An experiment is performed where the RNA primers are labeled with a fluorescent marker that glows when viewed with a microscope. How could this technique distinguish the leading strand from the lagging strand of a replication fork? Explain your answer by giving a brief description of the differences between the two strands.

RNA primers on the leading and lagging strands
The diagram below shows a replication bubble with synthesis of the leading and lagging strands on both sides of the bubble. The parental DNA is shown in dark blue,the newly synthesized DNA is light blue, and the RNA primers associated with each strand are red. The origin of replication is indicated by the black dots on theparental strands.Rank the primers in the order they were produced. If two primers were produced at the same time, overlap them

Bound to an enhancer to regulate transcription. D. Asscoiated with DNA to make chromatin. What is the role of DNA ligase during DNA replication? A. It unwinds the parental double helix. B.

a) Suppose you label dividing cells with ^32P. In which DNA molecules will the radioactivity be incorporated if you were to look during metaphase? b) Suppose you are examining the above cells after replication. In which DNA molecules will the radioactivity be present? In one picture, draw a schematic indicating how DNA is synthesized bi-directionally. The schematic should indicate which are the lagging strands, which are the leading strands, where the RNA primers are, and the 3' and 5' orientation...
