how does replication occur so quickly in eukaryotes?

Question

liliakarina · Answer

There are several origins of replication and it's biderectional. There are more proteins in the DNA to release. The DNA is larger and it is linear.

thanks! one more question- why is it advantageous to have wear hydrogen bonds between complementary bases and strong covalent bonds between phosphate and deoxyribose groups in a DNA molecule?

liliakarina · Answer

Those bonds are responsible for the skeleton strands in DNA and RNA

anonymous · Answer

Eukaryotes initiate DNA replication at multiple points in the chromosome, so it goes quickly.

anonymous · Answer

I think the second question is getting at the ability of DNA to form helices or hybrids which can be broken apart for replication or transcription because of the hydrogen bonds between the strands. However the individual strands are strong because of the covalent bonds between residues. I suppose this is a good example of evolution leading to an elegant solution to a problem.
