In order to have a better understanding of one model you can use for data-driven decision making, your assignment is to explore the attributes and […]

The interaction between bases on different strands of DNA molecules depends somewhat on the identities of neighboring bases. For example, the melting temperature of an oligonucleotide with the sequence 5′-GGGGGAAAAA-3′ is different than that of 5′-GAGAGAGAGA-3′ even though both contain the exact same number of G-C and A-T base pairs. […]
