Genetic Markers for Sex Identification in Forensic DNA Analysis
Genetic Markers for Sex Identification in Forensic DNA Analysis

... The application of amelogenin marker in forensic caseworks: The amelogenin (AMEL) locus encodes a matrix protein forming tooth enamel. Mutations in the AMEL locus can lead to the enamel defect known as amelogenesis imperfecta, which results in the abnormal formation of tooth enamel [3]. The AMEL loc ...

In addition, fluctuations in the amounts or states of other cellular components lead indirectly to variation in the expression of a particular gene and th ...

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.
