I ordered the Ancestry.com DNA test in July. I got my results back last week (it took about 3 weeks to get the results back). The results showed West African 44%, British Isles 29%, Scandinavia 12%, Finnish-Volga/Ural 11%, and uncertain 4%. was certain that Ancestry had mixed up my sample with another. Then 4 months after receiving my âincorrectâ DNA results from Ancestry.com, my 86 year old mother revealed that my biological father was in fact a long time family friend and not the father who raised me. My own mother confirmed the DNA test results.
In genetics, complementary DNA (cDNA) is double-stranded DNA synthesized from a messenger RNA (mRNA) template in a reaction catalysed by the enzyme reverse transcriptase. cDNA is often used to clone eukaryotic genes in prokaryotes.
-Gene therapy is one practical application of vectors. -A vector is used in rDNA technology b/c any DNA that is inserted in the vector will be replicated in the process. Serve as a vehicle for the replication of a desired DNA sequence-A virus containing a new gene can insert the gene into a cell.A vector is used in rDNA technology b/c any DNA that is inserted in the vector will be replicated in the process.
