Strikingly, a number of TAFs resemble histones: nine of 14 TAPs contain a histone fold domain, though in most cases the TAFs lack the residues of this domain that are responsible for DNA binding.

To measure the activity of a promoter, one can link it to a reporter gene, such as the genes encoding b-galactosidase, CAT, or luciferase, and let 

the easily assayed reporter gene products indicate the activity of the promoter.

a. Usually appears in both sexes with equal frequency.

b. Tends to skip generations.

c. Affected offspring are usually born to unaffected parents.

d. When both parents are heterozygous, approximately one-fourth of the offspring will be affected.

e. Appears more frequently among the children of consanguineous marriages.

From the speed of replication, it is evident that a mammalian genome could be replicated in 1 hour if all replicons functioned simultaneously. S phase actually lasts for 6 hours in a typical somatic cell, though, which implies that no more than 15% of the replicons are likely to be active at any given moment.
