Since the plastic has more electrons than protons, it has a negative charge. Since their fingers gave up some electrons, their skin now has more protons than electrons so it has a positive charge. The positive skin and the negative plastic attract each other because positive and negative attract. Explore
DNA is single stranded in plasmids, which are rings of DNA in bacterial cells. Plasmid DNA is different from the chromosomal DNA in bacteria. Plasmids behave much like an immuâ¦ne system for the bacteria and are active during transference.
Small circular molecules of DNA in bacteria are called? 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. Pla â¦ smids are commonly used in Biology classes to teach students about splicing.
