A) They both normally exist in one copy per genome.
B) Both are specified by DNA sequences of tens of thousands of nucleotide pairs.
C) Both contain sequences that attract initiator proteins, as well as stretches of DNA rich in A-T base pairs.

The yeast origins of replication are similar to the bacterial origins in that they are A-T-rich and have particular sequences that attract replication initiator proteins. In higher eukaryotes, in contrast, the determinants of the replication origins are probably less sequence-specific. E. coli and S. cerevisiae both have relatively short origins compared to higher organisms.
