How is dna packaged inside the cell
WebThere are three main steps to DNA replication: initiation, elongation, and termination. In order to fit within a cell's nucleus, DNA is packed into tightly coiled structures called chromatin, which loosens prior to replication, allowing the cell replication machinery to access the DNA strands. WebEukaryotic Cell Division: Mitosis and Meiosis. Bacterial Chromosome Structure. Prokaryotic cells (bacteria) contain their chromosome as circular DNA. Usually the entire genome is a single circle, but often there are extra circles called plasmids. The DNA is packaged by DNA-binding proteins. The bacterial DNA is packaged in loops back and forth.
