These Hfr strains were mated to F- bacteria, each with mutations in one or another known bacterial gene.

WebUnlike bacterial chromosomes, the chromosomes of eukaryotes are linear (rod-shaped), meaning that they have ends. These ends pose a problem for DNA replication. The DNA at the very end of the chromosome cannot be fully copied in each round of replication, resulting in a slow, gradual shortening of the chromosome. ... WebBacterial Chromosome.
