Dino-DNA Analysis

In order to compare nucleotide and DNA sequences of different organisms, a database hosting a number of nucleotide sequences is used, BLAST is one such example. BLAST database is a useful tool in determining nucleotide and protein sequencing. This is because a nucleotide query is fed into the database and various sequences that closely match these results are consequently displayed in a different window. A mathematical function knows as the E value is used to compare how closely related the sequences are. Based on the results, a lower value connotes a significant relation to the DNA sequence. A few of the organisms that had sequences which best matched the dinosaur DNA Sequence include; bacillus subtilis BEST7003 DNA, shuttle vector Ptbr101-CM DNA, cloning vector Pwh1274, dengue virus type 4 vector p4, suicide plasmid pEE3, bacillus intermedius plasmid pET3xa- barn36, ubiquitin protease vector, adenoviral vector Ad- SAR1-x/AS, chimeric dengue virus vector p4 (delta 30) – D3L-ME, RNA transcription vector pBRD12 and artificial DNA cloning vector pIN-III-omp3 among others where all the sequences mentioned above have the same E values of 2e- 128.

Using the random query nucleotide sequences, a number of results with varying E values emerge. This shows that the BLAST database has sequences which can be entered in the query box in order to determine nucleotide and protein sequencing. Apparently, this does not agree with Dr. Wu’s argument on the use of restriction enzymes in splicing fragmented pieces of DNA. On the other hand, Michael Crichton typed random DNA sequences to find BLAST results. The word Dinosaurian is related to the dinosaurs. Dr. Mark chose Gallus gallus as his living dinosaur whose common name is the red fowl. He chose the name because he was passionate with the fowls. The next best match is Pseudopodoces humilis commonly known as the groundpecker. The name was chosen because of its association to the Himalayas. Mark found out that the amino acid sequence gave a protein chain which showed that the organism he subjected to analysis was the erythroid transcription factor of Gallus gallus.
