Double-stranded DNA consists of two polynucleotides that are arranged such that the nitrogenous bases within one polynucleotide ... 3' to 5' direction (Figure 4). It's also critical to understand ...

all the way down to the level of the atoms that make up a single DNA base. The human body contains about 100 trillion cells, each working together in a complex symphony of interactions.

In 1950, biochemist Erwin Chargaff found that the arrangement of nitrogen bases in DNA varied widely, but the amount of certain bases always occurred in a one-to-one ratio. These discoveries were ...

After sequencing, the duet proprietary software aligns and compares sequence information from the original and copy strands, computing resolved bases that have both genetic and epigenetic information.

This discovery, along with the identification of other nitrogenous bases, laid the foundation for ... or the hydrolysis of 2-amino-4,6-dichloropyrimidine. Cytosine can also be isolated from DNA or RNA ...
