You are studying a new virus with a DNA genome of 12 Kb. It can synthesize DNA at a rate of 400 nucleotides per second. If the virus uses theta replication, how long will it take to replicate its genome

15 seconds

Explanation:

Theta replication of Human DNA is bidirectional

The DNA genome = 12kb = 12000 b

for Theta replication of Human DNA  800 nucleotide are added every second

therefore for a DNA with 12000 genome it will take

= 12000/800 = 15 seconds to replicate its genome of 12kb(12000 b)

note : A Theta structure is an intermediate structure formed during the replication of a circular DNA molecule

micro/nanoscale topography surface exhibits many prominent properties and is extensively employed in biomedical device, microfluidic device and energy device fabrication. additionally, the clinical applications of biomaterials can be largely expanded with of nanostructured surfaces.
