paragraph one last sentence "Children began working very long hours, enduring very hard work in poor conditions."
We need to reverse transcribe the mRNA to cDNA before PCR and NGS sequencing because the RNA can not be used by the Taq polymerase.
Enzymatic conversion of mRNA into double-stranded insert DNA can be finished via a number of special techniques. they all involve the movement of reverse transcriptase and oligonucleotide-primed synthesis of cDNA. After that, the approaches in commonplace use diverge drastically.
Messenger RNA (mRNA) vaccines educate our cells on the way to make a protein so one can trigger an immune response internal our bodies. Researchers had been reading and working with mRNA vaccines for decades.
cDNA (short for copy DNA; also known as complementary DNA) is artificial DNA that has been transcribed from a specific mRNA via a response using the enzyme opposite transcriptase. while DNA is composed of both coding and non-coding sequences, cDNA consists of the most effective coding sequences.
