Answer:
Step-by-step explanation:
Without additional information, it is difficult to provide a precise answer to this question. The percentage of strands of cellular DNA that will have been base edited (converted from A/T to G/C) at the targeted site after 3 or 6 days will depend on a variety of factors, such as the efficiency of the base editing technology being used, the frequency of DNA replication and repair in the cells, and the extent to which the edited DNA is retained as the cells divide.
In general, base editing efficiency can vary depending on the specific technology being used, the delivery method, and the target sequence. The percentage of edited DNA can also depend on the rate of cell division and the ability of the edited DNA to be replicated and retained during cell division. Therefore, the percentage of edited DNA strands at the targeted site could range from a few percent to nearly 100%, depending on these factors.
It is also worth noting that the percentage of edited DNA strands in a population of cells can be measured using various methods, such as PCR and sequencing. These methods can provide information on the frequency of edited DNA strands within a population of cells, but they may not provide information on the extent to which the edited DNA is retained as the cells divide.
