Dna molecule that can replicate independently
WebThe term “second chromosome” means that the other large molecule of DNA, a replicon, carries genes essential for growth and function, even though the replication is more plasmid-like. The line between chromosomes and plasmids is often blurred due to the presence of essential genes on the plasmids. WebThe Structure and Function of DNA. Biologists in the 1940s had difficulty in accepting DNA as the genetic material because of the apparent simplicity of its chemistry. DNA was known to be a long polymer composed of only …
