  • What is DNA Methylation?
    Life Sciences - 20 Jul 2023
    DNA methylation is an epigenetic mechanism used by cells to control gene expression. A number of mechanisms exist to control gene expression in eukaryotes, but DNA methylation is a commonly used...
  • DNA Methyltransferase Enzymes: DNMT1 to DNMT3
    Life Sciences - 20 Jul 2023
    Global cytosine methylation patterns in mammals appear to be controlled by a complex interaction of DNA methyltransferases: DNMT1, DNMT2, DNMT3A and DNMT3B.
  • Functions of Junk DNA
    Life Sciences - 20 Jul 2023
    In genetics, the term junk DNA refers to regions of DNA that are non-coding. Some of this noncoding DNA is used to produce noncoding RNA components such as transfer RNA, regulatory RNA and ribosomal...
  • Structure of DNA
    Life Sciences - 19 Jul 2023
    The discovery of DNA structure by James Watson and Francis Crick in the year 1953 is one of the most revolutionary scientific discoveries to date. However, the research leading to the discovery of...

  • Interactions That Hold DNA Together
    Life Sciences - 19 Jul 2023
    There are several interactions present within a strand (intrastrand interactions) and between two strands (interstrand) that stabilize DNA.
  • Future DNA Sequencing Techniques
    Life Sciences - 19 Jul 2023
    DNA sequencing has undergone radical advances since the first Sanger sequencing method was introduced in 1977.
  • Study sheds light on how viruses override host cell's DNA replication machinery
    News - 17 Jul 2023
    University of Pittsburgh researchers have shown for the first time how Merkel cell polyomavirus (MCV), which causes an aggressive skin cancer called Merkel cell carcinoma, initiates DNA replication in...
  • DNA origami could be used to create customized virus-like particles
    News - 17 Jul 2023
    Bioengineers have found a way to program the size and shape of virus particles by combining viral protein building blocks and templates made from DNA.
