Answer:
creation of Okazaki fragments.
Explanation:
Replication of the lagging strand of DNA is discontinuous due to the antiparallel polarity of the two strands of DNA and the ability of DNA polymerase to replicate DNA in 5' to 3' direction only. The problem of synthesis of DNA in 5’ to 3’ direction on both template strands is solved by the synthesis of the short DNA segments at a small distance on one of the template DNA strands. These small fragments that are formed are called Okazaki Fragments and joined together by DNA ligase to form the lagging strands in DNA replication. Each of the Okazaki fragment is 100-1000 nucleotides long.
It is a natural process that occurs during DNA replication and therefore, does not include any molecular technique.

I believe the cell is a plant cell

Answer:
3:1
Explanation:
Let the allele for tall plant be T; &
The allele for short plant be t
When Mendel crossed true-breeding tall pea plants(i.e TT) with true-breeding short pea plants(I.e tt); all the offspring were tall.
TT × tt
T T
t Tt Tt
t Tt Tt
we can deduce from the punnet square that the F1 offspring are all heterozygous tall plant.
Now, if the first generation (F1) tall plants are allowed to self-pollinate; we have a cross between Tt and Tt
TT × tt
T t
T TT Tt
t Tt tt
We can see phenotypically that we have 3 tall plant(TT,Tt, Tt) and 1 short plant(tt).
Therefore the ratio of phenotypes he expected in the F2 generation is (3:1)
