Nucleic acid structure refers to the structure of nucleic acids such as DNA and RNA. Chemically speaking, DNA and RNA are very similar. Chemically speaking, DNA and RNA are very similar. Nucleic acid structure is often divided into four different levels: primary, secondary, tertiary, and quaternary.
Structural bioinformatics is the branch of bioinformatics that is related to the analysis and prediction of the three-dimensional structure of biological macromolecules such as proteins, RNA, and DNA. It deals with generalizations about macromolecular 3D structures such as comparisons of overall folds and local motifs, principles of molecular ...
DNA is transcribed into mRNA molecules, which travel to the ribosome where the mRNA is used as a template for the construction of the protein strand. Since nucleic acids can bind to molecules with complementary sequences, there is a distinction between " sense " sequences which code for proteins, and the complementary "antisense" sequence ...
The primary structure of a biopolymer is the exact specification of its atomic composition and the chemical bonds connecting those atoms (including stereochemistry).For a typical unbranched, un-crosslinked biopolymer (such as a molecule of a typical intracellular protein, or of DNA or RNA), the primary structure is equivalent to specifying the sequence of its monomeric subunits, such as amino ...
Table 8 is merged to table 1; all plant chloroplast differences due to RNA edit. Table 32 is not shown on the web page, but is present in the ASN.1 format "gc.prt" release. [4] Other mechanisms also play a part in protein biosynthesis, such as post-transcriptional modification.

RNA is subdivided into many categories, including messenger RNA (), ribosomal RNA (), transfer RNA (), long non-coding RNA (), and several other small functional RNAs.. Whereas many proteins have quaternary structure, the majority of RNA molecules have only primary through tertiary structure and function as individual molecules rather than as multi-subunit structures
All living cells contain both DNA and RNA (except some cells such as mature red blood cells), while viruses contain either DNA or RNA, but usually not both. [15] The basic component of biological nucleic acids is the nucleotide, each of which contains a pentose sugar (ribose or deoxyribose), a phosphate group, and a nucleobase. [16]
