Animal cells don't have cell walls so there is free entry of water & excess is removed
Plant cell walls are completely permeable, but only until the cell is turgid
After that it would restrict water I.e to prevent it from bursting

Base pairing occurs during translation ( between codons & anticodons)
Purines have a double ring structure where as pyrimidines have a single ring
Base pairs are of equal lengths
Uracil forms 2 hydrogen bonds with adenine
So statements 1& 3 are correct
