What Region of the Chromosome in E

Question

What region of the chromosome in E. coli is involved in the replication termination process?
A) oriC
B) ter
C) TATA box
D) att
E) dif

Accepted Answer

The ter region of the E. coli chromosome is involved in the replication termination process. It contains multiple ter sites that bind to the Tus protein, which acts as a roadblock to the replicative helicase, leading to the termination of DNA replication. The oriC region is the origin of replication, att refers to attachment sites used by bacteriophages, and dif is involved in chromosome dimer resolution. The TATA box is a eukaryotic promoter element and not found in bacterial chromosomes.
