Ligase " Which of the following structures indicates where DNA replication ructures indicates where DNA replication begins?
find the errors Restriction enzymes recognize specific DNA sequences and cut each strand of DNA at specific locations at the target sequence. The result of digesting a particular genome with a particular restriction enzyme is a collection of restriction fragments of defined length and composition. These can be used to generate restriction maps or create pieces with sticky ends. These sticky ends can be used to attach to other fragments that have sticky ends caused by cutting with a different...
