Deoxyribonucleic acid or DNA is the molecule of heredity. It contains thc genetic blueprint far life. For organisms to grow and repair damaged cells, cach cell must bc capable of accurately copying itsclf. So how does the structure of DNA allow it to copy itself so accurately? Model 1 - The Structure of DNA Helix Model of DNA N de Phosphate
DNA replication is semi-conservative because when a new double-stranded DNA molecule is formed: • One strand is from the original template molecule (i.e. conserved) • One strand is newly synthesised (i.e. not conserved)
DNA replication is the process in which DNA is copied. It occurs during the synthesis (S) phase of the eukaryotic cell cycle. DNA replication begins when an enzyme, DNA helicase, breaks the bonds between complementary bases in DNA (see Figure below).
