Mutation of the genetic code causes DNA variation in organisms. For example, during DNA replication, one nitrogen base may be substituted for another, or an extra base can be added, or a nitrogen base can be skipped. If any of these mutations occur during the formation of gametes (sex cells), then the offspring that receives the mutation may have a genetic disorder.

Discuss the causes of variation Living organisms?
Causes of variation is random mutation. Random mutations constantly occur in the genomes of organisms; these mutations create genetic variation. If all living things were same, we will all use up one type of food as our nutrient source and eventually we will run out of food to consume.. making less likely for us to survive..
The abiotic and biotic conditions of mountain ranges vary with?
Sunlight hits the mountain only one side of it that causes variation
Which characteristic of DNA determines the variation of genetic expression in phenotypes?
The gene sequence of a DNA determines the variation of genetic expression in phenotypes.
What is the ultimate source of genetic variation and the bases for the diversity of life on earth?
mutation
What are variation?
gray wolves variation trait
Molecules responsible for hereditary and variation of organisms?
DNA is responsible in most organisms, but RNA is responsible for heredity and variation of a lot of viruses.
What kind of reproduction causes variation in organisms?
Sexual reproduction causes most variation in organisms. This is because genes get mixed up in the process whereas in asexual reproduction the offspring is genetically identical to the parent.
How do variation occur in asexually reproducing organisms?
mutation of the DNA is the only way asexually reproducing organisms can obtain variations in their population
What causes diversity of organisms?
the genetic variation isappearanceor the genes members of the same species of the same group.
Where does variation occur?
Variation or mutation occurs within the DNA. It is a natural result of the replication process, or the copying of one DNA strand to make new DNA during reproduction. If the new mutation ends up making some kind of variation that does not kill the organism, then the variation will be passed on to new generations. This is how new traits are formed. When the variation is actually more useful than a trait that the organism's parents had, that new variation will be passed along as a survival trait.

Natural selection causes changes in populations of organisms not individual organisms because?
differential reproductive success caused by genetic variation is necessary for the process of natural selection.
In DNA what varies from one nucleotide to another.?
The nitrogenous base is what causes variation. The deoxyribose and phosphate group are the same on all nucleotides.
What varies in one nucleotide to another in DNA?
The nitrogenous base is what causes variation. The deoxyribose and phosphate group are the same on all nucleotides.
Which is a source of genetic variation in sexually-reproducting organisms?
Basic source of variation in all organisms is mutation .
Which components varies from one Nucleotide to another in DNA?
The nitrogenous base is what causes variation from one nucleotide to another in DNA. The deoxyribose and phosphate group are the same on all nucleotides.
