Question 8

nucleic acids- monomers and polymers

Answer 8

nucleotides (deoxy/ribose sugar + phosphate + nitrogenous base)
DNA, RNA

Question 9

what is condensation

Answer 9

when monomers join together to form a polymer, releasing water and making a covalent bond- can be catalysed by enzymes

Question 10

what is hydrolysis

Answer 10

when water is used up, the larger polymer will split up into monomers/smaller polymers, the covalent bond is broken- can by catalysed by enzymes
