WebDNA gyrase is an essential bacterial enzyme that catalyzes negative supercoiling of plasmid and chromosomal DNA. In the supercoiled state, DNA adopts a branched and interwound conformation that allows the large chromosome to function in the highly constrained space of a bacterial cell. WebDNA sequence elements within oriC that are important for its function include DnaA boxes, a 9-mer repeat with a highly conserved consensus sequence 5' – TTATCCACA – 3', that …

WebA. Negative supercoiling increases the size of the chromosome, making it easier to replicate. B. Negative supercoiling decreases chromosome compaction, which increases DNA synthesis in bacteria. C. Negative supercoiling is necessary for the binding of DnaA to the origin of replication. WebDNA is a long polymer made from repeating units called nucleotides. The structure of DNA is dynamic along its length, being capable of coiling into tight loops and other shapes. In all species it is composed of two helical chains, bound to each other by hydrogen bonds.Both chains are coiled around the same axis, and have the same pitch of 34 ångströms (3.4 nm).

WebDec 14, 2024 · Chromosomal DNA is a DNA molecule that contains all of the genetic information in an organism's genome.
