Anti-parallel - is the orientations of this two solitary strands that compose a double-stranded DNA helix. Strands tend to be oriented such that one strand's 5' end is straight across from the other strand's 3' end.

Complementary - Term regularly refer to the all-natural pairing of nitrogen bases within DNA and RNA. In DNA, cytosine sets with guanine and adenine with thymine. In RNA, the thymine is replaced with uracil, which sets with adenine. Each person in these sets tend to be considered a "complements" for the various other.

Deoxyribose - A five-membered sugar band that does not have a hydroxyl group at one place, and is the sugar team for DNA.

Double-stranded helix - a standard architectural theme of DNA. Two linear strands of single-stranded DNA fold into a helical form stabilized internally by hydrogen bonds between complementary base sets.

Ester bond - In DNA, is the oxygen-carbon linkage between the triphosphate group as well as the 5' carbon of this ribose sugar group in one DNA or RNA nucleotide.

Glycosidic Bond - In DNA, is the nitrogen-carbon linkage between the 9' nitrogen of purine bases or 1' nitrogen of pyrimidine bases and the 1' carbon of the sugar team.

Helical Twist - The angular rotation had a need to get from nucleotide to a different in helical structures.

Hydrogen Bonding - Weak, noncovalent linkages between a donor and an acceptor which, when lined up close to each other, have positive electrostatic interactions. Offer tiny amount of security to DNA and RNA helices. Supply specificity of the communications between polynucleotide strands.

Hydrogen Bond Acceptor - an organization with one no-cost lone couple of electrons. In DNA and RNA, typical acceptor teams consist of: carbonyls, hydroxyls, and tertiary amines.

Hydrogen Bond Donor - an organization with a totally free hydrogen group. In DNA and RNA, typical donors consist of additional amines and hydroxyl groups.

Significant groove - In a helix, refers to the bigger of the unequal grooves that are formed due to the double-helical structure of DNA. As a consequence of the habits of hydrogen bonding between complementary bases of DNA, the sugar teams stick out at 120 degree angles from one another rather than 180. The main groove is generated because of the bigger angular distance between sugars.
