Biotin supplements have been studied as a treatment for a number of conditions. In people with type 2 diabetes, early research suggests that a combination of biotin and chromium might improve blood sugar. On its own, biotin might decrease insulin resistance and nerve symptoms related to type 2 diabetes.
To be able to replicate, the cell has to unfold and unwind the DNA, and also has to separate the two strands from each other. The cell has a complex machinery to perform these tasks. When it is time to replicate, special initiator proteins attach to the DNA at regions called replication origins.These regions are characterised by a weak bond between the two DNA strands.he cell has a complex machinery to perform these tasks.

Helicases are enzymes that bind and may even remodel nucleic acid or nucleic acid protein complexes. There are DNA and RNA helicases. DNA helicases are essential during DNA replication because they separate double-stranded DNA into single strands allowing each strand to be copied.During DNA replication, DNA helicases unwind DNA at positions called origins where synthesis will be initiated.DNA helicase continues to unwind the DNA forming a structure called the replication fork, which is named for the forked appearance of the two strands of DNA as they are unzipped apart.he process of breaking the hydrogen bonds between the nucleotide base pairs in double-stranded DNA requires energy. To break the bonds, helicases use the energy stored in a molecule called ATP, which serves as the energy currency of cells.
