Everything about Mutagenesis totally explained
A process by which the genetic information of an
organism is changed in a stable manner, either in nature or experimentally by the use of
chemicals or
radiation.
Types Of Mutation
The following are the types of Mutagenesis:
PCR Mutagenesis
PCR mutagenesis is simple method for generating
Site-directed mutagenesis. This method can generate mutations (base substitutions, insertions, and deletions) from double-stranded plasmid without the need for subcloning into M13-based
bacteriophage vectors and for ssDNA rescue. The procedure involves a
PCR reaction using a supercoiled plasmid vector as the template and two synthetic oligonucleotide primers containing the desired mutation with each complementary to the opposite strands of the vector. After
PCR, the template (wild type) plasmid which is dam methylated in almost all E. coli is removed by digestion with Dpn I which is specific for methylated DNA. The mutated plasmid remains intact in the reaction.

External Link Exchanges
Do you know how hard it is to get a link from a large encyclopaedia? Well we're different and will prove it. To get a link from us just add the following HTML to your site on a relevant page:
<a href="http://mutagenesis.totallyexplained.com">Mutagenesis Totally Explained</a>
Then simply click through this link from your web page. Our crawlers will verify your link, extract the title of your web page and instantly add a link back to it. If you like you can remove the words Totally Explained and embed the link in article text.
As long as your link remains in place, we'll keep our link to you right here. Please play fair - our crawlers are watching. Your site must be closely related to this one's topic. Any kind of spamming, dubious practises or removing the link will result in your link from us being dropped and, potentially, your whole site being banned. |
