of the chromosomes. These mutations can involve deletions, insertions, or inversions of sections of DNA. In some cases, deleted sections may attach to other chromosomes, disrupting both the chromosomes that loses the DNA and the one that gains it.It is also referred to as a chromosomal rearrangement The differences between Gene mutation and Chromosome mutation are ; 1- Chromosome mutations involve changes in the structure of a chromosome OR the loss or gain of a chromosome while Gene mutations involve a change in the nucleotide -base sequence of a gene on a DNA molecule. 2- Chromosomal mutations are changes in the structure or the numbers of chromosomes (a gain or loss). Gene mutations involve changes in the nucleotide sequence of the DNA molecule. 3-A gene mutation is a permanent change in the DNA sequence that makes up a gene. Mutations range in size from a single DNA building block (DNA base) to a large segment of a chromosome while a chromosomal mutation is a mutation involving a long segment of DNA, it is a any change in the structure or arrangement of the chromosomes. These mutations can involve deletions, insertions, or inversions of sections of DNA. In some cases, deleted sections may attach to other chromosomes, disrupting both the chromosomes that loses the DNA and the one that gains it.It is also referred to as a chromosomal rearrangement 4-gene mutation is just a substitute in any old random nucleotide for any old random nucleotide chromosome mutation is missing of chromosome or +1 chromosome (down's syndrome).
What could happen to DNA that would cause a change in trait or a new trait to be expressed?
That would be a mutation. There are several types of mutations such as silent, nonsense, missense mutations along with inserstions, deletions and amplifications
