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 ...

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 ...

As the RNA polymerase continues down the strand of DNA, more nucleotides are added to the ... area of the growing RNA strand (Figure 4). Interestingly, this base substitution is not the only ...

A team discovers a new family of enzymes capable of inducing targeted cuts in single-stranded DNA A few years ago, the advent of technology known as CRISPR was a major breakthrough in the scientific ...

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 ...

People genetically susceptible to Huntington's disease often see their movement, mood, and cognition decline slowly over time. The cause is related to expansion of repeating DNA units, in which ...

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 ...

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 ...
