Sensing the antisense: study of gene expression in differentiating
... DNA had been transcribed into RNA, by a reaction between sense and antisense transcripts of the specific gene locus. The sense transcript is the RNA strand transcribed from the DNA sequence of a gene that is later translated into a protein (mRNA). The antisense transcript is the RNA strand that orig ...

Point mutation
A point mutation, or single base modification, is a type of mutation that causes a single nucleotide base change, insertion, or deletion of the genetic material, DNA or RNA. The term frameshift mutation indicates the addition or deletion of a base pair. A point mutant is an individual that is affected by a point mutation.Repeat induced point mutations are recurring point mutations, discussed below.
