i3 dna cloning - ชีวเคมี กำแพงแสน Biochemistry KU KPS

... There are a variety of different procedures for cloning DNA into either plasmid or viral vectors but the basic scheme of events is broadly the same. To clone into a plasmid vector, the circular plasmid DNA is cut with a restriction enzyme (see Topic I1) that has only a single recognition site in the ...

DNA supercoil



DNA supercoiling refers to the over- or under-winding of a DNA strand, and is an expression of the strain on that strand. Supercoiling is important in a number of biological processes, such as compacting DNA. Additionally, certain enzymes such as topoisomerases are able to change DNA topology to facilitate functions such as DNA replication or transcription. Mathematical expressions are used to describe supercoiling by comparing different coiled states to relaxed B-form DNA.As a general rule, the DNA of most organisms is negatively supercoiled.
