Question

Match the items on the left with its proper description/role on the right.

1a) in the textbox below, write the name of the item on the left and the correct letter next to it. for example if the correct choice for primase is "a", write "primase- a" in the textbox

___ leading/continuous strand ........................................a. raw material from which DNA is made

___Primer ..........................................................................b. joins Okazaki fragments together

___ ssDNAbp ..................................................................c. new DNA strand made as a single continuous piece

___ Primase ......................................................................d. replaces primer with DNA

___ DNA nucleoside triphosphate .................................e. binds to DNA to keep DNA strands separated

___ Ligase .......................................................................f. reads template to makes new DNA strand

___ DNA polymerase (1st choice).................................. g. new DNA strand made in fragments (separate pieces)

___ DNA polymerase (2nd choice) ..................................h. a short strand of RNA

___ discontinuous/lagging strand ...................................i. Makes “h” (or the item that matches “h”)

___Helicase .........................................................................j. unwinds the DNA/separates the two strands

1b. the items in the last question are involved/used in which process?

Answer 1

1)a)

Leading/continuous strand   : (c) new DNA strand made as a single continuous piece
Primer : (h) a short strand of RNA
ssDNAbp : (e) binds to DNA to keep DNA strands separated
Primase   : (i) Makes “h” (or the item that matches “h”)
DNA nucleoside triphosphate: (a) raw material from which DNA is made
Ligase : (b) joins Okazaki fragments together
DNA polymerase (1st choice) : (f) reads template to makes new DNA strand
DNA polymerase (2nd choice): (d) replaces primer with DNA
Discontinuous/lagging strand:  (g) new DNA strand made in fragments (separate pieces)
Helicase : (j) unwinds the DNA/separates the two strands

1)b) The items in the previous question are inolved in the process of DNA replication.
