Question 31

A state-of-the-art DNA origami nanostructure designed for targeted drug delivery consists of a self-assembled bundle of $8$ identical engineered DNA scaffold strands.

The entire assembled nanostructure has an approximate relative formula mass ( $M_r$ ) of $18, 400, 000, 000$ .

What is the approximate relative formula mass of the DNA nanostructure written in standard form?

[2]

What is the approximate relative formula mass ( $M_r$ ) of each of the $8$ individual DNA scaffold strands?
