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)
The following points highlight the top thirteen methods of gene transfer. Some of the methods are: 1. Calcium Chloride (CaCl2) Mediated DNA Transfer 2. Rubidium Chloride Mediated DNA Transfer 3. Electroporation 4. Liposome Encapsulation (Lipofection) 5. Microinjection. Gene Transfer: Method # 1.
24 Σεπ 2018 · explain how DNA is replicated accurately. explain how and why damage to DNA is repaired. Living cells must be able to duplicate their entire set of genetic instructions every time they divide. Likewise, multicellular organisms must be able to pass on complete copies of their genetic information to future generations.
The main gene transfer methods using biological means are as follows: • Bacterial gene delivery i.e. bactofection. • Delivery using a viral vector i.e. transduction
Transfection: Introduction of foreign DNA into the nucleus of eukaryotic cells. Cells that have incorporated the foreign DNA are called transfectants. Stable transfectants: Cells that have integrated foreign DNA in their genome. Transient transfectants: Foreign DNA does not integrate in the genome but
The DNA sequence of a chromosome can change in large segments as well, by the processes of recombination and transposition. Recombination is the production of new DNA molecule(s) from two parental DNA molecules or different segments of the same DNA molecule; this will be the topic of this chapter.
