No, Snickers is a chocolate bar made by Mars, Incorporated. It consists of peanut butter nougat topped with roasted peanuts and caramel, covered with milk chocolate.
A cDNA sequence is derived from the transcript by reverse transcription and will, therefore, also contain the 5' and 3' UTRs. For example, see this schematic diagram of an unspliced transcript: The CDS of the gene depicted in image above will only contain the ATG, the STOP and the two green regions (exons).The cDNA will contain all that and, in addition, the two UTRs. Of course, both the cDNA and the CDS will not contain the introns.he CDS of the gene depicted in image above will only contain the ATG, the STOP and the two green regions (exons). The cDNA will contain all that and, in addition, the two UTRs.
cDNA construction [edit]. Once mRNA is purified, oligo-dT (a short sequence of deoxy-thymine nucleotides) is tagged as a complementary primer which binds to the poly-A tail providing a free 3'-OH end that can be extended by reverse transcriptase to create the complementary DNA strand.DNA Library vs. Genomic DNA Library [edit]. cDNA library lacks the non-coding and regulatory elements found in genomic DNA. Genomic DNA libraries provide more detailed information about the organism, but are more resource-intensive to generate and maintain.
