Front 1

DNA replicate in order to preserve their ? and ? it on.

Back 1

code
pass

Front 2

DNA replication must be completed during a ? generation time.

Back 2

single

Front 3

DNA is generated from ?' to ?'

Back 3

5' to 3'

Front 4

The overall replication process requires the action process of 30 different ?

Back 4

enzymes

Front 5

The function of the enzymes that are involved in the replication process is to ? the strands and ? its template and produce ? new daughter molecules.

Back 5

separate
copy

Front 6

The enzyme that unzips the DNA molecule is ?

Back 6

Helicase

Front 7

The enzyme that synthesizes an RNA primer so that DNA polymerase can start adding to the strand is ?

Back 7

RNA polymerase/primase

Front 8

The enzyme that is adding bases to the new DNA chain and can proofread the chain for mistakes is ?

Back 8

DNA polymerase III

Front 9

The enzyme that removes the RNA primer, closes the gaps and repairs mismatches in the lagging strand is ?

Back 9

DNA polymerase I

Front 10

The enzyme that finally binds the lagging strand after removal of the RNA primer section is ?

Back 10

Ligase

Front 11

The enzyme that supercoils the DNA after it is synthesized is ?

Back 11

Gyrase

Front 12

In ? replication each daughter molecule is identical to the parent in composition, but only one strand is completely new.

Back 12

semi-conservative

Front 13

During semi-conservative replication, after the DNA molecule uncoils the ? bonds between the base pairs are unzipped.

Back 13

Hydrogen

Front 14

During semi-conservative replication the ? sequence of each strand is exposed to serve as templates.

Back 14

neucleotide

Front 15

In semi-conservative replication there are ?# new strands synthesized by attachment of the correct ? nucleotides to each single stranded template.

Back 15

2


complementary

Front 16

The spot where DNA helicase starts unzipping the DNA strand is known as the ? or replication.

Back 16

origin

Front 17

The origin of replication is started in an area of the DNA that is rich in Adenine and Thimine because it takes less energy to break apart the 2 ? bonds that hole them together

Back 17

hydrogen

Front 18

? synthesizes a new daughter strand of DNA using the parental strand as a template.

Back 18

DNA polymerase III

Front 19

The enzymes that hold the DNA open during replication are ?

Back 19

single stranded binding proteins

Front 20

DNA polymerase attaches at the 3' end of the RNA primer that is layed down by ?
