About 3%-5% of people become carriers of the bacteria after the acute illness. Others suffer a very mild illness that goes unrecognized. These people may become long-term carriers of the bacteria -- even though they have no symptoms -- and be the source of new outbreaks of typhoid fever for many years.thers suffer a very mild illness that goes unrecognized.

This is the parent strand of DNA which runs in the 3' to 5' direction toward the fork, and it's able to be replicated continuously by DNA polymerase. The other strand is called the lagging strand. This is the parent strand which runs in the 5' to 3' direction toward the fork, and it's replicated discontinuously. Now let's talk about the difference between continuous and discontinuous replication.
1 Elongation - the covalent addition of nucleotides to the 3' end of the growing polynucleotide chain; this involves the development of a short stretch of DNA that is transiently single-stranded.  Termination - the recognition of the transcription termination sequence and the release of RNA polymerase.
