Which statement about dna replication is true?
a. eukaryotes only have one circular chromosome that unwinds at multiple locations.
b. prokaryotes only have one origin of replication to initiate replication.
c. eukaryotes can only replicate one segment of a chromosome at a time.
d. prokaryotes can only replicate their single circular chromosome in the nucleus.

The correct answer is option B, "Prokaryotes only have one origin of replication to initiate replication"

Prokaryotes have single circular molecule of DNA which has only one origin of replication per circular chromosome.  

While Eukaryotes have several origin of replication. The chromosome of Eukaryotes is linear and long due to which it has multiple replicating sites with different replication timing.  With multiple replication, the process of transcription in eukaryotes becomes fast and easy.  

Prokaryotes only have one origin of replication to initiate replication

Explanation:

hydroxyl -oh

alcohols, always polar, can form hydrogen bonds with h2o molecules

carboxyl -cooh  

cargoxylic acids, has acidic properties which is a source of hydrogen ions, found in cells in ionized for with a charge of oh-1

carbonyl > co

ketone if within skeleton, aldehyde if group is at the end of skeleton, k & a may be structural isomers, it determines 2 sugars (ketose & aldose)

amino -nh2

amines, acts as a base, it can pick up h+ ions from surrounding solution, ionized with charge of 1+

methyl ch2

addition to rna/dna affects and gene expression

phosphate -opo3 ²⁻

organic phosphates, contributes to negative charge to, molecule that it is a part of, and potential to react with h20

sulfhydryl -sh

thiols, cross-linking stabilize the protein, and it is structure
