Answer: Lk for this plasmid = 47

Explanation:

The formula to compute Lk is given by :-

Topological Linking Number (Lk): Twist (Tw) + Writhe (Wr)

Given: A plasmid 41 twists and 6 right handed writhes.

i.e. Twist (Tw) = 41 , Writhe (Wr) = 6

Then, Topological Linking Number (Lk) for this plasmid : = 41+6

= 47

Hence, the Lk for this plasmid = 47

Red blood cells do not have a nucleus.
It does not consist of a cell membrane or a cytoplasm.
It simply only transports oxygen around the body.
