A mutation is a change in the sequence of nucleotides that make up DNA. Changes can cause a change in phenotype when they change a gene or regulatory sequence, but can be silent mutations when a stretch of so called 'junk DNA' is affected.
A mutation can be either a spontaneous occurrence or induced by environmental factors such as free radicals / ionising radiation.
Mutation is considered to be the driving force behind evolution, regardless of where it all originates from: evolution (change) through mutation is a fact.
No. Mutation changes the sequence of nitrogen bases in a DNA molecule.
The change in the sequence of bases in a DNA molecule is most accurately referred to as a mutation. Mutations can occur due to errors in DNA replication, exposure to certain environmental factors, or as a result of genetic inheritance.
A mutation
A mutation is the most accurate term for a change in the sequence of bases in a DNA molecule. Mutations can be caused by various factors and can result in alterations in the genetic information carried by the DNA.
A Change in a DNA molecule is called a Mutation. This could have anything from no effect whatsoever, to causing a catastrophic disease (such as Sickle Cell Anaemia) to death.
No. Mutation changes the sequence of nitrogen bases in a DNA molecule.
A mutation in a DNA molecule is passed to offspring only when the mutation occurs in a germ cell, such as an egg or sperm cell. Mutations in other types of cells, like skin cells, do not get passed on to offspring.

A Frameshift mutation
The second DNA is an exact duplicate of the first. If not the second will not work correctly. We call this a mutation.
a kind of mutation called deletion or insertion

A genetic mutation can cause a variation, which may be harmless, or may be harmful, depending on where on the DNA molecule it occurs.
The change in the sequence of bases in a DNA molecule is most accurately referred to as a mutation. Mutations can occur due to errors in DNA replication, exposure to certain environmental factors, or as a result of genetic inheritance.
A mutation in a DNA nucleotide sequence would be more harmful than a mutation in a mRNA nucleotide sequence because it could cause the synthesis of multiple nonfunctional proteins in comparison to a mutation in a mRNA nucleotide sequence that would be less harmful because it would result in a few nonfunctional proteins.
