Question

Free nucleotides are added to a growing daughter strand by...

hydrogen bonds between the sugar and phosphate groups of the nucleotides.
a reaction between the 5' hydroxyl group of the growing strand and the 3' phosphate of the free nucleotides.
a reaction between the 3' hydroxyl of the growing strand and the 5 'phosphate of the free nucleotides.
hydrogen bonds between the nitrogenous bases of free nucleotides.
a reaction between the 5' phosphate group of the growing strand the 3' hydroxyl group of the free nucleotides.

Answer 1

a reaction between the 3' hydroxyl of the growing strand and the 5 'phosphate of the free nucleotides.

Step-by-step explanation:

Strands grow 5' to 3'. Phosphate is on the 5' carbon while the -OH group is on the 3' carbon.
