whereas the other's runs in the 3' to 5' direction (Figure 4). It's also critical to understand that the specific sequence of A, T, C, and G nucleotides within an organism's DNA is unique to that ...

This phenomenon is known as complementary base pairing (Figure 4), and it results in the production of two complementary strands of DNA. Base pairing ensures that the sequence of nucleotides in ...

Nucleotides are abundant in the cell's nucleus. Nucleotides are the units which, when linked sugar to phosphate, make up one side of a DNA ladder. During DNA replication, special enzymes move up ...

Chances are you've seen an illustration of DNA's double-helix structure and even pictures of the chromosomes that comprise the human genome. But where and how does the famous double helix fit into ...

But three years ago, chemistry professor Floyd Romesberg of the Scripps Research Institute in California and colleagues extended this alphabet, reporting the creation of additional artificial ...

The genetic code is the set of rules that defines how the information encoded in DNA is translated into proteins. The code consists of 64 codons, each composed of three nucleotides (a triplet). Each ...

The basic units (monomers) of DNA are nucleotides. These nucleotides consist of a deoxyribose sugar, phosphate and base. The nucleotides are identical except for the base, which can be an adenine ...

Each strand can be used as a template to create a new DNA molecule. Free DNA nucleotides – needed to form the new strands. DNA polymerase – an enzyme that adds new nucleotides to a growing str ...
