Nucleotides

Question 1

What are nucleic acids?

Answer 1

-large molecules contained in the nucleus

Question 2

What are the 2 nucleic acids?

Answer 2

-DNA + RNA
-polymers made of many monomers

Question 3

What are the 3 structures in a nucleotide?

Answer 3

-phosphate group
-nitrogen containing organic base
-pentose sugar

Question 4

RNA sugar

Answer 4

-ribose
-polymers of nucleotides

Question 5

DNA sugar

Answer 5

-deoxyribose

Question 6

What are the organic bases?

Answer 6

-adenine
-cytosine
-guanine
-uracil

Question 7

How do nucleotides join together?

Answer 7

-phosphodiester bonds
-formed in condensation reactions

Question 8

DNA nucleotide structure

Answer 8

-double helix
-has 2 deoxyribose sugar
-2 polynucleotides joined together by H bonds
-between complementary bases
-H at 2’

Question 9

RNA nucleotide structure

Answer 9

-single polynucleotide chain
-has ribose with OH group at 2’
-presence of OH = more susceptible to hydrolysis

Question 10

What are phosphodiester bonds?

Answer 10

-separate nucleotides jointed via condensation reactions
-occur between phosphate group of 1 nucleotide and pentose sugar of the next
-chain of alternating bonds = backbone
