Answer 1

phosphate group
sugar
n base

Question 2

how many bonds are there in A;T pairing

Answer 2

2

Question 3

how many bonds are there in C;G pairing

Answer 3

3

Question 4

hydrogen are weak or strong bonds?

Answer 4

weak

Question 5

the process by which doublestranded DNA molecule is copied to produce two
identical DNA molecules

Answer 5

DNA replication

Question 6

Each of them would be a complex of an old (parental) and a daughter strand.

Answer 6

semiconservative replication

Question 7

DNA double helix made of two daughter strands while the parental chains would stay together.

Answer 7

conservative replication

Question 8

Replication Process would create two DNA doublechains, each of them with parts of both parents and daughter molecules

Answer 8

dispersive replication

Question 9

the Semiconservative DNA
Replication as was proven by the experimentation of …

Answer 9

Matthew Meselson and Franklin Stahl

Question 10

DNA replication occurs during the interface, particularly in the … phase because it is in this phase where the cells are growing, and performing cellular tasks and
replicating

Answer 10

synthesis phase (s phase)

Question 11

true or false: DNA has to divide first before it is copied

Answer 11

false

Question 12

3’ - 5’, synthesizes the leading strand

Answer 12

continuous replication

Question 13

Occurs in short segments called OKAZAKI fragments, synthesizes the lagging strand

Answer 13

Discontinuous replication

Question 14

Also called the unzipping enzyme

Answer 14

Helicase

Question 15

o Synthesizes short oligonucleotides (primers)
→ Also called as the initializer because it creates primer so that the DNA polymerase can figure out where to go and where to start replication

Answer 15

Primase

Question 16

Allows the leading strand to be threaded through

Answer 16

Clamp protein

Question 17

Acts as a builder because it adds new nucleotides

Answer 17

DNA polymerase

Question 18

Termed as the gluer because it glues DNA fragments together. Joins Okazaki fragments in the lagging strand

Answer 18

ligase

Question 19

synthesized continuously as a
single strand from the point of origin toward the opening
replication fork

Answer 19

Leading strand

Question 20

synthesized discontinuously
against overall direction of replication

Answer 20

Lagging strand

Question 21

series of short segments on the
lagging strand

Answer 21

okazaki fragments
