  2. Biomolecule - Wikipedia

    Examples of these include cytidine (C), uridine (U), adenosine (A), guanosine (G), and thymidine (T). Nucleosides can be phosphorylated by specific kinases in the cell, producing nucleotides. Both DNA and RNA are polymers, consisting of long, linear molecules assembled by polymerase enzymes from repeating structural units, or monomers, of ...

  3. Nucleic acid - Wikipedia

    en.wikipedia.org/wiki/Nucleic_acid

    Indeed, DNA molecules are probably the largest individual molecules known. Well-studied biological nucleic acid molecules range in size from 21 nucleotides (small interfering RNA) to large chromosomes (human chromosome 1 is a single molecule that contains 247 million base pairs [18]). In most cases, naturally occurring DNA molecules are double ...

  4. DNA - Wikipedia

    en.wikipedia.org/wiki/DNA

    For example, only about 1.5% of the human genome consists of protein-coding exons, with over 50% of human DNA consisting of non-coding repetitive sequences. [98] The reasons for the presence of so much noncoding DNA in eukaryotic genomes and the extraordinary differences in genome size , or C-value , among species, represent a long-standing ...

  5. Human genome - Wikipedia

    en.wikipedia.org/wiki/Human_genome

    Human genomes include both protein-coding DNA sequences and various types of DNA that does not encode proteins. The latter is a diverse category that includes DNA coding for non-translated RNA, such as that for ribosomal RNA, transfer RNA, ribozymes, small nuclear RNAs, and several types of regulatory RNAs.

    For example, fruit flies share 61 percent of disease-causing genes with humans, which was important when NASA studied the bugs to learn more about what space travel might do to your genes.

  7. Gene - Wikipedia

    en.wikipedia.org/wiki/Gene

    For example, The primary function of the genome is to produce RNA molecules. Selected portions of the DNA nucleotide sequence are copied into a corresponding RNA nucleotide sequence, which either encodes a protein (if it is an mRNA) or forms a 'structural' RNA, such as a transfer RNA (tRNA) or ribosomal RNA (rRNA) molecule.

  8. RNA - Wikipedia

    en.wikipedia.org/wiki/RNA

    Catalytic RNA molecules were discovered in the early 1980s, leading to a 1989 Nobel award to Thomas Cech and Sidney Altman. In 1990, it was found in Petunia that introduced genes can silence similar genes of the plant's own, now known to be a result of RNA interference. [80] [81]

  9. Biomolecular structure - Wikipedia

    en.wikipedia.org/wiki/Biomolecular_structure

    Biomolecular structure is the intricate folded, three-dimensional shape that is formed by a molecule of protein, DNA, or RNA, and that is important to its function.The structure of these molecules may be considered at any of several length scales ranging from the level of individual atoms to the relationships among entire protein subunits.
