  2. Denaturation (biochemistry) - Wikipedia

    en.wikipedia.org/wiki/Denaturation_(biochemistry)

    In biochemistry, denaturation is a process in which proteins or nucleic acids lose folded structure present in their native state due to various factors, including application of some external stress or compound, such as a strong acid or base, a concentrated inorganic salt, an organic solvent (e.g., alcohol or chloroform), agitation and radiation, or heat. [3]

  3. Protein folding - Wikipedia

    en.wikipedia.org/wiki/Protein_folding

    Denaturation of proteins is a process of transition from a folded to an unfolded state. It happens in cooking , burns , proteinopathies , and other contexts. Residual structure present, if any, in the supposedly unfolded state may form a folding initiation site and guide the subsequent folding reactions.

  4. DNA unwinding element - Wikipedia

    en.wikipedia.org/wiki/DNA_unwinding_element

    DNA unwinding at the DUE, allowing for formation of replication fork for DNA replication to occur. A DNA unwinding element (DUE or DNAUE) is the initiation site for the opening of the double helix structure of the DNA at the origin of replication for DNA synthesis. [1] It is A-T rich and denatures easily due to its low helical stability, [2 ...

  5. Protein metabolism - Wikipedia

    en.wikipedia.org/wiki/Protein_metabolism

    Protein anabolism is the process by which proteins are formed from amino acids. It relies on five processes: amino acid synthesis, transcription, translation, post translational modifications, and protein folding. Proteins are made from amino acids. In humans, some amino acids can be synthesized using already existing intermediates.

  6. Nucleic acid metabolism - Wikipedia

    en.wikipedia.org/wiki/Nucleic_acid_metabolism

    Nucleic acid metabolism is a collective term that refers to the variety of chemical reactions by which nucleic acids (DNA and/or RNA) are either synthesized or degraded. Nucleic acids are polymers (so-called "biopolymers") made up of a variety of monomers called nucleotides. Nucleotide synthesis is an anabolic mechanism generally involving the ...

  7. DNA extraction - Wikipedia

    en.wikipedia.org/wiki/DNA_extraction

    DNA extraction. The first isolation of deoxyribonucleic acid (DNA) was done in 1869 by Friedrich Miescher. [1] DNA extraction is the process of isolating DNA from the cells of an organism isolated from a sample, typically a biological sample such as blood, saliva, or tissue. It involves breaking open the cells, removing proteins and other ...

    Enzymes also help with nerve function, respiration, digestion, muscle growth and much more. "The list is very long," says Farina. "The list is very long," says Farina.

  9. DNA supercoil - Wikipedia

    en.wikipedia.org/wiki/DNA_supercoil

    DNA supercoiling is important for DNA packaging within all cells. Because the length of DNA can be thousands of times that of a cell, packaging this genetic material into the cell or nucleus (in eukaryotes) is a difficult feat. Supercoiling of DNA reduces the space and allows for DNA to be packaged.
