Change in Base Sequence of Dna
Transition in genetics and molecular biology refers to a point mutation that changes a purine nucleotide to another purine A G or a pyrimidine nucleotide to another pyrimidine C T. Along with substitutions mutations can also be caused by insertions deletions or duplications of DNA sequences. 133 Genetic Mutations Biology Notes For A Level Biology Notes Genetics Science Biology DNA changes are known as mutation regardless of their origin. . What differences are there in the two pieces. In the base sequence of the DNA part of the DNA changes whichcauses a change in the whole DNA which is called a mutation. A n ______ mutation refers to a mutation in which just one base is changed within the DNA sequence. Any permanent change in the DNA sequence which is caused due to the alteration in the DNA during the process of replication or induced due to environmental factors is called as mutation.
