In this article we will discuss about the top two techniques used for introduction of foreign DNA without vectors. The techniques are: 1. Electroporation Technique 2. Microinjection Technique Some direct methods have also been developed for transferring DNA of one organism to a recipient without the participation of a vector. Two such methods are: 1. Electroporation technique and 2. Microinjection [...]
The following points highlight the top six repair mechanisms of damaged DNA. The repair mechanisms are: 1. Photo Reactivation 2. Excision Repair 3. Re-Combinational Repair Mechanism 4. Repair of DNA by Homologous Recombination 5. SOS Repair of Damaged DNA 6. Mismatch Repair. Repair Mechanism # 1. Photo Reactivation: We know that exposure of UV-irradiated bacteria immediately afterwards to visible light [...]
The below mentioned article provides notes on DNA replication in prokaryotic and eukaryotic organisms. Notes # Meaning of DNA Replication: A double-stranded DNA molecule is capable of producing two identical molecules from nucleotide monomers with the help of some proteins. This is known as DNA replication. DNA needs replication, because every cell produced by division of a pre-existing cell must [...]
