DNA Replication

Question 1

Adenine goes with

Answer 1

Thymine (or uracil in RNA)

Question 2

Guanine goes with

Answer 2

Cytosine

Question 3

Purines

Answer 3

Adenine and guanine

Question 4

Pyrimidines

Answer 4

Cytosine and thymine (or uracil in RNA)

Question 5

Two hydrogen bonds

Answer 5

Adenine and thymine (or uracil in RNA)

Question 6

3 hydrogen bonds

Answer 6

Cytosine and guanine

Question 7

End that DNA can be built off of

Answer 7

3’

Question 8

Deoxyribose

Answer 8

Sugar that is in a nucleotide (it’s ribose in RNA)

Question 9

Phosphodiester bond

Answer 9

Bond between the 3’ on the deoxyribose sugar and the phosphate group on the new nucleus acid

Question 10

Semi-conservative replication

Answer 10

Part of the original strand is conserved in each new DNA strand

Question 11

Replication fork

Answer 11

Where H bonds break (starting point)

Question 12

Replication bubbles

Answer 12

Are formed to replicate DNA quickly

Question 13

Nucleotide triphosphate

Answer 13

Two phosphates are removed to provide energy and a nucleotide

Question 14

Helipads

Answer 14

Untwists parental strand

Question 15

Topoisomerase

Answer 15

Relieves tension in front of replication fork

Question 16

Promise

Answer 16

Enzyme that makes primers

Question 17

Single-strand binding proteins

Answer 17

Line up along unpaired strands to hold them apart

Question 18

DNA polymerase 3

Answer 18

Adds nucleotides

Question 19

RNA Primer

Answer 19

Piece of RNA that tells DNA where to start copying

Question 20

Polymerase roles

Answer 20

Helps connect Okazaki fragments, adds new DNA to primer location, helps correct mistakes in copying DNA

Question 21

Leading strand

Answer 21

The parent strand has 3’ end and new strand has 5’ end and builds in on 3’ end. Only needs one primer
