A Situation Where Mtdna Might Be Used Is What

Mtdna testing can provide some kinds of information about ancestry not always apparent from regular dna testing.

Therefore a person s mtdna is probably identical to that of his or her direct maternal ancestor a dozen generations ago and this fact can be used to connect people across decades. Its use has also been recommended in taxonomic studies with the proposal that all described species are given an mtdna sequence tag or bar code hebert et al. For us non scientists because mtdna is shared among all people with the same maternal ancestry it can provide some of the clearest proof of relationships among people with the same mother grandmother great grandmother and so on. Interestingly mitochondrial dna mtdna is more similar to bacterial dna.

The mtdna holds the instructions for a number of proteins and other cellular support equipment across 37 genes. What are some of the situations where mtdna may be used and some of the benefits of doing so. The following questions have three parts and an answer to each of them is required. The repeated segments on the dna strand are called vntrs.

What are some effective means to prevent contamination. Dna samples should not be stored where. Rflp was on the first tests used for dna analysis. Mitochondrial dna has therefore remained the marker of choice in many population biogeographic and phylogenetic studies.
