Hi I hope you're doing fine. I need help with these questions, please!thank you! **Replication Fork During S Phase****Diagram Explanation:**The image displays a DNA replication fork during the S phase of the cell cycle. The DNA strands are labeled 1 through 4:- Strand 1 and Strand 2 form one DNA duplex.- Strand 3 and Strand 4 form the complementary DNA duplex.**Question:**After mitosis and cytokinesis are complete, determine the distribution of DNA strands in daughter cells.**Options:**1. One daughter cell will have strands 1 and 2; another will have strands 3 and 4.2. One cell will have 1 and 3, the other will have 2 and 4.3. Each of the strands (1-4) will be in a different cell.4. All four strands will end up in the same cell, and the other cell will have the complementary strands.5. Both A and B are equally likely.

The DNA is a double stranded molecule which unwinds during replication. During replication one strand polarity of whose template is 3'-5' is synthesised in continuous manner while the other one is lagging strand synthesised in form of discontinuous okazaki fragments. Here in the question 2nd strand is continuous one while 3rd is discontinuous one.DNA replication in semi conservative in nature. Each cell will recieve half of parental and half of newly synthesises DNA. After the replication two DNA molecules will be synthesised and one of two will go into one daughter cell and other into the second daughter cell. One DNA molecule will comprise of strands 1 and 2 another molecule will have strands 3 and 4. Hence, one cell will recieve DNA molecule DNA strand 1and 2 and another will recieve DNA molecule with strand 3 and 4. Therefore, the answer will be a. One daughter cell will have strands 1 & 2, other will have strands 3 &4.
