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.
Definition of Nondisjunction. Nondisjunction: Failure of paired chromosomes to separate (to disjoin) during cell division, so that both chromosomes go to one daughter cell and none go to the other.Nondisjunction causes errors in chromosome number, such as trisomy 21 (Down syndrome) and monosomy X (Turner syndrome).efinition of Nondisjunction.
