• mRNA
  • DNA that has been synthesized from mRNA by the action of reverse transcriptase. (drugs.com)
  • This enzyme, which naturally occurs in retroviruses, operates on a single strand of mRNA, generating its complementary DNA based on the pairing of RNA base pairs (A, U, G and C) to their DNA complements (T, A, C and G, respectively). (wikipedia.org)
  • A poly-T oligonucleotide primer is hybridized onto the poly-A tail of the mature mRNA template, or random hexamer primers can be added which contain every possible 6 base single strand of DNA and can therefore hybridize anywhere on the RNA (Reverse transcriptase requires this double-stranded segment as a primer to start its operation. (wikipedia.org)
  • Reverse transcriptase is added, along with deoxynucleotide triphosphates (A, T, G, C). This synthesizes one complementary strand of DNA hybridized to the original mRNA strand. (wikipedia.org)
  • Because these clones consist of DNA that is complementary to mRNA, the ESTs represent portions of expressed genes. (wikipedia.org)
  • sequences
  • Once amplified, the sequence can be cut at each end with nucleases and inserted into one of many small circular DNA sequences known as expression vectors. (wikipedia.org)
  • Thus, 3n7nz A ( 1 ) has the potential for use as a fluorescent probe for structural studies of DNAs/RNAs including the detection of single-base alterations in target DNA sequences. (rsc.org)
  • thereof
  • Of the 26 TCMs investigated, all but two can be classified as non-compliant on the grounds of DNA, toxicology and heavy metals, or a combination thereof. (blogspot.com)
  • form
  • The multi-tiered approach outlined in this study provides a much-needed auditing toolkit that should swiftly form the basis of best-practice pharmacovigilance across the CAM [complementary and alternative medicines] sector. (blogspot.com)
  • found
  • The researchers also found one of the herbal medicines for sale had trace amounts of snow leopard DNA in it. (blogspot.com)
  • In addition they found DNA from pit vipers, frogs and trace amounts of cat and dog DNA. (blogspot.com)
  • seen
  • That is, a difference can be seen in the DNA sequence, but the differences have no effect on the growth or health of the person. (wikipedia.org)
