Question
Identify the role of the following components of DNA replication bymatching them with their descriptions. (There are extra roles justto trick us)COMPONENTS` 1.Gyrase 2. Helicase
3. SSBs
4. DNA polymerase III
5. Leading strand
6. DNA polymerase I
7. DNA ligase
8. Okazaki fragments
DESCRPTION OF ROLE
a. Catalyzes phosphodiester bonds between adjacentfragments.
b. Adds DNA to the leading andlagging strands while checking for and repairing errors.
c. Joins independent fragments ofDNA on the lagging strand by phosphodiester bonds.
d. Breaks hydrogen bonds inbetween base pairs.
e. is established by beginningreplicationat a 3' end, where and RNA primer has beenattached.
f. Prevents unwound parenttemplate strands from winding back together.
g. are short DNA sequences that form the laggingstrand.
h. unwinds the double helix
i. lays down RNA primers needs byDNA polymerase III to add DNA nucleotides to a complementaystrand.
j. replaces RNA primers on thelagging strand with DNA bases.
COMPONENTS` 1.Gyrase 2. Helicase
3. SSBs
4. DNA polymerase III
5. Leading strand
6. DNA polymerase I
7. DNA ligase
8. Okazaki fragments
Explanation / Answer
1.Gyrase h. unwinds the double helix so that it canduplicate2. Helicase . Breaks hydrogen bonds in between base pairs 7. DNAligase b. Adds DNA to the leading and lagging strands while checking forand repairing erros .
8. Okazaki fragments g. are short DNA sequences that form thelagging strand
6. DNA polymerase I i. lays down RNA primers needs by DNApolymerase III to add DNA nucleotides to a complementay strand
4. DNA polymerase III c. Joins independent fragments of DNA on thelagging strand by phosphodiester bonds
5. Leading strand e. is established by beginning replicationat a 3'end, where and RNA primer has been attached.
3. SSBs f. Prevents unwound parent template strands from windingback together.
