The Okazaki fragment moves the lagging strand away from the replication fork 5' --> 3'.
<h3>What does Okazaki Fragment do?</h3>
- Okazaki fragments are small stretches of DNA formed during discontinuous lagging strand synthesis during DNA replication. They are important because they allow the synthesis of both daughter strands required for cell division.
- DNA polymerases are enzymes involved in DNA replication. It synthesizes DNA only in the 5'-3' direction. However, double-stranded DNA is antiparallel, so DNA synthesis should occur in both directions. Thus, Okazaki fragments are formed during synthesis of the lagging template strand.
<h3>What is difference between leading and lagging strands?</h3>
The main difference between leading and lagging strands is that the leading strand is the DNA strand that grows continuously during DNA replication whereas the lagging strand grows discontinuously by forming short segments known as Okazaki fragments.

Answer:
250 nm
Explanation:
Data provided in the question:
Length of the bacteria cell = 2.5 micrometers (µm)
Now,
We know that,
1 m = 10⁶ µm
or
1 µm = 10⁻⁶ m
also,
1 m = 10⁹ nm
or
10⁻⁹ m = 1 nm
Therefore according to the above results we get,
2.5 micrometers (µm) = 2.5 × 10⁻⁶ m
and,
2.5 × 10⁻⁶ m = ( 2.5 × 10⁻⁶ ) × 10⁹ nm
= 2.5 × 10³
= 250 nm
Answer:
B
(The result of DNA replication is two DNA molecules consisting of one new and one old chain of nucleotides. This is why DNA replication is described as semi-conservative, half of the chain is part of the original DNA molecule, half is brand new.)
The answer is called heat energy. Hope this helps.
