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.
DNA is synthesized naturally while cDNA is a form of DNA which is synthesized by the scientist for their experimental purpose. Genomic DNA contains both introns and exons but cDNA is made up of only exons, which codes for specific functions.cDNAs are much shorter, as introns can span thousands of base pairs.NA is synthesized naturally while cDNA is a form of DNA which is synthesized by the scientist for their experimental purpose.
