The double-stranded structure of DNA provides a simple mechanism for DNA replication. Here, the two strands are separated and then each strand's complementary DNA sequence is recreated by an enzyme called DNA polymerase. This enzyme makes the complementary strand by finding the correct base through complementary base pairing and bonding it onto ...
For example, imagine a simple form of cancer that is trigged by a small number of genes. Here we are examining a suspect gene and three other genes that are suspected to be involved in the processes. This chart shows a hypothetical data set of 10 people and their cancer status as well as if they possess the four genes of interest.
DNA sequencing is the process of determining the nucleotide sequence of a given DNA fragment. The sequence of the DNA of a living thing encodes the necessary information for that living thing to survive and reproduce. Therefore, determining the sequence is useful in fundamental research into why and how organisms live, as well as in applied ...

As of May 2019 (v 3.1.5), Phylo comes in three game modes: . Story mode, with levels arranged in a guided tutorial; The original Phylo mode, with the choice of diseases; A new Ribo mode for RNA molecules, where both sequences and RNA secondary structures (stem-loops) are aligned.
The system of DNA profiling used today is based on PCR and uses simple sequences [6] or short tandem repeats (STR). This method uses highly polymorphic regions that have short repeated sequences of DNA (the most common is 4 bases repeated, but there are other lengths in use, including 3 and 5 bases).

Scientists say using math to sort through DNA could help investigators put stubborn cold cases to rest. The approach combines the relatively new field of forensic genetic genealogy—solving crime ...
