TīmeklisDNA 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) Meselson and Stahl treated DNA with a heavier nitrogen isotope (15N) and then replicated in the presence Tīmeklis2024. gada 19. jūl. · One of the by-products of the intense investigation of individual DNA molecules after the advent of recombinant DNA was a procedure to isolate any DNA for which one knows the sequence. This technique, called the polymerase chain reaction (PCR), is far easier than traditional molecular cloning methods, and it has …

Since the genetic code is universal, as are transcription and translation mechanisms, the transferred DNA can be translated within cells of the recipient (transgenic) organism. Fragments of DNA can be … pratthomes.com
