Question 1

what are phosphodiester bonds?

Answer 1

the bond between the phosphate on a nucleotide and the sugar on the adjacent nucleotides

Question 2

what does the phosphate group at the 5th pentose carbon sugar form?

Answer 2

covalent bonds with hydroxyl (OH) group at the 3rd carbon of the pentose sugar of adjacent nucleotide

Question 3

how are phosphodiester bonds broken?

Answer 3

hydrolysis

Question 4

what are hydrogen bonds?

Answer 4

• bonds formed when positive & negative regions of molecule attract each other
• when polar molecules interact they form hydrogen bonds

Question 5

are hydrogen bonds strong or weak?

Answer 5

weak interactions (single bonds) but stronger when they occur in high numbers

Question 6

where do hydrogen bonds occur?

Answer 6

in dipoles

Question 7

what do hydrogen bonds do between the moving water molecules?

Answer 7

break and reform

Question 8

what are ester bonds?

Answer 8

they form when a triglyceride from glycerol bonds with 3 fatty acids to produce 3 water molecules

Question 9

how are triglycerides broken down?

Answer 9

hydrolysis

Question 10

what are glycosidic bonds?

Answer 10

bonds formed between either carbons 1-4 or 1-6 on the glucose molecule
