Diagram of a chromosome after dna replication
WebMar 6, 2024 · Chromosome replication begins with the binding of an initiator protein (DnaA) to an AT-rich sequence (for example TTATCCACA in E. coli) in the OriC and melts (disrupts the hydrogen bonding between) the two strands. Helicase enzymes will be added to unwind additional DNA from this point. WebA chromosome is a physically discrete portion of the genome, which carries many individual genes. Eukaryotic chromosomes are composed of chromatin, which is a …
