In Eukaryotes, DNA replication proceeds at the rate of:
Correct answer: A. 50 base pairs per second
- A. 50 base pairs per second
- B. 40 base pairs per second
- C. 20 base pairs per second
- D. 30 base pairs per second
Explanation
Eukaryotic DNA replication typically occurs at a rate of approximately 50 base pairs per second. This rate reflects the complex nature of eukaryotic cells, which have larger genomes and more intricate regulatory mechanisms than prokaryotic cells. The process is meticulously controlled to ensure accuracy, with proofreading and repair mechanisms in place. The other options, 40, 30, and 20 base pairs per second, underestimate the replication capability of eukaryotic cells, highlighting a lack of alignment with the generally accepted data on replication speeds in these organisms.

About Structure of DNA
DNA structure includes nucleotides made of deoxyribose, phosphate and nitrogenous bases, arranged in two antiparallel polynucleotide strands. Questions cover the double helix, phosphodiester and hydrogen bonds, complementary base pairing between adenine and thymine and between guanine and cytosine, and the significance of major and minor grooves.
