Question

question 1
match the correct item to the correct term
f. this enzyme breaks hydrogen bonds between the nucleotide base pairs to \unzip\ the double helix
c. this enzyme adds new nucleotide to an rna primer to extend the new daughter strand
m. this enzyme joins okazaki fragments to make a continuous dna strand
n. this enzyme initiates the synthesis of the daughter strand by laying down a short stretch of complimentary rna nucleotides
d. if the template strand is oriented 5 to 3 it will give rise to the
k. if the template strand is oriented 3 to 5 it will give rise to the
g. this is formed during bidirectional replication to speed up replication
i. this is where the next nucleotide is attached to the growing daughter strand
b. the meselson-stahl experiment proved this
a. dna polymerase can reverse to edit a mistake and this activity is called
a. exonuclease
b. semi-conservative replication
c. dna polymerase
d. lagging strand
e. rna polymerase
f. helicase
g. replication bubble
h. watson-crick
i. 3 end
j. single stranded binding proteins
k. leading strand
l. origin of replication
m. ligase
n. primase
o. topoisomerase

Explanation:

• Helix: Helicase breaks hydrogen bonds to unzip DNA.
• DNA polymerase: Adds nucleotides to RNA primer.
• Ligase: Joins Okazaki fragments.
• Primase: Initiates daughter - strand synthesis with RNA nucleotides.
• Lagging strand: Formed from 5' - 3' template.
• Leading strand: Formed from 3' - 5' template.
• Replication bubble: Formed in bidirectional replication.
• 3' end: Where new nucleotides attach.
• Semi - Conservative replication: Proved by Meselson - Stahl.
• Exonuclease: DNA polymerase uses this to edit mistakes.

Answer:

F. Helicase
C. DNA polymerase
M. Ligase
N. Primase
D. Lagging strand
K. Leading strand
G. Replication bubble
I. 3' end
B. Semi - Conservative replication
A. Exonuclease
