Fragments
The circular DNA molecules that can be found in bacteria are called plasmids. Plasmids are a separate DNA molecule that can replicate independently of chromosomal DNA. Plasmids are commonly used in Biology classes to teach students about splicing.
Restriction enzymes
Restriction Enzymes
Transposons or transposases are molecules that can move cut pieces of DNA from one organism to another. This process can occur naturally or be artificially induced in genetic engineering techniques.
sticky ends
DNA breaks into pieces and recombines during conception. Scientists also break DNA into pieces when studying it.
on the outsides there is phosphate and a sugar called dyoxiribose...spelling... and the insides are like rungs on a ladder, theres adenine which pairs up with thymine... and guanine which pairs up with cytosine
DNA is transferred from a complex organism (human) into a simpler one (bacterium). The 2 new pieces of combined DNA are called recombinant DNA.
DNA-polymerase synthesizes DNA molecules, while DNA-ligase ca join DNA pieces together by making phosphodiester bond.
DNA ligase is the enzyme responsible for sealing the nicks in the sugar-phosphate backbone of the newly synthesized DNA strands during DNA replication. It forms phosphodiester bonds between adjacent nucleotides to join the DNA segments together.
They are called non-coding DNA. It was called "junk DNA" at one time by people doing research on DNA because they didn't think these DNA codes had any use. Now they know that they have uses and so have stopped using that name "junk DNA".
During electrophoresis, smaller pieces of DNA will migrate to the bottom of the gel first.
